Cracked Exhaust Manifold, sealed it for less than $20.

If that doesn't work for you J-B Weld makes a high temperature and it doesn't need to be wet and I find that stuff works fantastic.

I will find out next spring how this sealant works, when put the engine on the normal operation. Wish me luck mate! Cheers!

What are we working on a boat motor or a vehicle motor ?🥴

[@n.b.p.davenport7066]

It doesn't have an oil drain plug ?

[@R4C_ENG]

Yes, there is oil drain plug. I already tried losing it but it won't turn. It's seem like it never been unscrewed for awhile. I really don't want to break it. The oil extraction pump seems easier. It just longer wait to drain it. Thanks for comment!

My guess is that it is also cracked on the inside and will destroy the motor at the most inopportune moment

[@R4C_ENG]

Thanks for the warning mate!

[@n.b.p.davenport7066]

How did it break like that ?????🥴

[@R4C_ENG]

The last person who own it forgot to winterize it. I'm just hoping that's the only thing that cracked, and nothing internal cracks. I will know until I put this boat on the normal operation.

[@DonziGT230]

That crack has absolutely nothing to do with the water in the oil, and you shouldn't run the engine with the drive tilted that high when you don't have to.
The water is probably coming from the riser gaskets which have obviously been leaking for a long time, the risers and manifolds are probably also corroded at the joint.

Thanks for the hint Mate!
