1. Place the outboard in either the operating position (vertical) or in a tilted position.
2. Remove propeller. Refer to Propeller Replacement.
3. Thread a water hose into the rear fitting. Partially open the water tap (1/2 maximum). Do not open the water
tap all the way, as this allows a high pressure flow of water.
IMPORTANT: Do not run engine above idle when flushing.
4. Shift outboard into neutral. Start the engine and flush the cooling system for at least 5 minutes. Keep engine
speed at idle.
5. Stop the engine. Turn off the water and remove hose. Reinstall the propeller.
