I have OMC Cobra 3.0 and i have the same problem. The difference is that the first owner soldered it with inox soldering. Tomorrow i’ll try with friend of me that have the same epoxy . Hope it will help.

If it's leaking out the block will it over heat engine if it's alot coming out or water just get in boat ???

@sarbjot0700 Жыл бұрын

I think you need to tighten the bolts into those holes and cut them and smoothed with the angle grinder to the block level so its make the more strength

the Alternator seems to be loose or the fixing position is worn, brazing could have been a more permanent job, good luck with it. as for me i was looking for JB weld rubber to metal fix .

Thank you. We have not yet tested it properly. In couple weeks we are planing to do so. We are planing to test everything in the water. We will share that on a video. Please follow next video. If you have any comments please share it with us. We are all learning. Thank you for your comment. Thanks again.

I've seen them fixed with silicone. JB weld will hold. there isnt much pressure in a boats cooling sytem since it is an open system. taking and leaving the thermostat out will also help to keep less pressure in the system.

No! If you have water in your oil, JB weld won't fix it. Time for a new block (yes, I know I'm replying to an old comment)

Fiberglass Jelly would work much better than JB Weld. JB weld will break down with water and heat on metal. Welding it would be the best way to fix it.

We only work on our vehicles. Our channel is about DIY. We offer ideas, and we test them. if you like to try them, it’s on your own risk. We know eventually have to change the engine, but once again it was an idea and we put it to the test. (So far it’s working) But thanks for your concern, and your comment.
