MAINTENANCE
PROCEDURE FOR FLUSHING AFTER SEA WATER USE
If the engine has been operated in saltwater, it should always be flushed with fresh water after each use before being
stored. Do not run the engine without supplying it with cooling water. Either the engine water pump will be
damaged or
the engine will be damaged from overheating. Before starting the engine, be sure to supply
water to the cooling water passages.
1. Wash the outboard motor body using fresh water.
2. Remove the engine top cowling.
3. Install the outboard motor on a test tank, or submerge the drive in water in some way, as long as the
outboard is safely and securely mounted to a solid object.
4. Fill the tank with fresh water to above the level of the anti-cavitation plate. If the freshwater level is
below the level of the anti-cavitation plate, or if the water supply is insufficient, engine seizure may
occur.
5. Run the engine at a fast idle for a few minutes in neutral position.
WARNING: Never engage forward gear if engine is running when not attached to a boat. An exposed,
spinning propeller is dangerous. Even in a tank, the engine can suddenly move when shifted
into gear causing the tank or motor to shift and expose the propeller which could result in
serious injury.
NOTE: Do not touch or remove electrical parts when starting or during operation. Keep hands, hair, and
clothes away from the flywheel and other rotating parts while the engine is running.
6. Remove the out board motor from the test tank.
7. Wipe the water off the powerhead. Install the top cowling.
8. Drain the cooling water completely out of the motor. Clean the body thoroughly.
