Troubleshooting & FAQ
How do I know if my saildrive seals need replacing?
Common signs of failing seals include water intrusion into the saildrive oil (making it appear milky or cloudy), a visible oil sheen on the water's surface around the drive leg, or a consistent loss of oil level.
Is this kit compatible with my specific engine model year?
This kit is designed for the specified saildrive models (120S, 130S, 150S) and their associated engine series. Please review the compatibility table to confirm if your specific engine model is listed. If it appears in the table, the kit is a confirmed fit.
What is the recommended replacement interval for these seals?
It is generally recommended to replace saildrive seals as a preventative measure whenever the main saildrive diaphragm (bellows) is changed, which is typically every 5 to 7 years, depending on manufacturer recommendations and usage.
Does this kit include the large main rubber diaphragm/bellows?
No, this is a sealing ring kit for the drive leg mechanism. The large rubber hull diaphragm (also known as a bellows) is a separate component and must be purchased independently.
