The R&D Marine Engine Mounts are designed specifically for the rigors of marine applications. The mounts are stiff enough to absorb forward and reverse propeller thrust yet soft enough to isolate drivetrain vibrations from the hull.
To help increase the longevity of the mounts, all steel parts are zinc plated and passivated to limit corrosion. The rubber component is covered by an oil shield to protect it from petroleum-based products.
R&D Marine mounts are preloaded based on the combined engine and transmission weight to limit engine movement. To facilitate the ease of installation, the mounts are height adjusting, and the mounting holes in the base of the mount are slotted to assist in the alignment of the drivetrain.
Available for most brands such as Yanmar, Perkins, Universal, Westerbeke, and many more.
Below are the formulas to use to determine the required pounds per engine mount.
Front Engine Mount
(W x 0.4) x 0.5 = lbs per mount
Back Engine Mount
(W x 0.6) x 0.5 = lbs per mount
W = weight of engine and gearbox
Example:
Total weight of engine and gearbox = 1,200 lbs.
Front Engine Mount
(1,200 x 0.4) x 0.5 = 240 lbs per mount
Back Engine Mount
(1,200 x 0.6) x 0.5 = 360 lbs per mount
