Troubleshooting & FAQ

Q: How do I confirm this kit fits my MerCruiser sterndrive?

A: This kit is designed for MerCruiser Alpha One Gen 2 and Bravo (1, 2, and 3) sterndrives. The best way to confirm fitment is to cross-reference the part numbers listed on this page (like 22-861150T02) with your boat's service manual or by visually comparing the old part to our product images.

Q: What are the signs that my gear lube fitting needs replacement?

A: Common signs of failure include visible gear lube leaking from the fitting area (inside the transom), a cracked or brittle plastic connector, or difficulty getting the reservoir hose to connect securely. A low or constantly dropping gear lube level in the monitor bottle is another key indicator.

Q: Is this a difficult part to install myself?

A: For those with basic mechanical skills, this is a relatively straightforward replacement. Access to the inner transom plate is the main challenge. Ensure you have a catch pan for oil and take care not to lose the small E-clip during removal or installation. If you are unsure, we recommend professional installation.

Q: My gear lube monitor alarm keeps going off. Could this part be the cause?

A: Yes, a leaking gear lube fitting is a common cause for a persistent gear lube monitor alarm. A leak at this connection allows the lube level in the reservoir bottle to drop, triggering the sensor. Inspect the fitting and hose connection carefully for any signs of oil residue.
