I just winterized my boat. I think I have everything covered but I don't know if my boat has drain plugs or not. I found the ones for the regular antifreeze but no blue drain plugs for sea water. Is it possible I don't have the drain plugs? The engine is a 1998 engine.
Thanks,
Hey Club Sea Ray,
I was at the marina working on winterizing the boat. I am doing to myself to save a small fortune. The marina said because my 7.4 Mercruisers are fuel injected I should create a mix of marvel mystery oil, engine stor, and a stabilizer and run each engine for 20 minutes...
