Yanmar Engine Mount Specifications
I've recently had to replace the engine mounts on my Yanmar 4JH3e on my Sabre 402.

The Yanmar specifcations show 200 lb on the torque side of the engine and 150 lb on the opposite side.
What's your opinion? Is it possible that the specifications differ for different engines or type of boat? I've directed him to install them according to the written specifications. The boat manufacturer concurs with the Yanmar
