- Ensure the engine is off, cool, and disconnected from the power source.
- Access the seal by removing any necessary engine covers or components.
- Carefully extract the old, worn seal using an appropriate seal puller, taking care not to scratch the housing.
- Thoroughly clean the seal bore and shaft surface, removing any old residue or corrosion.
- Lightly lubricate the inner and outer surfaces of the new seal with the engine-appropriate grease or oil.
- Position the new seal and press it in evenly using a seal driver or a socket of the correct diameter. Ensure it is seated at the correct depth.
- Reassemble all components in the reverse order of disassembly.
- After reassembly, run the engine and check for any leaks around the new seal.
Troubleshooting & FAQ
How do I know if this oil seal will fit my specific outboard model?
This seal is designed for Yamaha 300–350 HP 4-Stroke models manufactured between 2005 and 2010. To ensure a perfect match, cross-reference the OEM part number 93101-12M70-00 and consult our compatibility table. When in doubt, compare it visually with your old part.
What are the signs of a failing oil seal?
The most common sign of a bad seal is a visible oil leak from the engine area where the seal is located. Other symptoms can include a noticeable drop in oil levels without other visible leaks, or smoke from the engine if oil is dripping onto hot components.
How often should this seal be replaced?
There is no fixed replacement interval for this seal. It should be replaced whenever it shows signs of leaking, or as a preventative measure during major engine overhauls or related repairs.
Can I install this oil seal myself?
Installation requires accessing internal engine components. While it is possible for an experienced DIY mechanic, we strongly recommend professional installation to prevent potential engine damage and ensure the seal is seated correctly.
