d. Features of Raider Outboard

Raider's new TLDI 50 represents a quantum leap forward in outboard engine technology. The beauty of the TLDI 50 is its simplicity. It's based on the supply chain of the

Tohatsu/Nissan M50D2 and apart from fuel and air delivery modifications, with the addition of a sophisticated engine management system that supports submersibility and multi-fuel operation; it's still a two-stroke engine no other engine can match in terms of reliability.

There is an air compressor, an air/fuel rail, and six injectors. Three fuel injectors introduce fuel into the air/fuel rail. 80 PSI fuel and air are mixed and then injected into the combustion chamber through three air injectors after the exhaust port is closed. The result is complete atomizing without having to resort to high fuel-injection pressures. A single-throttle body air intake incorporates Throttle Position Sensors for load and barometric pressure (to ascertain the correct air/fuel ratio) and along with the air; lubricating oil is carried via the crankcase to the combustion chamber. For ease of servicing the six injectors are contained in a neat extruded aluminum block, held in place to the cylinder head by just two bolts.

The 40 Raider horsepower outboard uses 90% of common 50 Raider outboards outside of engine block and heads. The Raider 40 only has two cylinders, weight under 150 pounds.

The Raider 50 & 40 offers multi-fuel operation, submersibility, no battery required, (however, this option of an enclosed battery with electric start under the cowling can be ordered), pull start, small enough to go through a submarine hatch and strong enough to operate after an air drop. It offers superior human factors design for the operator. It is lighter than any outboard motor in its class.

The Raider Outboard was designed, under contract by SOCOM, to provide an outboard that was specifically designed to the toughness of military requirements and fully submersible without bags with the ability to be cached.

What all this means for the war fighter is an outboard that is consistent, reliable, lightweight, and durable that operates on most available fuels. When submerged the Raider can be de-watered quickly - complete the mission and get home with confidence.

f. TLDI verses Carburetor

TLDI is an abbreviation that stands for Two-stroke Low-pressure Direct Injection.

The air assisted, low-pressure direct injection system has been combined with the inducted ignition system and the Engine Control Unit, which performs control or fuel mixture, injection timing and ignition timing to maximize combustion efficiency in the TLDI engine. The result is better fuel economy, lower maintenance, ability to burn multi-fuels and capable of submersion.

The air-assisted Low-pressure direct fuel injection process involves using an air compressor to pressurize the fuel supplied by the fuel pump and inject it directly into the combustion cylinder in the form of a finely atomized mixture that achieves maximum combustion efficiency.

Below is a simple diagram of how the TLDI engine operates and the conventional carburetor engine to show the differences.

Raider Installation

a. Handling Engine

! The Raider was designed to be carried by the two side rails installed to allow the outboard to be moved through submarine hatches and small areas. The handle/shifter should be upright into the hollow area to keep from getting damaged and to help in carrying the Raider. Be aware of the sharp propeller when lifting through submarine hatches.

To move engine around shop area, use a motor stand that supports engine by the transom mount.

Hand Rails – Both Sides for Carrying

WARNING

Most Rubber Inflatable Boats are rated and certified in terms of their maximum horsepower on the transom. This information is shown on the boat's certification plate. Do not equip your RIB with an outboard that exceeds this limit.

Do not operate the engine until it has been securely mounted on the boat in accordance with the instructions. Attach safety wire to boat to avoid losing the motor overboard.

b. Installation of single Engine

The Raider has been designed to be released from submarines and air dropped. This installation will discuss a typical installation – no special operations installation. Position the outboard engine at the exact center of the stern and mount it against the Rubber Inflatable Boat pad or plate. It is important to keep it centered as much as possible, Tighten clamp screws by hand DO NOT use tools to tighten clamp screws. Retighten engine clamps after 15 minutes of operation.

