Engine Mounts, Couplings & Drive Plates

Proper engine mounting and power transmission coupling are essential for smooth, vibration-free operation and long drive train life. Engine mounts absorb and isolate the vibration generated by the running engine, preventing it from transferring to the hull structure where it causes noise, fatigue cracking, and crew discomfort. Flexible couplings and drive plates compensate for minor misalignment between the engine and gearbox, protecting expensive transmission components from damaging stress loads.

Luxfords supplies a comprehensive range of marine engine mounts from Vetus and flexible couplings and drive plates from Poly Flex. Vetus engine mounts are available in a wide range of load ratings and deflection characteristics to suit engines from small sailboat auxiliaries to heavy commercial diesel installations. Poly Flex flexible couplings and drive plates are precision-engineered components designed for reliable power transmission across hundreds of marine engine and gearbox combinations. Luxfords also stocks coupling bolts, alignment shims, and associated hardware to complete the installation.

Selecting the correct engine mount requires matching the mount's load rating to the engine weight (divided by the number of mounting points) and choosing the appropriate deflection characteristics for the vessel type. Flexible coupling and drive plate selection depends on the engine make and model, gearbox type, and torque rating. Luxfords maintains detailed cross-reference data for engine mounts, couplings, and drive plates covering Yanmar, Volvo Penta, Cummins, Perkins, John Deere, and many other popular marine engine brands. The Luxfords technical team can identify the correct components based on the engine and gearbox specifications.
