Dealer winerized my 3.0 Mercruiser and I just tried Spring launch. I hopefully reconnected all hoses, but still have water coming from somewhere - I suspect the single point drain system. The maual is not much help. I could take in back to dealer, but as busy as they are, may not see my boat till Labor Day. Am I missing something about this system?<br /><br />Thanks

My 3.0 only has two drain plugs. One on the bottom of the exhaust manifold, and one on the engine block.<br /><br />Can you see where the water is leaking from?

I may be missing something here, but why don't you just start it up and have a look at the engine and locate the leak instead of guessing where the water might be coming from?
