and start the engine. Operate engine at idle
speed in NEUTRAL gear for 10 minutes or until
discharge water is clear, then stop engine.

CAUTION
If boat is in the water, seacock (if so equipped)
must remain closed until engine is to be re-
started, to prevent contaminated water from
flowing back into cooling system. If boat is not
fitted with a seacock, water inlet hose must re-
main disconnected and plugged, to prevent wa-
ter from flowing into cooling system and/or boat.
As a precautionary measure, attach a tag to the
ignition switch or steering wheel with the warn-
ing that the seacock must be opened or the water
inlet hose reconnected prior to starting the en-
gine.
