Draining the Seawater Section of Models with Closed Cooling
NOTICE
Water trapped in the seawater section of the cooling system can cause corrosion or freeze damage. Drain the seawater
section of the cooling system immediately after operation or before any length of storage in freezing temperatures. If the boat
is in the water, keep the seacock closed until restarting the engine to prevent water from flowing back into the cooling system.
If the boat is not fitted with a seacock, leave the water inlet hose disconnected and plugged.
NOTE: As a precautionary measure, attach a tag to the key switch or steering wheel of the boat reminding the operator to open
the seacock or unplug and reconnect the water inlet hose before starting the engine.
1. If draining with the boat in the water, close the seacock (if equipped) or remove and plug the water inlet hose. If draining
with the boat out of the water, place the boat on a level surface to ensure complete draining of the system.
2. Remove the drain plug from the aft drain plug from the heat exchanger.

3. Clean out the drain hole with a stiff piece of wire until the entire system is drained.
NOTE: It may be necessary to lift or bend hoses to allow water to drain completely.
