It would be enjoyable if you'd take (and post) pictures of replacing coupler without pulling engine

I really appreciate the input!
How is that possible? You have to take the bell housing off which holds up the back of the engine.

I am hoping to be able to move the engine forward and support it otherwise. Is this even feasible?

I just have no way to actually pull the engine out of the boat.

Well upon further inspection and reflection it seems as though I do not thrive on a challenge as much as I did many years ago. So I will let the professionals have all the fun on this change out.
Off to find a good mechanic.

Thanks for all the help!

IMO if you aren't able to r&r motor yourself ,you should find a reputable shop to be using in your area . IF the coupler is your problem, replacing it is not difficult, but it requires engine r&r.
I was joking about you taking pictures of doing it without pulling motor

I agree, I've had a friend throw parts at problems only to find out it was something else. Also a coupler that's greased and aligned should last almost indefinitely.

When throttling up are both engines at the same RPM? Engines out of sync will cause a viberation.

Also is it possible that maybe you have a intermittent engine/s issue seemingly like its coming from the driveline? Vapor lock, fuel, ignition, etc.

Find a good tree limb and use a chain fall or something. Forklifts, back hoe, skid loader all work pretty well. I've done the tree limb deal alot. Motor doesn't have to come all the way out but up and forward a little.