c. Installation of Twin Engines

When installing two outboard engines, be sure to keep an interval of 470 to 600 mm (18 to 26 inches) between the two engines. Both outboard engines should be at the exact center of the stern and mount it against the Rubber Inflatable Boat pad or plate. It is important to keep it centered as much as possible, after centering on transom tighten clamp screws of both motors by hand. The attachment of a single steering unit for dual mount assembly can be quickly placed on dual motors for control and a cable inserted from one engine to the opposite for single power to both outboards.

d. Installation of Safety Wire

To prevent loss of engine (engines) overboard, attach engine retention cable that is attached to the Raider outboard to the boat.

e. Transom Height

Close-up of mechanical components with coiled wires and a central knob (no visible text or symbols)

10-30mm (0.4-1.2 in.) Anti-ventilation Plate

The Raider has been designed to have the anti-ventilation plate at a level 10 to 30 mm (0.4 to 1.2 inches) below the bottom of the boat as shown above. Be sure the anti-ventilation plate of the Rader outboard is below the water surface when running with wide open throttle.

CAUTION

Overheating may occur if Anti-ventilation plate is at higher level than the boat as a lack of cooling water.

f. Propeller

A propeller must be selected so that the engine rpm measured at wide open throttle while cruising is within the maximum operating range. In the Raider that range is between 5150 and 5850 rpm.

To ensure optimum performance, the propeller should match the boat type and its load.

3. Raider Running

a. Fuels (Multi-fuel)

The Raider can run on jet fuels (JP-5/8), diesel fuel, kerosene, gasoline or gasohol/ethanol. There is no knob or valves to turn. If you switch from one fuel to another fuel the Raider engine will operate during transition. When using the twin engine configuration it is recommended similar fuels are used.

b. Raider Break in

10 Hours. The Raider has provided the break in at the factory. The most critical time in the life of the Raider engine is the first 10 hours of operation. Correct operation during this break-in period will prolong the life of the engine and ensure optimum performance. The procedures we follow are shown below.

Time	Break-in method	Running Conditions
0 min-	Trolling or idling speed	Cruising at minimum speed
10 min-	Throttle opening < 1/2about 3,000 rpm	-
1 hr-	Throttle opening < 3/4about 4,000 rpm	Run with full throttlefor 1min-10 min.
2 hrs-	Throttle opening 3/4about 4,000 rpm	Run with full throttlefor short time
10 hs-	Normal running	-

c. Normal Starting Procedure

Move the tilt/run lever to RUN position. Place engine in normal operating position. Connect the fuel line connector from the tank to the engine's fuel connector. Turn fuel line connector onto fuel tank connector. . = If the fuel tank has a manual vent, open it. If you don't, the engine will eventually die from fuel staryation. Squeeze fuel line primer bulb until firm.

d. After Raider Starts/Warm Up

α Check the water pump indicator. A steady stream of water indicates the water pump is working.

= IF the water pump indicator is not discharging a steady stream of water, STOP the engine when it is safe

▲ CAUTION If cooling water is not discharged and engine operation is continued, the engine will overheat and damage occur. Cooling water check port Idle port

e. Forced engine oil feeding

When the engine is new or has been left without operation for a long time execute the following operation for forcedly feeding the engine oil to the oil line before starting the Raider Engine.

1. Disconnect the link rod by turning the rod snap interlocking with the oil pump as shown in the figure.
2. Make sure the oil pump control lever is set at open side position.
3. Idle the engine for more than 30 minutes.
4. Reset the link rod to the advancer arm.

h. Shifting

= To avoid gear case damage:

DO NOT attempt to shift engine from NEUTRAL to FORWARD or REVERSE when the engine is NOT running. Clutch dogs can align lug-on-lug and result in shift linkage and lower gear case parts damage. When shifting, always wait until boat has slowed and engine is at idle speed.

Shift to FORWARD

After engine is running smoothly, turn throttle control to SHIFT position or slower. Move shift lever to FORWARD/down with a firm, quick motion. DO NOT shift engine with throttle control advanced beyond the shift position.

Close-up of a black mechanical component with a handle and two circular ports, no visible text or symbols.

