Milkshake!!!

[johnnyrich10]

Hey guys I recently aquired a 1983 Chapperral 198 xlc with a mercruiser 260. it had been sitting in open storage for 2+ years un winterized. 2 of the freeze plugs where popped, so i reinstalled new ones, drained and put in new gas. started and ran it for about 5 min. no leaks ect.... i turn around for a second then look back and there was milkshake spuing out all over the engine from the carb i think. Does this automaticly mean cracked block? the engine sounded and ran fine while running and i shut it down after i noticed the milkshake? No chance it could be a head gasket ?????? :facepalm:

Thanks for any help

I'm not a seasoned marine mechanic, but unless you live on the equator, I'm guessing chances are 95% that it is cracked. You won't know till ya start digging. Good luck.

Re: Milkshake!!!

Just wondering, did you drain and replace the oil and the filter as well as the gas? It wasnt stated that you did so just wondering

Re: Milkshake!!!

even tho it sounds like a cracked engine, for a boat sitting 2 yrs plus, the oil should have been changed as you may have gotten water in there, I know if i dont change mine in the spring i get some condesation that builds up, so i just change it and all is good for the year. Just my 2 cents worth.

I recently went throug the same issues with my boat. I purchased it, changed the oil, then checked valves. When I did the oil turned into mocha coffee.
I pulled the head and found a nice little hairline crack next to a valve. $411 dollars later my engine is running smooth and has given up coffe for the time being.

Re: Milkshake!!!

Gotcha, sorry missed that part, I plan on getting in there this weekend, fingers crossed its the head, I am expecting it to be the block though with my luck. I have been doiing a little research on it but still have tons of questions. If its the block i can just replace with a chevy 350 small block? as long as I change the cam and bolt my other parts to it? I was told my exhaust manifold would prob not fit because the mercruiser 260 is a ford engine and they connect differant then chevys..... is that true?

Ayuh,... Whomever you were talkin' to, don't know what they're talkin' about...
