I’m getting a good deal of vibration up to 1100 rpm. I’m going to calibrate the tack and recheck the motor mounts for integrity first, but I might have to replace the motor mounts. I have about 1800 hours on the engine (hull 158). I’m looking for the manufacturer of the original motor mounts. Does anyone know?

Has the damper plate ever been replaced? If not you may want to read the posts in this forum regarding replacing the damper plate. I found that was the source of our low speed vibration.

I changed the damper plate 2 yes ago.
