Changing Oil and Filter
See 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 the
Specifications section).
Easy Engine Oil Drain System
NOTE: The boat must be out of water to perform this procedure.
1. Loosen the oil filter to vent the system.
2. Allow sufficient time for the oil to drain from the filter down into the engine block.
3. Remove the bilge drain plug.
