Changing Oil and Filter
Refer to 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).
Oil Removal with Drain Pump
1. Loosen the oil filter to vent the system.
2. Remove the dipstick.
3. Install the oil drain pump onto the dipstick tube.

crankcase is empty.
5. Remove the pump.
6. Install the dipstick.
Changing the Oil Filter
NOTE: Keep oil off the exhaust manifold and also the serpentine belt.
1. Remove and discard the oil filter. If any oil escapes from the oil filter, it will exit the oil drain slot. Place a container below
the oil drain slot to catch any oil.

2. Coat the sealing ring on the new filter with engine oil.
3. Install and tighten the oil filter securely following the filter manufacturer's instructions. Do not overtighten.
4. Remove the oil fill cap.
5. Use the dipstick to determine the amount of engine oil required. Replace the dipstick.
6. Add the required amount of the recommended oil to bring the level up to the bottom of the OK range on the dipstick.
7. With the boat at rest in the water, repeat steps 5 and 6 if necessary.
NOTE: Adding 0.95 L (1 US qt) of engine oil raises the level from the bottom of the operating range to the top of the
operating range.
