MAINTENANCE

STORING THE OUTBOARD MOTOR

NOTE: Place a towel or something similar under the outboard motor to protect it from damage.

When storing your outboard motor for prolonged periods of time (2 months or longer), several important

procedures must be performed to prevent excessive damage.

NOTE: Cooling system flushing is essential to prevent the cooling system from clogging up with salt sand,

or dirt. In addition, fogging / lubricating of the engine is mandatory to prevent excessive engine

damage due to rust. Perform the flushing and fogging at the same time.

• To prevent problems which can be caused by oil entering the cylinder from the sump, keep the outboard

motor in the attitude shown when transporting and storing it. If storing or transporting the outboard motor

on its side (not upright), put it on a cushion after draining the engine oil.

• Do not place the outboard motor on its side before the cooling water has drained from it completely,

otherwise water may enter the cylinder through the exhaust port and cause engine trouble.

• Store the outboard motor in a dry, well ventilated place, not in direct sunlight.

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 cover.

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. Install the top cover.

8. Drain the cooling water completely out of the motor. Clean the body thoroughly.
