PERIODIC MAINTENANCE
Changing the Marine Gear Oil
Note: Refer to the Operation Manual
supplied with your marine gear
or sail-drive unit for service and
maintenance details.
During initial operation, the oil is quickly
contaminated due to the initial wear of
internal parts. The lubricating oil must
therefore be replaced early.

attach an oil drain pump. Drain the
marine gear oil.
2. Fill the marine gear with clean marine
gear oil. See Marine Gear Oil
Specifications on page 31.
3. Perform a trial run and check for oil
leaks.
4. After approximately 10 minutes, stop
the engine and check the oil level. Add
oil if the level is too low.