• Increase Speed: Turn throttle control counterclockwise toward FAST (toward you if seated in boat next to engine).
• Decrease Speed: Turn throttle control clockwise toward SLOW (away from you if seated in boat next to engine).

Shift to NEUTRAL

Turn throttle control clockwise to the SHIFT position or slower. Move the shift lever to NEU-TRAL with a firm, quick motion.

= When shifting, always wait until boat has slowed and engine is at idle speed.

Shift to REVERSE

Turn throttle control clockwise to the SHIFT position or slower. Move shift lever to REVERSE with a firm, quick motion.

= When in REVERSE, operate with additional care as the engine has no impact protection if it hits an underwater obstruction.

!Do not operate engine in REVERSE with the tilt/run lever in TILT. Engine may tilt out of the water, resulting in loss of control.

i. Stopping Raider

1. Slow engine to idle speed.
2. Move shift lever to NEUTRAL position.
3. Press and hold stop button until the engine stops running.

k. Trailering

Place the engine in the normal vertical position. For additional road clearance, move angle adjusting rod to an outer stern bracket position. Refer to Raider Trim Angle.

= DO NOT use the tilt support as a Trailering bracket. The engine should always be resting on the angle adjusting stop rod when under full power or when trailering.

I. Tilting

= DO NOT push down on tiller handle to tilt engine.

Raise Raider

1. Move tilt/run lever to the TILT position.
2. Use tilt grip on engine cover to raise engine. When desired angle
   is reached, move lever to lock position.

Tilt the engine up entirely

! Lower Raider

1. Move tilt/run lever to RUN position. Engine will lower to set run position.

m. Trim Tab Adjustment

Trim Tab Adjustment

If straight-line cruising can not be achieved, adjust the trim tab located under the anti-ventilation plate.

■ If the boat veers toward the right, direct the trim tab towards A.
■ If the boat veers toward the left, direct the trim tab towards B.

Trim tab B A

Notes:

1. The trim tab also acts as an anode to prevent electrolytic corrosion. Therefore do not paint or grease this part.
2. After adjustment securely tighten the trim tab fixing bolt.
3. Check for looseness of the bolt and the trim tab at regular intervals. Due to corrosion, the trim tab will wear down over time.

n. Shallow Water Drive

The engines shallow water tilt is controlled by the gas assist tilt cylinder

Engage Shallow Water Drive

1. Move red button tilt/run lever to TILT position
2. Raise the engine to the desired shallow drive position.
3. When drive angle is reached, lock position.

Disengage Shallow Water Drive

1. Move red button tilt/run lever to RUN position.

Close-up of a mechanical device with a red component inserted, showing internal components and no visible text or symbols.

o. Shallow Water Operation

= DO NOT operate engine with gear case dragging on sea bottom. This can result in propeller or water pump damage.

1. Place engine in shallow water drive position. Refer to Shallow Water Drive.

a. !DO NOT operate engine in REVERSE with the tilt/run lever in the TILT position. Engine can tilt up resulting in loss of control.

1. Run at SLOW SPEEDS ONLY. Check water pump indicator often. (Note; Shallow water drive setting can be adjusted for different boat load conditions.)
2. Before operating in deep water, be sure to lower engine and move tilt/run lever to the RUN position.

! Engine does not have impact protection when operated in the shallow water drive position or when the tilt/run lever is in the TILT position. Engine will tilt up suddenly if it hits an underwater obstruction.

p. Impact Damage

Your boat and engine can be seriously damaged by a collision at high or low speeds, while trailering, or in the water.

If you hit an object, stop immediately and examine the engine for loose mounting hardware or clamp screws. Inspect for damage to stern and swivel brackets, and components in the area of impact. Also, examine the boat for damage. Tighten any loose hardware. If collision occurred in the water, proceed slowly to shore. Before operating again, inspect all components.

