Disconnect the battery and adhere to all manufacturer safety precautions before starting.
Access the gear case or relevant housing where the oil seal is located.

Thoroughly clean the seal bore to remove any residual sealant, oil, or debris.
Apply a thin layer of marine grease to the outer edge of the new seal.
Gently press the new seal into position using a correctly sized seal driver or socket until it is seated evenly and flush.
Reassemble all components in the reverse order of removal.
After reassembly, run the engine and check for any leaks around the new seal.
