2005 Tahoe 4.3L V-6 190HP<br /><br />I started up the boat today and ran it for about 30 minutes on the muffs. The engine ran good, but I did notice water dripping from under the port side exhaust manifold. Specificially, it seems to be leaking from manifold around where the hose connection screws in. There is a blue plasitc drain plug coming out of the bottom, but it seems to be wet above that.<br /><br />We did hit 9 degrees, so it got plenty cold enough to freeze...<br /><br />Any ideas? What should I have done differently? Known issues on these engines?<br /><br /><br />I winterized the boat last fall before hitting freezing temps. I followed the procedure below.<br />1. Pulled all blue plastic drain plugs from engine and exhaust manifolds. I would say a gallon or so of water drained out.<br />2. Replaced plugs and backfilled from the water pump area w/ 100% Prestone Anti-Freeze. I wanted to be sure that even if I ddin't get all the water out there would be an antifreeze mixture in there.<br />3. Prior to draining the engine, I did fog it and it had treated fresh gas in it.
