About the rear mount - engine bracket to transome plate

[Glaspar_Fan]

Can someone explain how the rear engine mounts (bolt, washer, sleeve, fiber washer, spiral lock washer and nylock nut) work? The diagram shows the assembly, but where are the forces applied that bind the transome plate and engine ("bell housing") bracket? Not sure it makes sense though and I want to get it right, just in case there is an issue with the pictures.

From the diagrams in the manual and online, it appears to me that the nut is held captive in a pocket in the transome plate and that as the bolt is tightened the nut comes up to bear directly on the transome plate. The engine bracket is forced down onto the fiber washer as the bolt head bears directly on the steel washer and force is transmitted through the sleeve to the engine bracket.

But how is any force applied to that spiral lock washer? And is all the binding force really transmitted via that sleeve directly to an aluminum bracket? Or does the whole works actually float around the sleeve somehow?

I'm clearly missing something.

Thank you,

John

Ayuh,... It's steel on steel inside the rubber mounts,....

I use maskin' tape to hold the lower nuts in place, start the bolt, 'n drive it home,...

Assuming you have the parts in place correctly the washer goes on the bolt, the sleeve, the sleeve contacts the inner part of the rear mount, to the doublewound washer underneath ,all that tightens with the nut.
The rear of the engine is supported buy the rubber of the mount,does not rest on the transom plate.
The washer you put on the bolt prevents the whole engine from getting off the mount

Well, I think the joke is on me. The talk of rubber in that mount got me thinking and looking at other pictures. Looks like there is at least one rubber donut on each side that is missing. Time to shop for the mounts. Looks like the guy that replaced the engine the last time didn't do the mounts right.

Just to verify though, the engine mount does rest on the large fiber washer which rests on the transom plate, right?

Thanks,

John
