Engine Mounts Perkins 4-108/Westerbeke 40

[DougR]

One thing that should be considered is that when installing a close coupled V drive (as opposed to a remote V) there is an element of lift introduced into the engine that is not present in an inline installation. That is, the angle of the prop shaft is lifting up the engine in addition to pushing it forward, and this lifting force needs to be absorbed by the engine mounts on the transmission end of the package. Although the Bushings isolators are not the greatest things since sliced bread, they do make versions with an upper lip which contains the lifting thrust of the V drive.

Of course if you have a remote Walters, the V drive mounts contain the lifting force and you don't have to worry about it.

Thanks for this advice. My Walter’s V-drive is close-coupled. It makes sense that this would add lift to the transmission end of the engine. I’ll be very careful picking out the proper mount.
