Keeping your boat shipshape!
Winterization Checklist
Work through these before the first hard frost to protect your boat over the off-season.
Before you start
Winterizing is the difference between a spring that starts on the first turn and a spring full of repairs. Do it before the first hard frost.
Plan it with the Winterization Planner for your region's timing.
The checklist
- Stabilize the fuel. Add fuel stabilizer and run the engine long enough to work it through the system.
- Fog the engine. Fogging oil protects cylinders from corrosion while it sits.
- Drain water systems. Engine block, livewells, ballast, and fresh water — standing water freezes and cracks.
- Change lower-unit oil. Old oil can hold water; fresh oil protects the gears all winter.
- Remove the battery. Store it inside on a maintainer. A battery left to discharge all winter is often dead by spring.
- Protect the outside. Cover, shrink-wrap, or indoor storage — sun and snow both damage gelcoat and vinyl.
