Changing Oil and Filter

Refer to the Maintenance Schedule for the change interval. You should change the engine oil before placing the boat in
storage.
IMPORTANT: Change the engine oil when the engine is warm from operation. Warm oil flows more freely, carrying away more
impurities. Use only the recommended engine oil. Refer to Specifications.
1. Start and run the engine until normal operating temperature is achieved.
2. Stop the engine and wait approximately five minutes for the oil to drain into the oil pan.
3. Drain the oil from the engine into a suitable container. Dispose of all waste oil as directed by local authorities.
4. Place a suitable container under the oil filter housing to contain any oil leakage that may occur. Use an appropriate socket
to loosen the oil filter protective cap.
5. Remove the protective cap and filter element.
