Product Description
689-44516-00-00
Mount Damper, Upper Front, Yamaha,
For Outboard: Yamaha 20, Yamaha 25, Yamaha 30
Features:
| 1. Vibration Damping: The primary feature of this mount damper is its ability to absorb vibrations generated by the engine. It helps minimize the transmission of these vibrations to the boat, reducing noise and harshness. |
| 2. Durability: Designed to withstand harsh marine environments, the mount damper is built to last under prolonged exposure to saltwater, heat, and mechanical stress. |
| 3. Custom Fit: This damper is specifically designed for Yamaha outboard motors, ensuring a precise fit in the engine mount bracket. |
| 4. Upper Side Position: This particular mount damper is located on the upper side of the mounting system, balancing the load and ensuring stable support for the engine. |
Functions:
| 1. Vibration Absorption: It cushions the engine's vibrations to provide a smoother and more stable operation, reducing wear on other components and improving overall comfort. |
| 2. Shock Resistance: In addition to absorbing vibrations, the damper also helps absorb shocks that might occur due to sudden movements or when the boat hits rough water. |
| 3. Engine Stability: By dampening engine movement, it contributes to keeping the engine securely mounted, preventing excessive movement that could lead to misalignment or damage to other components. |
Size:
| 1. Specific to Model: The exact size of the mount damper depends on the Yamaha outboard model it is designed for. The size is specifically engineered to fit within the upper side of the motor's mounting system and varies depending on the engine's weight and power. |
| 2. Compact and Robust: Although compact in size, it is built to handle the weight and forces generated by the engine during operation. |
Maintenance Tips:
| 1. Regular Inspection: Periodically check the mount damper for signs of wear, cracking, or deformation. Since the damper is made of rubber, it may degrade over time due to exposure to saltwater, heat, and mechanical stress. |
| 2. Check for Alignment Issues: Misalignment of the engine can lead to premature wear of the damper. If the engine appears misaligned or if excessive vibration is felt, inspect the damper and other mounting components. |
| 3. Replace When Worn: If the damper shows significant wear or cracking, replace it promptly to prevent further damage to the engine or mounting system. Damaged dampers can lead to excessive engine movement and vibrations, which may affect performance. |
| 4. Grease or Lubricate Metal Parts (if applicable): If the damper includes metal components, applying a small amount of marine-grade grease or lubricant can help prevent rust and corrosion. |
| 5. Avoid Prolonged Exposure to Harsh Conditions: While the damper is designed to withstand marine environments, prolonged exposure to direct sunlight, salt, and water can accelerate wear. Store the boat and engine properly when not in use to extend the damper's life. |
Common Signs of Water Seal Damper Issues:
| 1. Excessive Vibration: If the mount damper is worn out or damaged, you may notice increased vibration while operating the engine. This can cause discomfort and reduce the longevity of other engine components. |
| 2. Engine Misalignment: A failing mount damper can lead to engine misalignment, which may cause uneven wear on the propeller, driveshaft, or other related parts. |
| 3. Noise: Increased noise or rattling sounds may indicate that the damper is no longer absorbing vibrations effectively and may need to be replaced. |
| 4. Cracking or Deformation: Visual signs of cracking, splitting, or deformation in the rubber material are clear indicators that the mount damper needs replacement. |
