Most of the plumbing antifreeze that is sold around here is mainly denatured alcohol, and alcohol can be hard on the rubber parts in your water pump. If you can find plumbing antifreeze based on propylene glycol it should be ok. If you can't find it, then regular engine antifreeze is designed to be rubber compatable, and I would at least get some in as far as the water pump, environment or not. For now I am using the last of my low tox propylene glycol based engine antifreeze. It is no longer for sale around here, so when that is gone I will just use regular engine antifreeze.

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
