NOTICE
Discharge of oil, coolant, or other engine/drive fluids into the environment is restricted by law. Use caution not to spill oil,

the disposal or recycling of waste, and contain and dispose of fluids as required.
Checking
1. Stop the engine. Allow approximately five minutes for the oil to drain into the oil pan. The boat must be at rest in the water.
2. Inspect the condition of the spark plugs and spark plug wires. Replace as necessary. If the condition of these components is satisfactory, repeat the inspection every 100 hours or once a year,
whichever occurs first.
