Or, skip that. Not sure how much lateral force the motor sees. Seems like normal is torsional due to spinning the prop. This would seem to result in one mount (left one I think) being in tension and the other in compression.

How are the rear mounts looking?

Another option would be to see if there is a mount that slides into the engine with a "drop" to it. This would result in the eyelet being say two inches below the round part that slides to the engine.

Another option would be a rework or modification of there the mount connects to the engine. Pics of this?
When I did some research on these type of mounts and shaft alignment they really don't suggest you run them so high on the threaded stud because of the lateral forces you describe. You can't see it in the pic but when you try to move the motor siedways it puts a lot force on the stud and that in turn makes the trunnion bind, making it difficult to move the motor.

The rear mounts look good, no spacer plate, and I have the trunnion sitting halfway on the threaded stud.

I'm going to inquire about different mounts today. If thats a no go my fabricater wants to build up the base of the front mount so I can drop the front trunnion an inch or so. Not sure I want to add another spacer plate like J.mccreight suggested, the one i have now seems to effect the way everthing lines up. I'd like to do away with the plate entirely.

I'm with Mccreight, maybe I am missing something, but I don't see how more spacer is going to negatively affect anything.

The spacer plate will work but I would like the mount sitting on the stringer. One reason is with the mount on the stringer I can run the stock inch and a half bolt vs a three inch. And if I go higher, now i'm looking at a four inch or better bolt.

DIM put out a call to PCM this morning and they are sending out new taller mounts. Looking foward to giving them a shot.

Hope the taller mounts work. This will be a really cool set-up if you can get it all together.

It appears you aren't using a PCM transmission? I think that would make everything work better with the alignment issues. The engine is designed to sit level, while the transmission has the angle. Now, with that said, I think taller spacers would solve your issue without harmful effects if that gives you the correct angle for the shaft.

When I got the schematic from PCM with all the dimensions it showed the PCM 1.23 gear box with the angled flange. I was pretty sure it wasn't going to fit as the overall dimension with the 1.23 box were longer so they fitted it with a 1.1

So you are using a LHR 1:1 correct? Not the RHR?

If you go higher on the mounts I would use a crossmember to tie thing together
