Troubleshooting & FAQ
How do I know if this oil seal fits my specific outboard model?
The surest way is to match your original part number to one listed in our Part Number Matrix. You can also consult the Engine & Model Compatibility table to find your model and year range. When in doubt, compare the dimensions (12 × 24 × 4.5 mm) to your old seal.
What are common signs that my gearcase oil seal is failing?
The most common indicators are visible gear oil leaking from around the propeller shaft area or discovering milky, water-contaminated oil during a gear lube change. Water intrusion can cause severe gearcase damage if not addressed.
What does the "SC" profile type mean?
"SC" refers to a standard single-lip seal design that includes a garter spring. The spring provides consistent radial force on the shaft to create a reliable seal, compensating for minor wear and thermal expansion. It is a common and effective design for marine applications.
What's the recommended replacement interval for a gearcase oil seal?
There is no fixed interval, but seals should be inspected for leaks during every gear lube service. It is highly recommended to replace the oil seals whenever the gearcase is disassembled for other service, such as water pump replacement or bearing work, as they are a critical and inexpensive wear item.
