Winterizing The Heater System (In Closed-Cooled Engines Only) - CORRECT CRAFT 2011 ski nautique 200og Owner's Manual

Section 10
The raw water strainer bowl (A) remains full of water even after the
rest of the engine cooling water system is drained. To properly
winterize your boat, the strainer must be removed and emptied.
DO NOT lose the rubber O-ring (B) that seals the bowl to the cap.
Clean screen (C) if required. If the water is not removed, the bowl
can be damaged. A damaged sea strainer can cause overheating
problems during the next season.
Winterizing the Heater System (in Closed-Cooled
Engines Only)
1. Disconnect the hose connections at the engine (2 each).
2. Place one hose end into a small bucket and introduce 50 PSI
(or less) of air into the other hose end. This will force all fluid
out of the hoses and the heater core.
3. Reconnect the hoses to the engine.
