Engine Mounts


Brand: R&D Marine


    • Designed for marine use, accepts propeller and engine thrust in both directions.
    • Offers a fail safe design.
    • Are height adjustable.
    • Pre-loaded to reduce movement.
    • Slotted holes in base to assist in alignment.
    • Mount types to fit all applications.

    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.

  • How To Select The Engine Mount For You
    1. Engine type and number of cylinders.
    2. Type of gearbox and reduction ratio.
    3. Weight of engine and gearbox combined by weighing or manufacturers literature.
    4. Is the flywheel in conventional place between the engine and gearbox?
    5. Position of the engine mounting points.
    6. Find the center of gravity by balancing on a roller. (If possible)
    7. If the center of gravity cannot be found, assume weight distribution of 60% on rear mounts, with 40% on front mounts (if rear mount is in line with flywheel).
