Engine Mount Kits for Universal

Part Number: UN40584KIT

Note: Make sure your measurements match your application.



  • Engine Mount Description
    • 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 the 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 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.

Great pre-sale customer support!! The mounts were a perfect fit.

I picked these because of the stainless steel shield over the rubber parts. This, along with the coating on the base is a much better design than the Vetus mounts that were replaced. The bolts that hold the mount into the stringers were also replaced since the base is thicker than the old mounts.

Good work!

1) I chatted online with Eric Young who was excellent in helping me to identify my old mounts & provide order number for new
2) a couple days later, once I’d confirmed the old mounts were toast (threads rusted so bad they were unlikely to be adjustable for realignment) I was able to go online & easily order the correct replacements
3) AND specify rapid shipment vis UPS that actually worked across the border and up into rural Canada.
Shipment worked, mounts bolted directly in place, and alignment was easy. Lots o’ stars for PYI.

5 star all the way

great product and service, set arrived with one mount wrong weight raqnge replacement was overnighted along with prepaid return lable for wrong mount. The R&D mounts are high quality, comparing the original Yanmar mounts to the R&D mounts I'll just say is like comparing a ford pinto to ferrari

Helpful Staff

I called to ask about motor mounts and I was immediately connected to an engineer who helped answer all of my questions about the mounts compatibility and performance. I have not yet installed these mounts on my boat, but I'm confident they'll work great.
