SUBMERGED OUTBOARD MOTOR
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 dealership nearby, take the outboard motor to the dealer immediately. If you are far from a dealership, proceed as follows:
1.Remove the engine cover (p. 61), and rinse the outboard motor with fresh water to remove salt water, sand, mud, etc.
2.Drain the vapor separator as described on p. 85 – 86.
TAKING CARE OF UNEXPECTED PROBLEMS
3.Change the engine oil and oil filter as described on p. 64 – 66. 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 half an hour.
4.Remove the spark plugs (p. 68).
Operate the starter to expel water from the engine’s cylinder.
5.Put a teaspoon of engine oil into each spark plug hole to lubricate the inside of the cylinders.
Reinstall the spark plugs.
If the engine 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 engine until it has been repaired.

TAKING CARE OF UNEXPECTED PROBLEMS
6.Attempt to start the engine. Be sure the water level is at least 2 inches (5 cm) above the antiventilation plate.
Running the outboard motor without sufficient cooling water will damage the water pump and overheat the engine. If the engine fails to start, remove the spark plugs and dry them, then reinstall the spark plugs and attempt to start the engine again.
If the engine starts, and no mechanical damage is evident, continue to run the engine for a half hour or longer. Be sure the water level is at least 2 inches (5 cm) above the antiventilation plate to avoid overheating and water pump damage.
7.As soon as possible, take the outboard motor to an authorized
TOHATSU dealer for inspection and service.
