Hello everyone, I'm new to the forums. I just needed to get some crazy news out. I just recently purchased a 1984 Galaxy runabout with a 2.5 OMC. The guy I bought it from neglected to mention that the block was cracked. First time on the water the entire engine compartment was filled with water within 30 min. I luckily limped it back onto the trailer in time. I got it home and bought a water muff. After running it for about 3 seconds I spotted water pouring out of 2 large cracks in the block. I pulled the intake/exhaust manifold and beheld the horror. It had a 12 inch crack at the top of the block, another 8 inch crack at the bottom, and the manifold had about a 6 inch crack. There was no water in the oil at all so I got a wild idea. I took some paint primer and hardener (from the local parts store) and mixed a a few ounces of each together. I then pushed the primer, by hand, into the cracks over and over until the primer started to "gel" up, then i covered it the rest of the way with the "gel". I put the muffs on it and got it up to operating temperature and had no leak whatsoever!!! Dry as can be!!! So far there are no other leaks and I never get any water into the boat. Sorry for the long thread but I had to let some people know of a very inexpensive technique. Let me know what you guys think.

can i be the first to say i don't like this idea? i'm sorry, just doesnt sound right.

if you have HUGE (12 in.) cracks on your block then what kind of cracks do you have on the inside?

But like i said, no water in the oil at all!!! pretty crazy i thought as well but I had nothing to lose. It runs amazingly an the oil level or color does not change at all.

I think you need an automatic bilge pump:D. Like the guy that jumped off the 10 story building said when he went past the 5th floor "so far so good"!

Good luck,hope it gets you through the rest of this summer.Over this winter I think I would look for a new engine though.It may seem to run alright now but if someone cracked a block that bad in that many places it's probably not very straight any more.

Now now, I didnt say that it wont be winterized. Trust me it will be winterized properly from now on to prevent further damage. And I will also keep you guys updated in case it fails.

I also have a question. Don't you think that a person has a legal responsibility to inform a buyer of catastrophic failure like a cracked block. He said it ran great and the boat didnt leak water.

I highly doubt this is anything more than a very temp kindafix. There is no way that is going to stay as the (what ever it was you used) is going to expand ans contract at the same rate as cast iron. it will leak again, id bet money on it.

Save your self some headache and just do it right the first time.

Quote from another member (cant remember who)
"Why is there neveer time to do it right, but always time to do it again?"

I think this thread has set a record for number of replies in the shortest time.

It was really easy to patch so it was really worth a try. As for the future I will get a new block but I will try this until it leaks. But if it doesnt leak wouldn't you be amazed. I heard a similar story of someone doing this to a car and it lasted for years with no problems. It may have been a fluke but i figured "what the heck?"

KO, seriously, a 2" crack is one thing, and I am certainly no expert, but I would think that cracks that large would almost certainly compromised the integrity of the bock. With normal heat/cool cycles... well there is no guarantee that the patch will hold, and there is potential for a big time failure.
