- Carefully lower the gearcase to access the drive shaft and its seals.
- Locate the old oil seal in the lower section of the drive shaft housing.
- Use a seal puller or flat-head screwdriver to carefully pry out the old seal without scratching the housing.
- Thoroughly clean the seal seating cavity to remove any old sealant, grease, or corrosion.
- Apply a thin layer of marine grease to the outer edge of the new seal and the inner lip.
- Position the new seal and use a suitable driver or socket to press it in evenly until it is fully seated.
- Carefully re-install the lower unit, ensuring the drive shaft, shift shaft, and water tube are correctly aligned.
- Tighten bolts to the manufacturer's specified torque.
- Reinstall the propeller and refill the gearcase with fresh marine gear lube.
- Check for leaks around the seal after running the engine.
Troubleshooting & FAQ
What are the signs of a failing oil seal?
The most common sign is milky or creamy-colored gear oil, which indicates water has mixed with the lubricant. You may also notice an oil leak around the lower unit or a recurring need to top off the gear oil.
Is this seal for the upper or lower part of the drive shaft?
This specific seal is for the lower section of the drive shaft housing, where the shaft enters the gearcase.
Will this fit my Johnson/Evinrude motor?
It fits specific Suzuki-built Johnson/Evinrude 4-stroke models (DF4/5/6). These engines use Suzuki parts. Always verify your OEM part number is 5033481 to ensure compatibility.
When should this oil seal be replaced?
It is recommended to replace the lower unit oil seals whenever the gearcase is serviced, during a water pump impeller replacement, or immediately if you detect a leak. Proactive replacement every 1-2 seasons is good practice.
