Common Problems and Troubleshooting for Marine Washers
Even the best marine hardware can face issues if not maintained properly. Here are some Y/H washer troubleshooting tips for common issues:
1. Propeller Wobble or Misalignment
If you notice vibration or propeller misalignment, it could mean the washer is either installed incorrectly or severely worn. Remove the propeller and inspect the washer for deformation.
2. Rust or Corrosion Buildup
Exposure to saltwater accelerates rust formation. Inspect and replace washers showing signs of rust, as they can compromise the propeller’s stability.
3. Unusual Grinding Noises
Noises may indicate that the washer has worn thin and is no longer providing the necessary buffer between the shaft and the propeller hub.
Expert Advice and Pro Recommendations
Marine professionals unanimously recommend using OEM or OEM-compatible parts like the Y/H Washer 9.9-20HP P-8113211 YAWS. It’s important not to settle for universal washers that may not align correctly with Yamaha or Honda engines.

Detailed FAQ Section
What is the function of a thrust washer in marine engines?
The thrust washer serves as a critical interface between the propeller and the engine’s lower unit, specifically the propeller shaft. It acts as a spacer and buffer, ensuring the propeller remains correctly aligned and secured. Without a properly functioning washer, the propeller can slip, misalign, or create vibrations that damage the drive shaft and gear housing. In the case of the Y/H Washer 9.9-20HP P-8113211 YAWS, it’s specially engineered to support Yamaha and Honda outboards in the 9.9HP–20HP range, providing reliable performance under high load and speed conditions.
How often should I replace the Y/H Washer 9.9-20HP?
It’s generally recommended to inspect the washer every 100 hours of engine use or at the end of each boating season. Replacement frequency depends on usage intensity, water type (salt vs. fresh), and maintenance habits. If there are signs of corrosion, flattening, or damage, it should be replaced immediately. The cost is minimal compared to the potential damage to your propeller system.
Can I use generic washers instead of OEM like P-8113211 YAWS?
While generic washers may be less expensive, they often lack the precise engineering and corrosion-resistant materials required for optimal performance in marine environments. OEM parts like the P-8113211 YAWS are designed to exact specifications and tested in real marine conditions, ensuring perfect fit and long-term reliability. Using non-OEM alternatives could lead to improper fitting, increased wear, and voided warranties.
What are signs that the washer is failing?
Some clear signs include increased vibration while cruising, visible misalignment of the propeller, or noise during gear engagement. Upon inspection, you may notice warping, rust, or a thinner profile on the washer. These are indicators that the washer can no longer absorb thrust or keep the propeller centered effectively and should be replaced immediately.
How do I store spare marine washers safely?
Store spare washers in a dry, cool location away from salt air and moisture. Place them in sealed plastic bags with silica gel packets to absorb moisture. Avoid stacking them with heavy tools or components that could deform their shape. Also, label them clearly to ensure quick access when needed during emergency repairs.
Conclusion
The Y/H Washer 9.9-20HP P-8113211 YAWS for marine use is a small yet essential component that significantly impacts your boat’s performance and durability. Whether you’re installing a new propeller or conducting seasonal maintenance, this washer ensures proper alignment, reduced vibration, and prolonged engine life.
With expert advice, easy installation, and proper care, this marine washer offers exceptional value for both recreational and professional marine users. Don’t underestimate this part of your propulsion system—it might just save your boat from expensive repairs down the line.
