Only thing I can add is that I would never run tap water through an engine. I try to always use distilled water antifreeze mix.

With the heat exchanger, raw water is drawn from a thuhull and a strainer and the raw water pump circulates that water through a heat exhanger, is injected into the mixing elbow of the exhaust hose where it mixes and goes into a lift mufler where it quiets and cools the exhaust gasses. Back to the heat exchanger: a separate pump pushes a 50:50 mix of tap water and glycol through the engine walls and through the thermostat and through the heat exchanger. The thermostat throttles the antifreeze water and not the raw water. If your engine is missing the heat exchanger, you have a raw water cooled engine, which means you do have to warm it up before inducing the antifreeze protection.

I decided to winterize my boat myself this year rather than hire someone to do it. I tried to follow the instructions in the manual for draining the engine and putting in plumber's anti freeze. I did this by loosening the intake water hose and running the motor until the anti-freeze ran out of the water exhaust. However, from what I read on the Net, it seems that I should have run the engine until it was warm so that the thermostat would open and then the antifreeze would have been circulated throughout the engine. Since I live in a harsh climate where the temperature can get to -40 degress Celsius, I am concerned about my engine freezing. The Atomic manual is completely silent about running the engine until the T-stat opens. Also, I would like to know what other owners of C&C's with Atomic 4 engines do when they winterize in terms of taking out the batteries or if they disconnect them etc. Also, what else should be done to winterize my boat other than following the Atomic 4 manual and the C&C Owners's Manual. Do most owners "fog" the engine by pouring oil into the carburetor. If so, do they use SAE HD 30 engine oil. Any advice would be very helpful. _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
