Troubleshooting & FAQ
How do I know if this shaft seal will fit my engine?
This shaft seal is specifically designed for marine inboard engines requiring a 45mm shaft seal and fitting a 64mm stern tube. Please measure your existing hardware to confirm these dimensions before purchasing.
What are the signs that my current shaft seal needs replacing?
Common signs of a failing shaft seal include water dripping or leaking from the stuffing box area, an unexplained increase in bilge pump activity, or visible signs of cracking, perishing, or wear on the rubber material.
How often should a shaft seal be replaced?
Replacement intervals depend heavily on usage hours, water conditions (salt vs. fresh), and regular maintenance. It is recommended to inspect the seal annually and consider replacement every 3-5 years or at the first sign of wear or leakage.
