DRAINING INSTRUCTIONS
CAUTION
If boat is to remain in the water, seacock, if so equipped, must remain closed until engine is to be
restarted to prevent water from flowing back into seawater cooling system. If boat is not fitted with a
seacock, water inlet hose must be disconnected and plugged to prevent water from flowing into
cooling system and/or boat. As a precautionary measure, attach a tag to the ignition switch or steering
wheel with the warning that the seacock must be opened or the water inlet hose reconnected prior to
starting the engine.
IMPORTANT: Observe the following information to ensure complete draining of cooling system:
• Engine must be as level as possible.
• A wire should be repeatedly inserted into all drain holes to ensure there are no obstructions in pas-
sages.
5 Ensure engine is as level as possible to ensure complete draining of cooling system.
6 Close seacock, if so equipped, or disconnect and plug seawater inlet hose, if boat is to remain in the water.
CAUTION
Avoid damage to heat exchanger and subsequent possible engine damage. Remove all water from
heat exchanger sections. Failure to do so could cause corrosion or freeze damage to heat exchanger
water passage tubes.
