Checking and Filling
NOTICE
Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil,
coolant, or other fluids into the environment when using or servicing your boat. Be aware of the local restrictions governing
the disposal or recycling of waste, and contain and dispose of fluids as required.
IMPORTANT: Always use the dipstick to determine the exact quantity of oil or fluid required.
1. Stop the engine and allow the oil to drain into the oil pan for approximately five minutes with the boat at rest in the water.
2. Remove the dipstick, wipe clean, and install fully into the dipstick tube. Wait 60 seconds to allow trapped air to vent.
NOTE: Install the dipstick with the oil level indication marks facing the rear of the engine.
3. Remove the dipstick and observe the oil level.
4. If the level is below the add mark, remove the oil fill cap and add the specified oil to bring the level up to the OK range on
the dipstick. Recheck the oil level as you fill the system.
IMPORTANT: Do not overfill the engine with oil.
