I installed the new mounts yesterday and they are a dramatic improvement.
Only the rear port mount was much of a challenge. When reassembling the rear mounts, there was not enough space to add the adjustment nut, lock nut a washer individually. On the starboard side I could use both hands to install them together but on the port side I ended up taping them together since I could not hold them. I had to do it again, I might try superglue.
To maintain the alignment, I made a fixture gauge from a coupling nut and bolt as I found it very difficult to get a good measurement with calipers. I also made a stubby 15/16 wrench and an open box wrench, both of which proved to be invaluable.
When doing the front mounts, the engine did not appear to move at all, but the rear mount required some adjustment to get my gauge to fit.
In slow motion I can still see a little movement at 2500 RPM, so when I have an assistant available I may try and make some additional adjustments, but overall it’s a great improvement.
Thanks again for all the help.