! Failure to inspect for damage can result in sudden, unexpected component failure and loss of boat control. Uncorrected damage can adversely affect the boat and engine's ability to resist subsequent collisions.

q. Special Operating Conditions

Sea Water

Fresh water flushing is recommended after use in salt, polluted, or brackish water to prevent deposits from clogging the cooling passages.

Check gear case anodes for deterioration, and replace if necessary.

During long periods of non-use, tilt engine so that the gear case is out of the water, unless the temperature is below 32^ F ( 0^ C). When removing engine from water, allow cooling system to drain completely by placing engine in upright position.

Weedy Water

Weeds can block the water intakes and cause engine to overheat. Weeds on the propeller will cause engine to vibrate.

Run at slow speeds and reverse engine frequently to clear weeds from propeller. Check water pump indicator often. Remove weeds from propeller and water intakes before operating in clear water.

Freezing Weather

To avoid engine damage, keep the gear case submerged in the water at all times. Before operating in freezing temperatures, check gear case lubricant. If leakage is found, gear case seals will need service.

When removing engine from water, keep the engine in an upright position until the cooling system is completely drained.

= Water that leaks into gear case or is left in the cooling system can freeze when the engine is removed from the water. This can cause serious damage.

r. Overheating

= DO NOT operate engine out of water even momentarily.

The engine's Water Temperature sensor is NOT a warning device.

The Raider does not have an overheat warning. The Raider will not initiate a warning to prevent powerhead damage. The EMM will only monitor and store a code in the event of an overheat.

If you suspect the engine is overheating or has overheated, STOP the engine only when it is safe.

When operating the engine, the water intakes must be completely submerged. Make sure the water intake screens are not installed upside down (ramps must be forward). If upside down, the engine will overheat. Observe proper transom height and engine trim angle.

When engine is running, the water pump indicator on the star-board side of the lower motor cover must be discharging a steady stream of water. Check the indicator often, particularly when operating in weeds, mud, or debris laden water, or at an extreme engine angle.

Cooling water check port Idle port

IF the water pump indicator stops or becomes intermittent, reduce engine speed to an idle when it is safe. Shift engine into REVERSE and operate at a slow speed for about 10 seconds. This might clear debris blocking the water intake screens.

IF the water pump indicator is still not discharging a steady stream of water, SHUT OFF the engine when it is safe. Clean the water intake screens and water pump indicator. Restart the engine and run at idle.

IF the water pump indicator still does not discharge a steady stream of water, SHUT OFF the engine when it is safe. DO NOT attempt to operate engine.

IF a steady stream of water is visible from the water pump indicator, check to see if the restrictor is installed in the end of the water hose. Without it, the engine and ECU will overheat. Continue to run engine at SLOW SPEED ONLY when it is safe until it returns to normal operating temperature.

= If the engine overheats; the cylinder and exhaust cover screws must be re-torqued.

s. Emergency Starting

! Make sure the shift lever is at NEUTRAL to prevent sudden boat movement when the engine starts.

! The engine cover is a machinery guard. Prevent injury by keeping hands, clothing, and hair clear of all moving parts. DO NOT use your hands to turn the flywheel; use recoil starter only.

! Prevent electric shock by keeping clear of the ignition coil and spark plug leads when the engine is being started or is running. Shock can cause serious personal injury under certain conditions.

If starter cord is missing or gets broken, it might not be long enough to use as an emergency starter cord. If in you need an additional rope cut cord from starter assembly.

Tie a knot to one end of cord. Place knot in the notch on top of flywheel. Wrap cord around flywheel clockwise as shown. Follow Normal Starting Procedure.

! DO NOT attempt to replace starter assembly or engine cover while engine is running.

t. Pre-Submersion Procedure

To prevent water intrusion on electronics during submersion:

1. Make sure the inside of all electrical connectors are thoroughly connected.
2. Insure the de-watering valves at the back, mid and front of the Raider is working correctly by turning valves to closed position.
3. Any time the ECU or other connectors are removed, insure they are re-connected correctly.

