CAUTION:
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 trou-
ble.
Store the outboard motor in a dry, well-
ventilated place, not in direct sunlight.
Procedure
Flushing in a test tank
CAUTION:
Do not run the engine without supplying
it with cooling water. Either the engine
water pump will be damaged or the en-
gine will be damaged from overheating.
Before starting the engine, be sure to
supply water to the cooling water passag-

If the fresh water level is below the level
of the anti-cavitation plate, or if the water
supply is insufficient, engine seizure may
occur.

Keep hands, hair, and clothes away
from the flywheel and other rotating
parts while the engine is running.
