1. Determine the approximate location for the sonar/GPS unit, so you

can plan how and where to route the cables for the transducer and power. This will help you make sure you have enough cable length for the desired configuration.

2. Determine the approximate location for the transducer and its cable

3. Determine the location of your battery or other power connection,

along with the power cable route.

4. Install the transducer and route the transducer cable to the so-

6. Install the power cable and route it to the sonar/GPS unit.

7. Mount the sonar/GPS unit to the bracket.

Transducer Installation These instructions will help you install your Skimmer

transducer on a transom, on a trolling motor or inside a hull. These instructions cover both single- and dual-frequency Skimmer transducers. Please read all instructions before proceeding with any installation. The smaller single-frequency Skimmers typically use a one-piece, stainless steel mounting bracket. The larger dual-frequency Skimmers typically use a two-piece, plastic mounting bracket. The trolling motor mount uses a one-piece plastic bracket with an adjustable strap.6 These are all "kick-up" mounting brackets. They help prevent damage if the transducer strikes an object while the boat is moving. If the transducer does "kick-up," the bracket can easily be pushed back into place without tools. Read these instructions carefully before attempting the installation. Determine which of the mounting positions is right for your boat. Re- member, the transducer installation is the most critical part of a sonar installation. NOTE: The following installation types also call for these recommended tools and required supplies that you must provide (supplies listed here are not included): Single-frequency transom installations Tools include: two adjustable wrenches, drill, #29 (0.136") drill bit, Phillips head screwdriver. Supplies: high quality, marine grade above- or below-waterline sealant/adhesive compound. Dual-frequency transom installations Tools: two adjustable wrenches, drill, #20 (0.161") drill bit, Phillips head screw- driver. Supplies: four, 1" long, #12 stainless steel slotted wood screws, high quality, marine grade above- or below-waterline sealant/adhesive compound. Single-frequency trolling motor installations Tools: two adjustable wrenches, Phillips head screwdriver. Supplies: plastic cable ties. Selecting a Transducer Location

1. The location must be in the water at all times, at all operating speeds.

2. The transducer must be placed in a location that has a smooth flow

of water at all times. If the transducer is not placed in a smooth flow of water, interference caused by bubbles and turbulence will show on the sonar's display in the form of random lines or dots whenever the boat is moving.7 NOTE: Some aluminum boats with strakes or ribs on the outside of the hull create large amounts of turbulence at high speed. These boats typically have large outboard motors capable of propelling the boat at speeds faster than 35 mph. Typically, a good transom location on aluminum boats is between the ribs closest to the engine.

3. The transducer should be installed with its face pointing straight

4. If the transducer is mounted on the transom, make sure it doesn't

interfere with the trailer or hauling of the boat. Also, don't mount it closer than approximately one foot from the engine's lower unit. This will prevent cavitation (bubble) interference with propeller operation.

5. If possible, route the transducer cable away from other wiring on the

boat. Electrical noise from engine wiring, bilge pumps and aerators can be displayed on the sonar's screen. Use caution when routing the trans- ducer cable around these wires. Good and poor transducer locations. CAUTION: Clamp the trans- ducer cable to transom near the transducer. This will help

revent the transducer from entering the boat if it is knocked off at high speed. Good location Good location Poor angle Poor location Good location8 How low should you go? For most situations, you should install your Skimmer transducer so that its centerline is level with the bottom of the boat hull. This will usually give you the best combination of smooth water flow and protection from bangs and bumps. Align transducer centerline with hull bottom. However, there are times when you may need to adjust the transducer slightly higher or lower. (The slots in the mounting brackets allow you to loosen the screws and slide the transducer up or down.) If you fre- quently lose bottom signal lock while running at high speed, the trans- ducer may be coming out of the water as you cross waves or wakes. Move the transducer a little lower to help prevent this. If you cruise or fish around lots of structure and cover, your transducer may be frequently kicking up from object strikes. If you wish, you may move the transducer a little higher for more protection. There are two extremes you should avoid. Never let the edge of the mounting bracket extend below the bottom of the hull. Never let the bottom – the face – of the transducer rise above the bottom of the hull. Transom Transducer Assembly And Mounting The best way to install these transducers is to loosely assemble all of the parts first, place the transducer's bracket against the transom and see if you can move the transducer so that it's parallel with the ground. Transom Hull bottom Transducer centerline9 The following instructions sometimes vary depending on the mounting bracket that came with your transducer. Single-frequency Skimmers come with a one-piece stainless steel bracket, while dual-frequency Skimmers come with a two-piece plastic mounting bracket. Use the set of instruc- tions that fits your model.

