5. Motor submerged in water

After taking your outboard motor out of the
water, immediately take it to your dealer.
The following are the emergency measures
to be taken for a submerged outboard
motor, if you can not take it your dealer
right away.
1. Wash the outboard motor with fresh
water to remove salt or dirt.
2. Remove the engine oil drain screw and
completely drain water and oil from the
engine.

The oil and filter may need to be
changed again after running a short

through the spark plug holes.
Pull the recoil starter several times to
circulate the oil throughout the out-
board motor.
