Troubleshooting & FAQ
How do I know if this bushing will fit my specific engine model?
The most reliable method is to check the Engine & Model Compatibility table. Locate your engine's brand, model, horsepower, and year. The "Notes" column often contains critical serial number ranges that are essential for confirming fitment, as manufacturers may use different parts on the same model in different production years.
What are the signs of a failing bushing?
Common symptoms include excessive vibration, unusual noises (clunking or grinding) from the drive or pivot assembly, and noticeable play or looseness in the component where the bushing is installed. A visual inspection may also reveal visible wear, cracks, or deformation of the bushing material.
What is the difference between this part and the genuine Mercury part?
Our aftermarket bushing is designed to match the fit, form, and function of the OEM equivalent. While the genuine part is sold under the Mercury brand, our part is manufactured in an ISO 9002 certified facility to meet or exceed OEM specifications using comparable materials, offering a reliable performance at a better value.
How often should this bushing be replaced?
There is no fixed replacement interval for this type of bushing. It should be inspected during regular service of your outboard or sterndrive. Replacement is recommended whenever there are signs of wear, damage, or excessive play. Factors like operating conditions (freshwater vs. saltwater) and hours of use will affect its lifespan.
Is a special tool required for installation?
Yes, a press-fit installation typically requires a hydraulic or arbor press and correctly sized drivers (sockets or specialized bushing tools) to ensure the bushing is installed straight and without damage. Attempting to hammer it in can damage the bushing or the housing.
Does this bushing require grease or lubrication upon installation?
It is generally good practice to apply a light coat of marine-grade grease or a specific lubricant recommended by the service manual to the outer surface of the bushing before pressing it in. This helps ease installation and can prevent premature wear and corrosion.
OEM vs. Aftermarket?
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.
