R & D Engine Mount Kit - 4 Engine Mounts f/Small Yanmar Engines (Yanmar*)

The R & D Engine Mount Kit is a four-mount system engineered specifically for small Yanmar marine engines, including the 1GM, 2GM, 3GM, 3YM, 3HM, and 3JH series. Designed by R & D Marine for the demanding marine environment, this engine mount kit balances vibration isolation with the structural rigidity needed to handle the forward and reverse thrust loads that propeller-driven vessels experience in real-world operation.

The engineering behind these mounts reflects decades of marine application knowledge. The elastomeric elements are tuned to absorb drivetrain vibration—noise and resonance that would otherwise transmit through the hull and fatigue structure over time—while the steel framework remains stiff enough to handle the dynamic forces of thrust reversal without deflecting excessively. All steel components are zinc-plated for corrosion resistance, critical in saltwater or freshwater environments where moisture and spray accelerate decay of unprotected fasteners and brackets.

This kit addresses a specific market: boat builders, engine repower projects, and serious boaters replacing worn original equipment who depend on Yanmar auxiliary engines for reliability. Weekend fishermen upgrading aging brackets and commercial operators running extended seasons both benefit from the improved isolation and corrosion protection. The four-mount configuration provides the support points needed for stable engine mounting across the range of small Yanmar displacement sizes, reducing vibration transmission to the hull and extending the service life of associated systems.

Engine mount selection is often overlooked until vibration or mounting failure forces replacement. The R & D Marine approach—using marine-grade materials and proven elastomer composition—recognizes that a quality mount kit is as essential to long-term engine longevity and vessel comfort as regular maintenance itself.
