Step-by-step guide to protecting your engine during the off-season. Don't let freezing temps crack your block.
Winterizing your outboard is crucial to extending its life and ensuring it starts up on the first crank next spring. Here is a comprehensive guide to getting your 4-stroke ready for the cold.
1. Flush the Engine
Run the engine with fresh water using muffs or a flush port for at least 15 minutes to remove salt and sediment.
2. Stabilize the Fuel
Add a high-quality fuel stabilizer to your tank and run the engine for 10 minutes to ensure treated fuel reaches the injectors.
3. Change the Oil
Old oil can become acidic and damage internal components. Change the engine oil and filter before storage.
4. Fog the Cylinders
Remove spark plugs and spray fogging oil into each cylinder to prevent corrosion on the cylinder walls.
