Installation Notes
- Ensure the engine is off and the battery is disconnected before starting work.
- Drain the gearcase lubricant completely from the lower unit.
- Carefully disassemble the lower unit to access the forward gear assembly. Refer to your service manual for model-specific instructions.
- Remove the propeller shaft and gear assembly to expose the old forward gear bearing.
- Use an appropriate bearing puller to safely extract the worn bearing from its housing.
- Thoroughly clean the bearing seat and surrounding area, ensuring it is free of debris and old grease.
- Press the new bearing into place using a suitable bearing driver or press. Ensure it is seated evenly and fully.
- Lubricate the new bearing and assembly with marine-grade grease.
- Reassemble the gearcase components in the reverse order of disassembly.
- Refill the lower unit with the correct type and amount of gear lubricant.
- Check for leaks and test the engine in a safe environment before full operation.
Troubleshooting & FAQ
What are the signs of a bad forward gear bearing?
Common symptoms of a failing forward gear bearing include a grinding or whining noise from the lower unit (especially when in forward gear), excessive vibration, or the presence of metal shavings in the gear oil during a change. Difficulty shifting into gear can also be an indicator.
Where exactly is this bearing installed?
This tapered roller bearing is located in the lower unit (gearcase) of the outboard motor and supports the forward gear on the propeller shaft assembly.
Will this fit my Yamaha 115 HP motor?
No, this particular bearing is designed for Yamaha engines in the 50 HP to 100 HP range. Please consult your service manual or a parts diagram for the correct bearing part number for a 115 HP engine.
Can I replace this bearing myself?
While possible for experienced mechanics with the right tools (like a bearing press and pullers), replacing internal gearcase components is a complex job. We recommend professional installation to ensure proper seating, alignment, and long-term reliability.
What is the difference between this bearing and the original Yamaha part?
This is an aftermarket part designed to meet or exceed OEM specifications for fit, form, and function. It is made from high-quality GCr15 chrome steel and offers comparable performance and durability to the original at a better value.
Is any special maintenance required after installation?
No special maintenance is needed for the bearing itself, but you should adhere to your outboard's recommended service schedule. Regularly changing the gearcase lubricant is the most important factor in maximizing its service life.
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.
