Troubleshooting & FAQ
How do I know if this kit fits my specific Johnson/Evinrude model?
This kit is a direct replacement for OEM part number 981797. The best way to confirm fitment is to check your engine's official service or parts manual for this part number. While it fits a wide range of models, verifying the number is essential due to variations in engine production years and configurations.
What are the signs of a failing gearcase seal?
Common symptoms include a milky or creamy appearance in your gear lube (indicating water intrusion), visible oil leaking from the propeller shaft or driveshaft seals, or metal shavings on the magnetic drain plug, which can result from component wear caused by water contamination.
Is any special sealant required with these gaskets?
In most cases, these gaskets are designed to seal without additional sealant. However, always follow the recommendations in your specific service manual. Some applications may call for a light application of a non-hardening sealant on certain gaskets or surfaces.
How often should gearcase seals be replaced?
It is good practice to inspect gearcase lubricant annually or every 100 hours of use. We recommend replacing the seals and gaskets whenever the gearcase is disassembled for service, or immediately if you detect signs of leaking or water contamination.