1. Assembling the bracket.

A. One-piece bracket: Press the two small plastic ratchets into the sides of the metal bracket as shown in the following illustration. Notice there are letters molded into each ratchet. Place each ratchet into the bracket with the letter "A" aligned with the dot stamped into the metal bracket. This position sets the transducer's coarse angle adjustment for a 14° transom. Most outboard and stern-drive transoms have a 14° angle. Align plastic ratchets in bracket. B. Two-piece bracket: Locate the four plastic ratchets in the trans- ducer's hardware package. Press two ratchets into the sides of the plas- tic bracket and two on either side of the transducer as shown in the fol- lowing illustrations. Notice there are letters molded into each ratchet. Place the ratchets into the bracket with the letter "A" aligned with the alignment mark molded into the bracket. Place the ratchets onto the transducer with the letter "A" aligned with the 12 o'clock position on the transducer stem. These positions set the transducer's coarse angle adjustment for a 14° transom. Most outboard and stern-drive transoms have a 14° angle. Dot10 Insert and align ratchets.

Add ratchets to bracket and transducer.

2. Aligning the transducer on the transom.

To align the transducer to the transom, side the transducer between the ratchets. Look at the transducer from the side and adjust it so that its face is parallel to the ground. The alignment letters on either side of the bracket need be the same.

nment letters Alignment positions Transducer bracket Transduce

Transducer bracket Ratchet Ratchet Transducer11 If the transducer's face isn't parallel with the ground, remove the transducer and ratchets from the bracket. Place the ratchets into the holes in the bracket with the letter "B" aligned with the dot stamped in the bracket. Reassemble the transducer and bracket and place them against the transom. Again, check to see if you can move the transducer so it's par- allel with the ground. If you can, then go to step 3A.

3. Assembling the transducer.

A. One-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the following fig- ure. Don't tighten the lock nut at this time. Position transducer mount on transom and mark mounting holes. Side view shown (left) and seen from above (right).12 Assemble transducer and bracket. B. Two-piece bracket: Once you determine the correct position for the ratchets, assemble the transducer as shown in the figure in step 2B. Don't tighten the lock nut at this time.

Assemble transducer and bracket.

4. Drilling mounting holes.

Hold the transducer and bracket assembly against the transom. The transducer should be roughly parallel to the ground. The trans- ducer's centerline should be in line with the bottom of the hull. Don't let the bracket extend below the hull! Nut Metal washer Metal washer Bolt Rubber washers Flat washe

Flat washer Nut Bolt13 Mark the center of each slot for the mounting screw pilot holes. You will drill one hole in the center of each slot. Drill the holes. For the one-piece bracket, use the #29 bit (for the #10 screws). For the two-piece bracket, use the #20 bit (for the #12 screws).

5. Attaching transducer to transom.

Both bracket types: Attach the transducer to the transom. Slide the transducer up or down until it's aligned properly with the bottom of the hull as shown in the preceding and following figures. Tighten the bracket's mounting screws, sealing them with the sealant. Adjust the transducer so that it's parallel to the ground even if you have a Deep-"vee" hull. Tighten the nut until it touches the outer washer, then add 1/4 turn. Don't over tighten the lock nut! If you do, the transducer won't "kick-up" if it strikes an object in the water. Align transducer centerline with hull bottom and attach transducer to transom. Rear view of dual-frequency Skimmer shown.

6. Route the transducer cable through or over the transom to the sonar

unit. Make sure to leave some slack in the cable at the transducer. Flat-bottom hull Dee

hull14 If possible, route the transducer cable away from other wiring on the boat. Use caution when routing the transducer cable around these wires.

Clamp the transducer cable to the transom close to the transducer. This can prevent the transducer from enter- ing the boat if it is knocked off at high speed. Caution: If you need to drill a hole in the transom to pass the connector through, the required hole size be 1". If you drill the hole, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below- waterline sealant used for the mounting screws.

7. Make a test run to determine the results. If the bottom is lost at

high speed, or if noise appears on the display, try sliding the trans- ducer bracket down. This puts the transducer deeper into the water, hopefully below the turbulence causing the noise. Don't allow the transducer bracket to go below the bottom of the hull! Trolling Motor Bracket Installation (single-frequency only)

1. Attach the optional TMB-S bracket to the transducer as shown in the

following figure, using the hardware supplied with the transducer. (Note: The internal tooth washer is supplied with the TMB-S.)

