Changing Oil and Filter

Refer to the Maintenance Schedule for the change interval. Engine oil should be changed before placing the boat in storage.
IMPORTANT: Change engine oil when the engine is warm from operation. Warm oil flows more freely, carrying away more
impurities. Use only recommended engine oil (refer to Specifications).
