Product Description
679-44555-00-00
Mount Damper, Lower Side, Yamaha,
For Outboard: Yamaha 40, Yamaha FT50, Yamaha F45, Yamaha F50
Features:
| 1. Vibration Dampening: The primary feature of the lower side mount damper is its ability to reduce vibrations that are generated by the outboard motor during operation. It isolates these vibrations from the boat's transom, improving overall comfort. |
| 2. Durability: Built to withstand the rigors of marine environments, the damper is designed to resist wear and tear caused by continuous engine operation, as well as exposure to saltwater, oil, and other harsh elements. |
| 3. Shock Absorption: In addition to vibration damping, it provides shock absorption to protect the engine and mounting assembly from sudden jolts caused by waves or rapid changes in throttle. |
Functions:
| 1. Reduces Engine Vibration: The main function of the lower side mount damper is to reduce the transmission of vibrations from the engine to the boat, ensuring smoother and quieter operation. |
| 2. Improves Comfort: By minimizing engine noise and vibrations, it enhances the comfort of the ride for boat passengers, especially at higher speeds or under heavy loads. |
| 3. Protects the Mounting System: The damper also plays a crucial role in protecting the engine's mounting system and the boat's transom from excessive wear due to constant vibrations and shocks. |
| 4. Enhances Stability: By stabilizing the engine's movements, it helps maintain better control and performance, especially in rough water conditions or during sudden maneuvers. |
The size of the lower side mount damper varies depending on the specific Yamaha outboard motor model and horsepower rating. Key dimensions include:
| 1. :Diameter: The damper's diameter typically ranges from 2 to 4 inches (50 to 100 mm), depending on the engine size and mount configuration. |
| 2. Thickness: The thickness of the rubber or urethane material usually falls between 0.5 to 1 inch (12 to 25 mm), which provides sufficient cushioning for effective vibration isolation. |
| 3. Custom Fit: These dampers are designed to fit specific Yamaha outboard models, so it's important to use the correct size and type for your particular engine. |
Maintenance Tips:
| 1. Regular Inspection: Periodically inspect the lower side mount damper for signs of wear, cracking, or deterioration. Over time, exposure to the elements can cause the rubber material to degrade, reducing its effectiveness. |
| 2. Check for Loose Mounts: Ensure that the damper is securely fastened to the motor's mounting assembly. Loose or damaged dampers can result in increased vibrations or noise, leading to potential damage to the engine or transom. |
| 3. Clean Regularly: After each use, particularly in saltwater, rinse the damper and the surrounding area with fresh water to remove salt, dirt, and debris. Salt buildup can accelerate the degradation of rubber components. |
| 4. Replace When Worn: If you notice excessive vibration, noise, or visible damage to the damper, it should be replaced immediately to prevent further damage to the engine mounting system or transom. |
| 5. Inspect Related Components: In addition to checking the damper itself, inspect the entire mounting assembly, including bolts, brackets, and other rubber components, to ensure that everything is in good condition. |
| 6. Avoid Excessive Shock Loads: While the damper is designed to absorb shocks, excessive force from rough water or sudden stops can damage it. Avoid overloading the boat and adjust your speed in choppy conditions to reduce stress on the damper. |
Common Signs of Mount Damper Issues:
| 1. Increased Vibration or Noise: If you start to feel more vibration or hear unusual noises while operating the motor, it could indicate that the lower side mount damper is worn out or damaged. |
| 2. Visible Cracks or Tears: Upon visual inspection, if you see cracks, splits, or tears in the rubber part of the damper, it means it has likely reached the end of its lifespan and should be replaced. |
| 3. Loose or Shaky Engine Mount: A failing damper may cause the engine to feel loose or unsteady, especially when accelerating or cruising at high speeds. |
| 4. Misaligned Mounting Components: If the motor mount appears misaligned, or you notice uneven wear, it could be due to a compromised damper that no longer cushions the engine properly. |
