- Drain Oil: Locate and remove the oil drain plug. Allow all old oil to drain completely.
- Replace Oil Filter:
- Locate and remove the old oil filter.
- Apply a thin film of new engine oil to the rubber gasket of the new 16097-0008 oil filter.
- Install the new oil filter, tightening it according to your watercraft's service manual specifications (typically hand-tight plus a quarter to half turn).
- Reinstall Drain Plug: Clean the oil drain plug and reinstall it with a new washer if required. Tighten to the specified torque.
- Add New Oil: Remove the oil filler cap. Carefully pour the 4 quarts of Kawasaki KPO 10W-40 engine oil into the engine.
- Check Oil Level: Start the engine and let it run for a few minutes to circulate the oil. Shut off the engine, wait a few minutes, then check the oil level using the dipstick. Add more oil if necessary to reach the full mark.
