After operation in muddy, brackish, or salt
water, you should flush the water passages and
motor surface with clean, fresh water. If you do
not flush the water passages, salt can corrode
the motor and shorten its life.
1. Make sure that the motor is stopped.
2. Shift the motor into "NEUTRAL".
3. Remove the propeller from the motor. Refer
to the PROPELLER SELECTION AND
INSTALLATION section.
4. Install the motor on a large container such
as an empty 55 gallon drum.
5. Fill the container with clean, fresh water as
illustrated.
6. Start the motor and let it idle for about five
minutes. This will clean the salt water out of
the cooling system.
7. Shut off the motor. Remove the motor from
the container and maintain motor in a verti-
cal position until the engine has drained
completely. Reinstall the propeller as out-
lined in the PROPELLER SELECTION AND
INSTALLATION section.
8. Clean the motor surface and apply a coat of
automotive wax on the external finish of the
motor.

2. Remove the flush plug and install the flush-
ing attachment 1.
3. Connect a garden hose to the flushing
attachment.
4. Turn on the water to obtain a good water
flow. Flush the engine for about five minutes.
5. Turn off the water.
6. Remove the hose and flushing attachment
then reinstall the plug into the flushing port.
7. Leave the motor in a vertical position until
the engine is drained completely.

cal position" instructions.