2. Slide the adjustable strap supplied with the TMB-S through the slot

in the transducer bracket and wrap it around the trolling motor. Po- sition the transducer to aim straight down when the motor is in the water. Tighten the strap securely.15 Attach motor mounting bracket to transducer.

3. Route the transducer cable alongside the trolling motor shaft. Use

plastic ties (not included) to attach the transducer cable to the troll- ing motor shaft. Make sure there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the trans- ducer is ready for use. Transducer mounted on trolling motor, side view. Transducer Orientation and Fish Arches If you do not get good fish arches on your display, it could be because the transducer is not parallel with the ground when the boat is at rest in the water or at slow trolling speeds. Bolt Internal tooth washer Nut Flat washe

Transducer angles and their effects on fish arches. If the arch slopes up – but not back down – then the front of the trans- ducer is too high and needs to be lowered. If only the back half of the arch is printed, then the nose of the transducer is angled too far down and needs to be raised. NOTE: Periodically wash the transducer's face with soap and water to remove any oil film. Oil and dirt on the face will reduce the sensitivity or may even prevent operation.

It also can use a speed sensor, but not at the same time as you are using a secondary temp sensor. To use a speed sensor and a secondary tempera- ture sensor at the same time, you will need a combination device. NOTE: If a second temp sensor is used, it must be the model TS-2U.

Recommended tools include: drill, 5/8" drill bit, 1/8" drill bit for pilot holes, screwdriver. Required supplies include: four #8 stainless steel wood screws (3/4" long), high quality, marine grade above- or below-waterline caulking compound. (If you intend to route the sensor cable through the same hole as the transducer cable, you will need a 1" (25.4 mm) drill bit instead of the 5/8" drill bit.) To install speed sensor:

1. Find a location on the boat's transom where the water flow is smooth-

Also make sure the location doesn't inter- fere with the boat's trailer. Typically, the sensor is mounted about one foot to the side of the transom's centerline.

2. Place the sensor on the transom. The bottom of the bracket should be

flush with the hull's bottom. Using the sensor as a template, mark the hull for the screws' pilot holes. Drill four 1/8" holes, one in each end of the slots.

3. Mount the sensor to the hull using #8 stainless steel wood screws

(not included). Use a high quality, marine grade above- or below- waterline caulking compound to seal the screws. Make sure the sensor is flush with the bottom of the hull and tighten the screws.

4. If the base of the transom has a radius, fill the gap between the tran-

som and the sensor with the caulking compound. This will help ensure a smooth water flow.

5. Route the sensor's cable through or over the transom to the sonar

unit. If you need to drill a hole in the transom to pass the connector through, the required hole size is 5/8". (The hole is 1" (25.4 mm) if you intend to route the sensor cable through the same hole as the transducer cable.) Caution: If you drill a hole in the transom for the cable, make sure it is located above the waterline. After installation, be sure to seal the hole with the same marine grade above- or below-waterline seal- ant used for the screws. The sensor is now ready for use. Connect the sensor to the accessory socket on the back of the unit. If you have any questions concerning the installation of the sensor contact your local boat dealer. Power Connections The unit works from a 12-volt battery system. You can attach the power cable to your boat's accessory or power buss or directly to the battery. If you use an accessory buss but have problems with electrical interference, attach the power cable directly to the battery. If the cable is not long enough, splice #18 gauge wire onto it. CAUTION: When using the unit in a saltwater environment, we strongly rec- ommend that you shut off the power supply to the power cable when the unit is not in use. When the unit is turned off but still connected to a power supply, electrolysis can occur in the power ca- ble plug. This may result in corrosion of the plug body along with the electrical contacts in the cable and the unit's power socket. In saltwater environments we recommend you connect the power cable to the auxiliary power switch included in most boat designs.23 If that results in electrical interference, or if such a switch is not available, we recommend connecting direct to the battery and in- stalling an inline switch. This will let you shut off power to the power cable when the unit is not in use. When you are not using the unit, you should always shut off power to the power cable, es- pecially when the power cable is disconnected from the unit. Power and transducer connections for the FishEasy 350C sonar unit (direct battery connection shown). If possible, keep the power cable away from other boat wiring, espe- cially the engine's wires. This will provide the best isolation from elec- trical noise. The power cable has two wires, red and black. Red is the positive lead, black is negative or ground. Make sure to attach the in- line fuse holder to the red lead as close to the power source as possible. CAUTION: Do not use this product without a 3-amp fuse wired into the power cable! Failure to use a 3-amp fuse will void your war- ranty. For corrosion protection in saltwater or high humidity environments, apply a thin layer of electrical-grade grease to each end of the fuse before installing it in the fuse holder.

