Troubleshooting & FAQ
How do I know if my drive shaft sleeve needs replacing?
Signs of a failing drive shaft sleeve include excessive vibration, unusual noises (grinding or whining) from the lower unit, or visible wear and tear during inspection. It can also be a source of water intrusion into the gearcase if seals are compromised.
Is this sleeve compatible with models outside the 1990-1997 range?
While this part is documented for Yamaha 40HP models from 1990–1997, it may fit other years or models that use the same OEM part number (679-45536-00-00). Always verify the part number in your engine's service manual before purchasing.
Does this part require special tools to install?
Standard marine mechanic tools are typically sufficient. However, depending on your engine's condition, you may need a bearing puller or press for removal and installation. Always refer to your service manual for specific tool recommendations.
What is the recommended replacement interval for this part?
There is no fixed replacement interval. This part is typically replaced on condition, meaning when it shows signs of wear, damage, or failure. It is good practice to inspect it whenever performing service on the lower unit or water pump.
Why is my engine vibrating after installing the new sleeve?
Vibration after installation could be due to improper alignment, an issue with another related component (like a bent drive shaft or worn bearings), or incorrect assembly. Re-check your work against the service manual or consult a professional mechanic.
What is the difference between this and the OEM part?
This is an aftermarket part designed to meet or exceed OEM specifications for fit, form, and function. It provides comparable performance and material quality to the original Yamaha part at a more accessible price point.

This listing is an aftermarket replacement (not OEM). Built to OEM-level specifications with comparable materials. Manufactured in an ISO 9002 facility, batch-inspected for consistency.
