Camco DIY Boat Winterizer
Reliable shipping
Flexible returns
Prepare your boat for winter storage without leaving the trailer with the Camco DIY Boat Winterizer. This gravity-fed system lets you flush, protect, and prep your engine for off-season storage directly from the trailer, using just five gallons of antifreeze and your preferred flusher—no tools or extra equipment required.
Designed for both inboard and outboard engines, this reusable, budget-friendly winterization solution helps prevent freeze damage and corrosion. It’s a one-person setup that saves time, avoids costly service calls, and keeps you in control of seasonal maintenance.
How it works
Attach the kit to your boat’s flushing system, add five gallons of antifreeze, and connect your flusher. The gravity-fed design pushes antifreeze through the engine cooling system, flushing out water and injecting antifreeze to protect critical passages during storage. When you’re done, simply shut off the valve and store—the kit is ready for next season.
