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).
