High-Efficiency Vibration Damping: Specially calibrated rubber durometer and elasticity significantly dampen high-frequency engine vibration at both idle and WOT, reducing tiller/steering fatigue and hull resonance.
Oil, Fuel & Marine Corrosion Resistance: Formulated to resist degradation from gasoline, engine oil, UV exposure, and saltwater spray, preventing rubber hardening and premature cracking.
High Tensile & Tear Strength: Chemically treated steel core ensures superior bond strength with the rubber body, withstanding intense forward thrust, reverse pull, and hydrodynamic forces without separation.
Primarily compatible with Yamaha 2-stroke 40HP outboard swivel bracket and transom mount platforms (featuring the 66T model code):
Yamaha 2-Stroke 40HP Series: E40X, 40X, 40FE, 40FMH, EK40 (2-cylinder 2-stroke outboard platforms).
PREMARINE Direct Replacement: PREMARINE manufactures precision aftermarket mount dampers engineered to exact OEM 66T-44514 outer profiles, bolt hole spacings, and durometer specifications for seamless bracket integration.
PREMARINE Quality & Marine Protection: Built with upgraded fatigue-resistant rubber compounds and reinforced metal inserts, PREMARINE lower mounts offer outstanding durability and high cost-efficiency for Yamaha E40X owners.
Excessive Tiller Handle Vibration / Hull Shaking: Aged, hardened, or torn mount rubbers fail to isolate engine pulses, transferring severe vibration directly to the steering tiller and boat transom. Inspect and replace mount dampers in pairs.
Engine Bracket Play & Steering Instability: Worn or delaminated rubber mounts create excess movement between the engine casing and swivel bracket, causing steering wandering or engine misalignment under load.
Cracked, Swollen, or Degraded Rubber: Prolonged exposure to saltwater and UV light causes rubber brittleness, swelling, or crumbling. Replace deteriorated rubber mounts promptly to restore riding comfort and transom protection.
