I have an Atomic 4. Love it, by the way.
Yes, run motor until up to normal operating temp before introducing anti-freeze. Otherwise you are just winterizing the manifold, silencer, pump and riser. I fog with a spray can of engine fog and then take out each spark plug and spray the fogging oil into the top of the cylinder through the spark plug hole. I then crank the engine briefly and re-install the plugs. I change the oil while it is still warm I make sure the batteries are fully charged and full of acid, disconnect them and leave them in the boat. Charged batteries don’t mind the cold at all. I also change my fuel filters while I’m in there but that is just me. I like to set up for turn-key starting in the spring. This all assumes you run with treated gas Burt From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Bernard Toews via CnC-List Sent: Saturday, November 01, 2014 2:51 PM To: cnc-list@cnc-list.com Subject: Stus-List Winterizing my 1979 C&C 34 I own a 1979 34 C&C which has an Atomic 4 engine. 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.
