Troubleshooting & FAQ

How do I know if this bearing is right for my engine?

Verify that your engine is a Yamaha V6 150-225 HP model from 1984–Current with a 2.6L displacement. The most reliable method is to cross-reference the OEM part number 93315-425V3-00 with your engine's service manual or parts diagram.

What are the signs of a failing forward gear bearing?

Common symptoms include a grinding or whining noise from the lower unit (especially when in forward gear), excessive metal shavings on the magnetic drain plug, and difficulty or roughness when shifting into gear.

When should this bearing be replaced?

There is no fixed replacement interval. This bearing should be inspected during any major lower unit service and replaced if you notice any signs of wear, such as pitting, rust, noise when spinning, or excessive play.

Are special tools needed for installation?

Yes, professional installation is recommended. Proper removal of the old bearing and installation of the new one requires a hydraulic press and specific bearing pullers and drivers to avoid damaging the bearing or gearcase housing.
