Installation Notes
- Disconnect the vessel's battery and follow all safety precautions before beginning work on the sterndrive.
- Access the bell housing area where the shift shaft mechanism is located. Partial disassembly of the drive unit may be required.
- Carefully remove the old shift shaft seals and bushings. Use an appropriate removal tool to avoid scoring the housing.
- Thoroughly clean the bushing bores in the housing to remove corrosion, debris, and old sealant.
- Using a suitable press or bushing driver, carefully press the new bushings into place until fully seated. Ensure that they remain straight during installation.
- Install the new seals. Apply only a light coat of suitable marine-grade grease to the sealing lips to aid installation and protect the shaft.
- Reassemble the shift mechanism and all other components in the reverse order of removal.
- Test the shifting action to ensure that it is smooth and engages correctly before returning the vessel to service.
Troubleshooting & FAQ
Will this kit fit my MerCruiser Alpha One Gen I drive?
No. This kit is intended for Alpha One Gen II sterndrives with serial number F094775 and up. It is not listed for Alpha One Gen I drives.
What are the signs that my shift shaft bushings need replacement?
Possible symptoms include difficulty shifting into or out of gear, a stiff or binding shift lever, or visible water intrusion around the shift shaft area in the bell housing. These symptoms can have multiple causes, so inspect the complete shift mechanism before replacing parts.
How often should these bushings be replaced?
There is no fixed service interval stated for this replacement kit. Inspect the bushings during major sterndrive service or whenever shifting problems occur. Wear can be accelerated by frequent use and saltwater exposure.
Is any special tool required for installation?
A suitable bushing driver or press is highly recommended for proper installation. Hammering the bushings directly can damage the bushings or the housing and may result in an incorrect fit.
Is this an OEM part?
No. This is an aftermarket replacement kit, not an original Mercury/MerCruiser component. It is intended to provide replacement fit and function for the listed application.
How fast is shipping?
Typical transit is 5–15 days. Standard shipping is free, with expedited options available at checkout where applicable.
What is the warranty and return policy?
Warranty coverage and return eligibility follow the applicable retailer's current terms. Contact customer support with your order details if you need assistance with a product issue or return.