Required supplies include: high quality, marine grade above- or below- waterline caulking compound, three #10 stainless steel screws. Screw length and type should be suitable for the material on which you intend to mount the bracket. Installing the bracket:

1. Mount the unit in any convenient location. Make sure there is

enough clearance for it to be tilted at angles. You should also make sure there is enough room behind the unit to attach the power/transducer cable. NOTE: Holes in the bracket’s base allow wood screw or through-bolt mounting. You may need to place a piece of plywood on the back side of thin panels to reinforce the panel and secure the mounting hardware.

2. Drill a 1" (25.4 mm) hole in the dash for the power/transducer and

accessory cables. The best location for this hole is directly under the gimbal bracket location.

3. Pass the connectors up through the hole from under the dash. You

can fill in the space around the cable with a marine caulking compound or purchase a cable hole cover from a marine dealer. Using the Quick Release Mounting Bracket These units use a quick release mounting bracket. When you run the cables through the bracket's cable slots, make sure you allow enough slack for tilting the unit and attaching the connector.

1. Align the bracket over the cable hole with the cable slots facing away

from you and fit the cable through one of the slots. Fasten the bracket to the dash using the three screw holes.25 Front view (left) and side view (right) showing dimensions of the FishEasy 350C when mounted on quick release bracket.

2. Connect the unit to power/transducer and accessory cables.

3. Hold the sonar unit vertically and slide it onto the bracket from

above. As you push down, the unit will lock into place with a distinct click. Millimeter [Inch]

It uses the optional PPP-12 portable power pack. The power pack and portable transducers expand the uses for your so- nar. The PPP-12 package includes the power pack, battery adapter and a portable transducer. The transducer can be stored inside the power pack. The PPP-12 requires eight AA alkaline batteries. Batteries are not in- cluded. To use a portable power pack, install the batteries and then attach the sonar unit to the power pack's bracket. Plug in the power/transducer cable to complete the installation. The PPP-12 has a quick-release mounting bracket built into the case. Installing the Batteries Release the latch on the front of the power pack case. Open the com- partment and install eight AA batteries into the adapter. After installing the batteries, close the case and plug the sonar unit's power cable into the socket on the power pack case. PPP-12 Portable Power Pack with FishEasy 350C stowed for transport.28 Caution: In cold weather the efficiency of dry cell batteries drops with the temperature. It is a good idea to make sure the batteries are warm before leaving home. If the batteries do lose charge, sometimes they can be restored by plac- ing them in a warm room or car interior.

Never heat the batteries over an open flame or direct hot air onto them. A fire or explosion could result. Portable Transducer Assembly Recommended tools for installation include a slotted screw driver and two adjustable wrenches.

1. Assemble the transducer and bracket as shown in the following fig-

ure. Attach the transducer to the bracket with the supplied hardware.

2. Make sure there is one washer on each side of the transducer, inside

the bracket. Slide the other washer over the end of the bolt and thread the nut onto it.

3. Screw the suction cup onto the bracket using the supplied screw and

flat washer. Tie the nylon cord through the hole in the top of the bracket. When using this transducer, tie the other end of the nylon cord to the boat. This will help prevent the loss of the transducer if it comes off the boat.

4. Clean the chosen area of the hull before attaching the suction cup.

Locate the transducer on the hull as shown in the following figure. Don't allow the bracket to extend below the hull, because water pres- sure against it can cause the suction cup to come off at speed.29 Portable transducer assembly: rear view (left) and side view (right).

5. Moisten the cup and press it onto the hull as firmly as possible. Tie

the nylon cord to the boat and route the transducer cable to the sonar unit. Your portable sonar is now ready for use. Portable transducer installed on boat transom.

Locating fish by fish symbols does have some limitations. Your sonar unit's microprocessor is powerful, but can be fooled. Some of the echoes shown as fish could be tree limbs or turtles. To see what's under your boat in maximum detail , we recommend you turn off Fish I.D. and begin learning to interpret fish arches. Tip: If you are going to be in another part of the boat or busy with an- other task, turn on Fish ID and set the audible fish alarm. An alarm will sound when a fish is detected by the unit.42 Notes43 Advanced Options & Features FishEasy 350c.
