Submerged Outboard Motor

A submerged outboard motor must be serviced immediately after it is recovered from the water in order to minimize corrosion.

If there is a TOHATSU outboard motor dealer nearby, take the outboard motor immediately to the dealer. If you are far from a dealer, proceed as follows:

1. Remove the engine cover, and rinse the outboard motor with fresh water to remove salt water, sand, mud, etc.

2. Drain the vapor separator as described on page 109.

3. Change the engine oil (see page 87). If there was water in the engine crankcase, or if the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour.

4. Remove the spark plugs (see page 89). Operate the starter to expel water from the engine’s cylinder.

MAINTENANCE

5. Pour a teaspoon of engine oil into each spark plug hole to lubricate the inside of the cylinders.

Reinstall the spark plugs.

If the outboard motor was running when it submerged, there may be mechanical damage, such as bent connecting rods. If the engine binds when cranked, do not attempt to run the outboard motor until it has been repaired.

MAINTENANCE

6. Install the engine cover and lock the latch securely (see page 40).

7. Attempt to start the engine.

• If the engine fails to start, remove the spark plugs, clean and dry the electrodes, then reinstall the spark plugs and attempt to start the engine again.

• If there was water in the engine crankcase, or the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour.

• If the engine starts, and no mechanical damage is evident, continue to run the engine for 1/2 hour or longer (be sure the water level is at least 100 mm (4 in) above the anticavitation plate).

8. As soon as possible, take the outboard motor to a TOHATSU outboard motor dealer for inspection and service.
