Yanmar Engine Mount Specifications


I've recently had to replace the engine mounts on my Yanmar 4JH3e on my Sabre 402. The mechanic installed 200 lb rated mounts in the rear of the engine (toward the stern) and 150 lb at the front (bow). He says he's done it this way for 20 years because the engine weights more at it's rear than the front. 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
