CAUTION
If boat is in the water, seacock (water inlet valve),
if so equipped, must be left closed until engine is
to be re-started, to prevent water from flowing
back into cooling system and/or boat. If boat is
not fitted with a seacock, water inlet hose must
be left disconnected and plugged (to prevent wa-
ter from flowing back into cooling system and/or
boat). As a precautionary measure, attach a tag
to the ignition switch or steering wheel of the
boat with the warning: Open seacock or recon-
nect water inlet hose before starting engine.
IMPORTANT: If a seacock is to be installed for
this purpose, valve used must have an internal
cross-sectional area equal to or greater than wa-
ter inlet hose to prevent restricting water flow
during normal operation. A 1-1/4 in. (32 mm), or
larger, brass ball valve or gate valve is recom-
mended.
1. Remove inlet hose from seapump.
NOTE: If boat is left in water, shut off seacock or plug
hose to prevent seawater from entering boat.
2. Using an adaptor, connect a garden hose from a
water tap to seapump inlet.
3. Partially open water tap (approximately 1/3 maxi-
mum). Do not use full water pressure.
4. Place the remote control lever in neutral position
and start engine.

WARNING
When flushing, be certain the area around pro-
peller is clear, and no one is standing nearby. To
avoid possible injury, remove propeller.
!
CAUTION
Do not run engine above 1500 RPM when flush-
ing. Suction created by seawater pickup pump
may collapse flushing hose, causing engine to
overheat.
!
CAUTION
Watch temperature gauge on dash to ensure that
engine does not overheat.
5. Operate engine at idle speed in neutral for 10
minutes, or until discharge water is clear. Stop
engine.
6. Shut off water tap. Remove garden hose and
adaptor from pump inlet and reconnect water in-
let hose. Be sure to tighten hose clamp securely.
IMPORTANT: If boat is in the water, do not open
water inlet valve until engine is to be restarted to
prevent contaminated water from flowing back
into engine. If boat is not fitted with a valve, leave
water inlet hose disconnected and plugged.
