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.