4. Insure oil tank if fully filled and cap tightened.

5. Connect fuel line and pump primer bulb until firm resistance is felt to fill fuel system.

During mission situations, operate as conditions require.

v. Post Submersion Procedure

After your mission, the Raider must be prepared to be returned to nonuse or prepared for your next mission.

If the RAIDER is re-submersed after your mission and it cannot be serviced, keep it submersed to avoid prolonged exposure to the atmosphere, until it can be serviced. If the Raider is brought on deck and it can't be operated or serviced, keep it submerse in fresh water, but get it prepared for your next mission as soon as possible.

If the RAIDER can be operated on deck, dewater the engine following the procedures in De-water Procedure; operate the engine for approximately five minutes at full operating temperature with fresh water. Remove the upper cover to allow the powerhead and other components to air dry. Whenever possible after use or submersion in sea water, wash entire engine with fresh water to remove salt deposits and wipe down with a dry cloth. Spray the entire powerhead with an Anti-Corrosion Spray/penetrant/lubricant or equivalent. Follow this procedure to prepare the Raider for your next mission.

4. General Maintenance

! General Safety Warnings

When replacement parts are required, use genuine

Raider parts or parts with equivalent characteristics including type, strength, and material. Failure to do so may result in product malfunction and possible injury to the operator and/or passengers.

To prevent possible eye injury, always wear SAFETY GLASSES while servicing the unit.

Always read and follow safety related precautions found on containers of hazardous substances like parts cleaners, primers, sealants, and sealant remover.

The engine cover is a machinery guard. Use caution when conducting tests on running engines. Do not wear jewelry or loose clothing. Keep hair, hands, and clothing away from rotating flywheel.

Replace any locking fastener (locknut or patch screw) if it's locking feature becomes weak. Definite resistance to tightening must be felt or locking fastener is not suitable for continued use. Replace only with authorized replacement part or equivalent.

d. Corrosion Protection

Whenever possible after use in sea water or submersion in sea water, wash entire engine with fresh water to remove salt deposits and wipe down with a dry cloth. Spray entire powerhead with a liberal coat of Anti-Corrosion Spray penetrant/lubricant or equivalent.

Though not specifically mentioned as a service procedure, Anti-Corrosion Spray or equivalent should be applied after any service repairs under the engine cover and repeated at regular intervals to protect powerhead components. Anti-Corrosion Spray leaves a thin, non-messy, transparent film that actually lifts water and moisture from metal surfaces. It protects equipment and tools that are left outdoors, even in humid coastal areas. Anti-Corrosion Spray dries out ignition systems to start wet engines and stops moisture-induced short circuits in electrical systems.

e. Optional Accessories

1) Both the 50 and 40 Horsepower can be purchased with a battery system that is enclosed under the cowling. This battery is safe underwater; can be recharged by the Raider motor once the motor is started.

2) Both the 50 and 40 Horsepower can be fitted with a dual motor single operator assembly that can quickly be attached to twin motors for a single operation. The motors come with a preset in each tiller arm and an assembly to control the throttle with a remote cable that attaches to the second motor. This controls throttle for both engines.

f. Trouble shooting

Difficult to start engine	Engine runs erratically	Boat speed loss			---	Possible Causes
●						Empty fuel tank
●	●					Incorrect connection of fuel system
●	●					Air enters fuel line
●	●					Deformed or damaged fuel pipe
●						Closed air vent on fuel tank cap
●	●					Fuel filter/fuel pump is clogged with dust.
●						Use of improper fuel
●						Incomplete forced fuel feeding by primer bulb
●	●					Poor connection in compression system
●	●					Use of non-specified spark plugs
●	●					Dirt or carbon deposits on spark plugs
●	●					No sparking or poor sparking (Failure in component of ignition system)
	●					Insufficient cooling water flow

g. Storage

Use the following procedure to properly prepare the engine for extended periods of nonuse. These steps are intended to protect the engine during storage and simplify the out of storage servicing procedure.

