Installation Notes
- Position the sterndrive in the full tilt position and drain the gear lube completely.
- Disassemble the upper gearcase assembly according to your official service manual, keeping all parts organized.
- Carefully remove all old seals and o-rings, taking care not to score or damage the housing surfaces.
- Thoroughly clean all sealing surfaces, removing any old sealant, corrosion, or debris.
- Lubricate the new seals with a light coat of marine grease before installation.
- Press the new seals into place squarely using an appropriate seal driver or socket. Ensure they are seated fully and evenly.
- Reassemble the gearcase, torquing all bolts to the manufacturer's specified values.
- Refill the sterndrive with the correct type and amount of gear lube.
- After running the engine, check for any signs of water intrusion or oil leaks.
Troubleshooting & FAQ
How do I know if my upper gearcase seals are failing?
Common signs include milky or water-contaminated gear lube (visible on the dipstick or during a drain), oil slicks in the water behind your boat, or a noticeable drop in the gear lube level. A pressure test of the drive unit can also confirm a leak.
Is this kit compatible with dual-prop (DP) drives?
While the kit fits some DP models (like the 290DP, DP-A, DP-B, etc.) for the upper gearcase, its primary application note states it is for single propeller stern drive units. Always verify your specific model's part number requirements before ordering.
What is the difference between part numbers 876266 and 875741?
Part number 876266 superseded (replaced) the older number 875741. They are functionally identical, and this aftermarket kit is designed to replace both versions.
Do I need special tools for this installation?
Professional installation is recommended. Specialized tools such as a seal puller, seal drivers, and a torque wrench are often required to ensure the seals are removed and installed correctly without damaging the components.
What is the recommended replacement interval for these seals?
There is no fixed interval. Seals should be inspected during every annual service and replaced whenever the drive is disassembled for other service, or immediately if any signs of leaking are detected.
Can I reuse any of the old seals?
No. Once seals are removed, they can be stretched or damaged. Always use all new seals and o-rings from the kit during reassembly to ensure a proper, long-lasting repair.
