CAUTION
If boat is in the water, seacock must remain 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 remain disconnected and plugged to
prevent water 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 reconnect water inlet hose before starting
engine.
NOTE: The closed cooling section of cooling system that contains coolant does not need
to be flushed. Coolant is changed at specified intervals. Refer to Maintenance Schedules.