= Use a flushing attachment to prevent engine or water pump damage if you operate the engine on a trailer or dolly.

! When using a flushing attachment, always remove engine's propeller before starting engine to prevent accidental contact with moving propeller.

1. Follow the directions on a can of Storage Fogging Oil and spray oil through the throttle plate.

2. Stop engine and remove all spark plugs. Spray Storage Fogging Oil into the spark plug holes.

3. Pull starter to distribute the fogging oil throughout the cylinders. Install and torque the spark plugs.

! Leave spark plug leads disconnected to prevent accidental starting during storage.

1. If the engine is removed from the boat, examine all hardware you loosened or removed. Replace damaged or missing parts with genuine Raider parts or equivalent. These fasteners are made of special materials to resist weakening and rusting. Do not substitute these fasteners with nuts and bolts which look the same. Using the wrong nuts and bolts may result in sudden, unexpected loss of engine control.

2. Inspect the engine's steering, throttle, de-watering and shift systems for damage due to corrosion, aging, lack of maintenance, or abuse. Follow the maintenance and lubrication recommendations when servicing these systems.

3. Replace the engine's fuel filter.
4. Clean and inspect oil reservoir. Fill the oil tank with recommended oil to reduce or prevent condensation from forming in the tank during storage. Tank should be full prior to submersion.
5. Remove propeller and check for damage. A slightly bent propeller blade can hardly be noticed but will affect the performance of the engine. Clean the propeller shaft and lubricate with grease.
6. Drain and refill the gear case. Lubricate the engine. See Gear case Lubrication in this section.
7. Check the engine carefully. Make sure screws and nuts are tight. Replace damaged or worn parts.
8. Make sure electrical and fuel system fasteners and clamps are tight and in good condition. Failure to do so may cause electrical sparks and fuel leakage under the engine cover. Fire and explosion could occur.
9. Replace engine cover. Use touch-up paint where needed.
10. Coat all outside painted surfaces of engine with automotive wax.
11. The engine must be stored in a normal (vertical) position on the boat or on an adequate engine stand.

h. Out of Storage Service

1. Check gear case lubrication. If leakage is evident, gear case seals may need attention. See Gear case Lubrication in this section.

2. Apply a light coating of Electrical Grease to the ribbed portion of the spark plug ceramics and the opening of the spark plug covers. Connect spark plug leads. Make sure spark plug boots are not cracked or torn.

3. When engine is reattached to the boat's transom, make sure the mounting brackets, clamps, and hardware are structurally sound and in proper working condition. If mounting components use the wrong fasteners, are carelessly installed, or are defective, sudden unexpected loss of engine and boat control may result.

4. Check for evidence of water in the oil tank. Do not operate the engine if water is present in the oil tank. Serious powerhead damage can occur.

5. If the fuel hose has been disconnected, reinstall it.

i. After Submersion

After submersion or after a mission, the Raider must be prepared to be returned to nonuse or prepared for your next mission.

If the Raider is re-submersed after your mission and it cannot be serviced, keep it submersed until it can be serviced to avoid prolonged exposure to the atmosphere. If the Raider is brought on deck and it can't be operated or serviced, keep it submerse in fresh water, but get it prepared for your next mission as soon as possible.

If the Raider can be operated on deck. Follow these procedures to prepare the Raider for your next mission.

• Dewater the engine following the procedures in Dewater Procedure.
• Operate the engine for approximately five minutes at full operating temperature with fresh water.
• Whenever possible after use or submersion in sea water, wash entire engine and powerhead with fresh water to remove salt deposits, especially under the flywheel where the accumulation of deposits will build up. Wipe down with a dry cloth.
• Spray the entire powerhead with a liberal coat of Anti-Corrosion Spray penetrant/lubricant or equivalent. Spray 6 & 1 Penetrating Lubricant or equivalent under the flywheel.
• Leave the upper cover off, when possible to allow the powerhead and other components to air dry.
