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 pasivated to limit corrosion. The rubber component is covered by an oil shield to protect it from petroleum based products.
R&D Marine mounts are pre-loaded based on the combined engine and transmission weight to limit engine movement. To facilitate in the ease of installation the mounts are height adjusting and the mounting holes in the base of the mount are slotted to assist in alignment of the drivetrain.
Available for most brands such as Yanmar, Perkins, Universal, Westerbeke, and many more.
