OK guys, I have owned a checkmate with a Merc 4.3 Alpha 1, I have always drained all the water from the block, and manifolds and never had a problem, yes did lower unit service, fog, but just drained the block and manifolds. I keep it in an unheated garage Southern Wisconsin gets to 20-30 below maybe 7-15 days in the winter...
Bought a used Liberator, has GM? 350 Cobra (did not know GM made a cobra engine, but seller swears is) with OMC outdrive. Seller had bought for 6 months, bought from neighbor. He and a mechanic friend winterized it I was told.
I took it home, and opened the starboard manifold, was plugged with an inch of sand, broke through it, and light pink water came out, smelled like anti freeze, RV type, but looked a little weak. I saved some, and bought an antifreeze tester. Only one ball floated, thats 20 degrees above 0....not good, took the sample, put it in my freezer, in three hours was slush, after overnight was semi solid ice...emailed seller, said his friend used 50/50 rv antifreeze in a garbage can, sucked it up till thermostat opened and antifreeze coming out of exhaust about 5-10 minutes, then fogged and shut off.
I took sample from block, same results....should I just drain the block and manifolds and be done? Or should I pull all hoses and add more RV antifreeze after draining until it come out then close cocks, and manifold drains?
Yes I know to make sure if I drain to push a wire into drains to make sure they are not blocked....
Help me it is 25 degrees right now, winter is coming....
