I have bought a boat with the intentions that something minor was wrong. This is my FIRST boat ever and thought I can fix it as I do know my way around engines as I rebuilt one before and work on them often.

I have changed the gaskets on the manifold and riser just to take them off and check em out.

Well I finally had time this weekend to do a pressure check. There is a crack about 3" on port side just below the head line between cyl 3 and 4. Then during the pressure test cly 2 was leaking air. There was water in the oil so the crack is all the way through. So the $#@& guy I got this from lied as they said that it has been winterized and was working great last year till this June they tried to take it out and found water in the oil..

Now the question is, as I have never had a block crack before, can this be fix at a machine shop some how, which I hope but doubt.
Would anyone have access to the block as I have called many shops local in OKC and had a few say, "Good Luck". Like your NEVER gonna find a 140 block.. hahaha.. so well I know that this is a great board and someone will come through..
Some one mentioned before about michiganmotors on ebay. I have contacted them but since its the weekend may not be working. They do carry a wide range of engines on there website www.michiganmotors.com, but most are complete and dont have that kind of money for a complete one right now.

So does anyone out there in the WWW know where I can get access to a long block GM 140hp 181cid. I am gonna try to get the block out of the boat today so I can turn it over and look at it more in detail so if you need any #'s on it let me know as I don't know what #'s that I need to post.

If no one has access to one then I guess my only other option is to part it out. Let me know

Thanks

I don't think he lied to you, that last part "they tried to take it out and found water in the oil" kind of says it all.
You ought to see this board around April when people that thought they winterized their boat found they didn't do a good enough job. Post after post of cracked blocks.

Well I believe that, I do.. But it wasn't just that they lied just about that, cause they said a professional winterized it.. I know that they can do it wrong or not complete but also they said the stern or outdrive or whatever it is.. the part that sticks out of the back of the boat off the transom.. (used to Outboards) still getting used to the terms in a inboard.. but she said it was new bought last year but didnt have any prof nor reciepts and the serial number is not readable so how is that new.. Well among other things that was said... BUT!!!

This is not why I started this thread. I can careless what they said or not I'm just in the need of a block if its feasable. I want to get my family out on the lake. I have 3 young girls and want to try to do more outdoor stuff with them instead of being couped up at home. That is one reason I bought the boat and at the price I got it if all else fails the trailer and hull is worth that..

So if anyone knows of a block I can get or use let me know.

Also I am a truck driver and can pick up from most states to save on shipping but if the price is right will still pay to be shipped if need be. I can have it shipped to one of our stores and pick it up there..

Thanks.

Check ebay,

I just put mercruiser 140 in the search function and there is at least one for sale (used). I'd try craigslist as well. They have a great assortment of stuff, you may even find one not near you that ships. G'luck!
