Forgot to drain engine block last fall

Now it boils down to budget....

Do you have insurance? you can make a claim!

If not.....

If you want to have the crack repaired.... DO NOT RUN THE MOTOR! If you run the motor you risk internal damage..... water + oil + bearingsd = disaster!

I would run a compression test on the motor and if the motor had good compression, I would pull the motor out of the boat and truely assess the damage and make sure there is only 1 crack. I would then remove the exhaust manifold to gain really good access to the crack.... clean it thoroughly with a wire brush etc.... then either bring to a welding shop (welding cast iron is a B*tch but can be done) or go get some JB WELD and smear it in the crack..... either way will work as long as the crack is only in the water jacket.

The bottom line is sometimes your lucky and its a cheap fix... sometimes your not. I hope for you its just some JB Weld and some good natured ribbing from your friends!

On a boating site, I saw this system:

A lot depends on how much work you want to do, how long you want to be boatless and how much you are willing to spend.

Remember it is a 14 year old engine. If your labor is free (you) then maybe repair is a good idea. But if you're paying for labor, I'd drop in a rebuilt engine.

Dick,sorry to hear that you found a crack,I would first make sure it is definitly cracked. You can use an angled pic to verify crack and not a casting line. If in fact it is cracked I would go with an engine assembly,my years of experience with engines those shortcut repairs don't hold up just a bandade. Welding is an option however not an easy one and you need to have plenty of room to get at the crack to weld it properly. I think when you start running the numbers an engine assembly will look pretty good. I hope I read your next post that you have insurance. Let us know.
