David, I believe my vibration is also due to original Motor Mounts as well on my 1983 - 37. Any other tips on the replacing? I asked a mechanic and he said they needed a special tool to raise the engine? Also No idea how I am getting to back ones with out removing fuel tank Which is nice new plastic type but placed in starboard lazzarette making all entry to aft section rudder and motor Difficult Thanks!

It’s happiest around 2200 RPM at roughly 6 knots. Anything more than that it sounds like the hull is shaking apart. Not a lot of sound deadening in general with that diesel, but it gets pretty loud at higher RPMs. Since I replaced the shaft, cutlass bearing, installed a dripless shaft seal when purchased 4 years ago, vibration is likely motor mounts which are probably original.
