I recently acquired a boat with a fresh-water cooled Pleasurecraft 350 coupled to a SEI106 (Merc knock-off). I bought the boat as a non-runner, last-minute-before-winter fire sale purchase. Since winters is here, I just need to ensure the engine is winterized, and wrap the boat up. Although the boat did not go in the water this year and it had allegedly been properly winterized the winter prior, the owner talked about trying to get it running in his driveway and I have to assume he had water attached to the out drive.
My question is, how can I properly winterize the motor? The block has ample anti-freeze/coolant but I need to winterize the raw water system - manifolds, risers, heat exchanger, outdrive, etc. I can turn the motor over but I don't have the time to sort things out and get it running at this point.
I was thinking I could put a sump pump in a bucket of RV antifreeze and connect it to a hose going into the RW system someplace. Would this be sufficient, or could I just pull drain plugs from the heat exchanger and manifolds?
