Well, I'm an idiot. I'm posting this to maybe prevent somebody else from being an idiot too. We got just a little bit sloppy last fall and didn't get the boat winterized quite soon enough. We kept thinking we would use it for a project at work, and it kept getting colder and colder. I guess by the time we finally winterized it in December the damage was done. The block is cracked in 5 places and both heads are cracked. The amazing thing is that I ran it in Florida for 20 hours in January in that condition... a testimony to the durability of the GM 350/V8. Looks like we're going to have to completely replace the engine. I can think of alot of things I'd have rather have done with the money. Ghads.   |

man that sucks! we did have a really cold nov. remember walt, its a 350, dont go blowing pointless $$$$ when you dont really have to. they are a dime a dozen. very cheap to rebuild. dont take it to some boat yard and say, "i need a new motor" ,and leave. at least not without your ky.

eshoremd - That's good advice. I'm pretty certain the engine is shot though. The guy that co-owns the boat with me is very experienced with these engines. In his teenage years and early 20's he did alot of work on 'em. He looked at the block/head damage on Tuesday and could only agree with the mechanic's assessment. One or two cracks could be welded, but this damage was too extensive. I thought these engines were supposed to have freeze-out plugs to protect you against this sort of thing, but I guess not.

Water freezes first where it's the coldest, on the surfaces of the water jacket closest to the outside. That will seal over the freeze plugs. As the water continues to freeze, it's locked inside and expands. Crack.

So the total came to $3850 to replace it with a remanufactured long-block. Since the engine was 7 years old we also had the water pump replaced and the aluminum elbows that route exhaust through the hub - they were severely corroded. And, the gimbal bearing was bad in the out-drive, which would explain some of the funny noises coming from it... also replaced. So, we're set for the next few years (hopefully) if we can remember to put antifreeze in it in the fall.  |
