Ok I took a chance and bought a 1984 Four Winns Marquise 170 with a Mercruiser 3.0. Boat was trash when I got it. I'm a professional firefighter and decided to take it to the fire station and have a down time project. Gutted hull out rebuilt stringers all new floor. Total gut job. Started doing the upholstery and all that. Motor was not running when I purchased last year but a little work on fuel pump and carb all was well. Hence why I started to do the restore process. Ran it out of water a few times last summer and all ran fine. Been working on it all summer this year on cosmetic things and decided I better winterize. Started the motor and it ran like crap. Would not idle at all. Engine would run at higher rpm but ran very rough at low idle and would die. This is all done out of water on muffs btw. Messed with it again today and saw it was steaming or white smoke from exhaust. Long story short it is steam...I found a cracked exhaust manifold. I'm guessing last year when I winterized I did not get all water out of manifold due to chunks of rust clogging drain hole. Let me add this is my first dabble into restoring an old inboard boat. Cosmetically she is coming along nicely. But this manifold issue has me worried.
Should I repair this manifold by braising or just buy a new one. It appears that oil is a little milky as well. I would say that water has leaked into the valves. Oil level did not rise but it definately have some water in it.
I have no idea how long this boat had been setting prior to me purchasing but it had a 2014 sticker on it. I'm guessing thermostat and such may be bad because it looks rather rusty inside when hoses are removed.
Any insight on things I might need to look for that might be wrong besides the cracked manifold. I'm worried if I didnt cause it from leaving some water in it from last year what may have caused it then. I dont want to replace and the same thing happen again. Thanks in advance to any help I recieve.
