    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.

Yanmar Engine Mount Kits

Best decision I made

I had these installed on my Yanmar 4JH3-HTE 2 years ago and I can say this was the best decision for my boat. Immediately after installing the engine mounts and starting the motor you could feel the difference in the amount vibration that gets transmitted through the hull.
At the advice of my installer (Marine Max) in Coco FL they said to buy the heavy duty mounts for both sides and not just the starboard side as recommended by the manufacturer.
With the reduced vibration and keeping the engine from shifting out of alignment with the shaft these mounts have reduced my amount of repairs and maintenance.
