damaged.
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.
3. Remove the spark plugs, and com-
pletely drain the water from the engine
by pulling recoil starter several times.
Replace oil filter and oil to the correct
level.
The oil and filter may need to be
changed again after running a short
period to get all moisture completely
out of the crankcase.
4. Inject a sufficient amount of engine oil
through the spark plug holes.
Pull the recoil starter rope several times
to circulate the oil throughout the out-
board motor.
