The importance of engine mounts and major failure found

Ben shows one of his findings of failed engine mounts! Several tips on how to check them and setting up.

wow! a boat surveyor actually found a real problem AMAZING!

[@TheMarineSurveyorNotebookBenSu]

Yes some of us do ! 😄

Very interesting. Something you don't think to check on much.

I suspect it hasn't occurred to most people that these things take the loading resisting the engine thrust. Nice short and to the point video with good examples of what can go wrong.

Interesting. I just changed all 4 on a Yanmar 3gm. All failed. I hadn't thougt about the torque conversion and height issues. Cheers.

Thanks for the feedback 😀 it's better to shim(pack) up the whole mount than have it too high on the threads 😀

[@jackccharity]

Excellent video. All you need and nothing more!

Wow great find ! Great explanation around this issue thanks

[@dantags8565]

[@EllebogenOfficial]

Very informative. Well done.

The bottom nut on our mounts keep getting loose. Would locktite be sufficient to hold them in? The top nuts are self locking ones so stay in position, which means we simply screw the bottom nut back up and no real alignment is required.

[@TheMarineSurveyorNotebookBenSu]

Good quality lock tite may work, but consider a small lock nut under it

Why would they ever design mounts that go under a diesel engine in the water to be robust against diesel and water? Beats me...

[@wallacegrommet9343]

Thats a big challenge for any material of such small size. The world awaits your new, improved engine mount. Hurry!

Let's invent a composite plastic mount

One Danish sailor advised drilling a hole through the top steel and rubber, joining those two together with a bolt, instead of relying on about to fail galvanization and saving on replacement costs. What's your take on that method?

[@TheMarineSurveyorNotebookBenSu]

No !

[@jesperbolopetersen630]

1. You take away mass from the rubber. That changes the shore value. 2. You reduce the rubber/metal bonding surface area. 3. You add a hole, where corrosion can start. That’s the 3 reasons that pop up in my head.
