CAUTION

  • Before beginning the running test, check that the boat with maximum capacity loading floats on the water in a proper attitude. Check the position of water surface on the driveshaft housing. If the water surface is near the bottom cowling, in high waves, water may enter the engine cylinders.
  • Incorrect outboard motor mounting height or existence of underwater object(s), such as hull bottom design, bottom surface conditions or underwater accessories, can cause water spray possibly reaching the engine through an opening of the bottom cowling during cruising. Exposing engine to such conditions for extended periods can lead to severe engine damage.

Tohatsu MX25H EverRun - CAUTION - 1

CAUTION

Mounting bolts should be installed with the bolt head at inside surface of the transom. Mounting bolts installed with the threaded end at the inside surface of the transom can cause personal injury.

Notes

1 Apply sealing agent, such as silicone sealed between the bolts and the trans-som board holes before tightening the bolts.
2 Be sure to tighten the mounting bolt nuts to the specified torque. (30Nm (13ft·lb) 3.0kgf)

Tohatsu MX25H EverRun - Notes - 1

WARNING

  • Mounting the outboard motor without following this manual can lead to unsafe conditions such as poor maneuverability, lack of control or fire.
  • Loose clamp screws and/or mounting bolts can lead to the release or displacement of the outboard motor, possibly resulting in lost of control and/or serious personal injury. Be sure that fasteners are tightened to the specified torque (30Nm (13ft·lb) 3.0kgf). Check the fasteners for tightness from time to time.
  • Be sure to use outboard mounting fasteners included in the outboard motor package or their equivalents in terms of size, material, quality and strength. Tighten fasteners to the specified torque 30Nm (13ft·lb) 3.0kgf. Test cruise to check if fasteners are tightened securely.
  • Outboard motor mounting must be performed by trained service person(s) using lift or hoist with sufficient capacity.

2. Propeller Selection

A propeller must be selected so that the engine rpm measured at wide open throttle while cruising is within the max. operating range;

25: 5150 to 5850 rpm

30: 5200 to 5800 rpm

For genuine propellers, refer to PROPELLER TABLE (p. 50).

PRE-OPERATING PREPARATIONS

Tohatsu MX25H EverRun - PRE-OPERATING PREPARATIONS - 1

DANGER

Consult an authorized dealer for details on handling of gasoline, if necessary.

Gasoline and its vapors are very flammable and can be explosive.

When carrying a fuel tank containing gasoline:

  • Close the air vent screw of fuel tank cap, or gasoline vapor will be emitted through the air vent screw, creating a fire hazard.
  • Do not smoke.

When or before refueling :

  • Stop the engine, and do not start the engine during refueling.
  • Do not smoke.
  • Be careful not to overfill fuel tank. Wipe up any spilled gasoline immediately.

When or before cleaning the gasoline tank :

  • Dismount fuel tank from the boat.
  • Place the fuel tank away from every source of ignition, such as sparks or open flames.
  • Do the work outdoors or in well ventilated area.
  • Wipe up any spilled gasoline immediately.

After cleaning gasoline tank :

  • Wipe up any spilled gasoline immediately.
  • If the fuel tank is disassembled for cleaning, reassemble carefully. Imperfect assembly may cause a fuel leak, possibly leading to fire or explosion.
  • Dispose of aged or contaminated gasoline in accordance with local regulations.

Tohatsu MX25H EverRun - Recommended gasoline types - 1

CAUTION

Use of low-quality gasoline results in a short engine life as well as starting difficulties and other engine problems.

We recommend use for Fuel stabilizer.

Use of unleaded gasoline

Use a major brand of automotive unleaded gasoline with a minimum posted octane rating of 91RON. Automotive gasoline that contain fuel injector cleaner are preferred for added internal engine cleanliness. Leaded gasoline is acceptable in areas where unleaded gasoline is not available.

Use of alcohol free gasoline

Tohatsu MX25H EverRun - Use of alcohol free gasoline - 1

CAUTION

Use of gasoline containing alcohol can cause engine starting and/or operating difficulties, wear of and damages to engine parts, and deterioration of chemical parts, which may lead to shortening of your outboard motor's life.

Note

The adverse effect caused by the alcohol content is more severe with methanol than with ethanol.

TOHATSU recommend the use of gasoline if its ethanol content is less than 10% or methanol content is less than 5% , only in case alcohol free gasoline is not available.

The alcohol component of the gasoline absorbs moisture from the air, which may disturb regular fuel flow in the fuel system, and also accelerate rusting of engine parts.

Mixing of the moisture in the engine oil can also deteriorate the properties of the lubricant.

If the use of gasoline containing alcohol is inevitable, or presence of alcohol is suspected in the gasoline, it is strongly recommended to add a filter that has water separating capability, and check the fuel system for leaks and mechanical parts for corrosion and abnormal wear more frequently.

And, in case any of such abnormality is found, discontinue the use of such gasoline and contact our dealer immediately.

Damages resulting from the use of gasolines that contain alcohol are not covered under the limited warranty.

Fuel tank capacity : 25 liters (6.6 U.S. gal)

Fuel Tank : When using a fixed fuel tank in place of genuine fuel tank, it is recommended to select a one with a structure facilitating interior cleaning.

Tohatsu MX25H EverRun - Note - 1

WARNING

Do not fill the fuel tank over capacity. The rise of gasoline temperature may cause gasoline to expand which, if overfilled, may leak through air vent screw when it is open. Leaking gasoline is a dangerous fire hazard.

Use a genuine engine oil or recommended one (TCW3). Refer to your Distributor.

Will not recommend use of other two stroke engine oil.

Tohatsu MX25H EverRun - Recommended engine oil - 1

CAUTION

Do not mix different brands of oil. Mixing different brands of oil, or different types of oil even if the brand is the same, may cause gelling, resulting in possible filter screen blockage. This could result in serious engine damage because of impaired lubrication performance.

Note

Use of engine oils that do not meet these requirements will result in reduced engine life, and other engine problems.

Add engine oil into fuel oil tank. The mixing ratio with gasoline is 1:50 (one part oil and 50 parts gasoline). Mix well by hand. The mixing ratio during break-in running is 1:25.

Mixing Ratio

Engine Oil : Gasoline
During break-in 1 :25
After break-in 1 :$0

Tohatsu MX25H EverRun - Note - 1

Engine oil - gasoline mixing procedure

For quantities of engine oil and gasoline to be pre-mixed, refer to table in previous page.

Tohatsu MX25H EverRun - Engine oil - gasoline mixing procedure - 1

CAUTION

  • Do not use other than two stroke engine oil with specified grade, or the engine may be damaged.
  • Do not use fuel prepared in other than specified mixing ratio.

  • Lack of engine oil can cause severe engine trouble such as piston seizure.

  • Excess of engine oil can shorten spark plug life, and/or cause increase of noxious exhaust.

  • When portable fuel tank is used for operation of outboard motor(s):

1 Pour engine oil into fuel tank, and then, gasoline.
2 Put cap on the tank, and close tightly.
3 Close air vent plug tightly.

Tohatsu MX25H EverRun - CAUTION - 1

WARNING

Loose cap or air vent plug can cause leak of fuel during shaking the tank.
