Winterizing The Heater System (In Closed-Cooled Engine Only) - CORRECT CRAFT Super Air 210 2011 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 bowl 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 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.
