- Shut off generator and water supply. Shut off fuel valves.
- Replace motor oil and filter. Replace spark plugs. Add 30W oil to generator and check oil level.

See owner’s manual for your particular outboard for proper winterization. Or take boat to authorized outboard dealer.
Pro Tip: If you are storing your boat outside in very cold weather, a easy trick you can do, remove your pilot deck plate (where you stand when driving the boat) and place a 75 watt trouble light inside compartment, place deck plate back on. This will keep the water pumps and the interior of your console warm during the long winter months.
