As the season winds down on the lakes around Kansas City, every boat owner faces a critical task: protecting their vessel from the harsh Midwest winter. Proper winterization and secure winter storage for boats isn’t just about avoiding a chore—it’s about safeguarding your investment against freezing temperatures, corrosion, and pest damage.
At Midwest Marine in Grandview, MO, we are your full-service resource for both expert winterization and secure storing a boat until spring.
Here is your essential checklist and an overview of your storage options for the off-season.
The Essential Winterization Checklist: How to Store Boat for Winter Safely
Missouri winters demand a meticulous approach to keep your boat’s vital systems intact. Whether you own a Bennington pontoon, a SeaArk fishing boat, or a Crownline bowrider, follow these key steps:
1. Engine and Fuel Protection (The Freeze Barrier)
-
Stabilize the Fuel: Top off your fuel tank and add a marine fuel stabilizer. Run the engine for 10-15 minutes to ensure the treated fuel circulates throughout the entire system.
-
Change the Oil: Old, contaminated oil contains acids that will corrode internal engine components during storage. Always perform an oil and filter change when the engine is warm.
-
The Critical Antifreeze Flush: For inboard and I/O engines, water must be drained from the cooling system and replaced with non-toxic marine antifreeze. This is the single most important step to prevent a cracked engine block from freezing.
-
Fogging: Spray storage “fogging” oil into the engine’s cylinders to create a protective, anti-corrosion barrier on all internal moving parts.
2. Draining and Interior Prep
-
Drain All Water Systems: Completely empty every system that holds water, including the freshwater tank, head, livewells, and washdowns. Flush these systems with non-toxic antifreeze.
-
Battery Maintenance: Remove the battery, clean the terminals, and store it in a cool, dry place. Keep it connected to a marine trickle charger throughout the winter.
-
Pest and Mold Control: Thoroughly clean the interior. Remove all food, trash, life jackets, and fabrics—anything that can attract mice or encourage mold. Leave cabinets and storage compartments slightly ajar for ventilation.
Your Options for Winter Storage for Boats
Once your vessel is professionally winterized, you need a safe place for storing a boat for several months. For boaters in the Grandview, MO, and Kansas City area, you have options:
Option 1: Professional Storage at Midwest Marine
We offer specialized winter storage for boats right here at our Grandview facility. When you store with us, you get:
-
Secure Environment: Your boat is protected from theft, vandalism, and harsh weather.
-
Convenience: We handle the haul-out, winterization, and storage all in one seamless process.

Option 2: Home Storage on a Trailer (DIY)
If you have a secure, covered garage or shed, this is a viable option. However, ensure:
-
You invest in a high-quality, custom-fit, breathable cover. A cheap tarp can trap moisture and cause mold.
-
The boat is parked on a solid surface with the bow slightly raised to promote drainage.
-
You implement pest deterrents aggressively, as mice often seek shelter in boat interiors during the winter.
