As the boating season comes to a close, preparing your boat for winter storage is one of the most critical steps to protect your investment. Winterizing not only shields your boat from the harsh Midwest elements but also saves you time, money, and frustration when spring rolls around.

At Perdue Marine, we’ve winterized thousands of boats over the years—each one getting a detailed inspection and tailored service plan. Whether you’re a seasoned boat owner or a first-timer, here’s what you need to know to winterize your boat the right way.

Start with a Full Inspection

A proper winterization begins with a thorough inspection. Our certified technicians look for any cracks, weak joints, or damage to the hull and propeller. We also check the console, lights, cables, battery, and fluid levels to make sure everything is in good shape for storage.

Drain and Protect the Engine

Freezing temperatures can wreak havoc on your boat’s engine if not properly drained and treated. We remove water from the block and gear case, add antifreeze to protect from freezing, and replace lower unit lubricants. A fresh oil and filter change—preferably with synthetic oil—will keep everything running smoothly when you’re ready to hit the water again.

Stabilize the Fuel and Disconnect the Battery

We use a proprietary fuel stabilizer cocktail that prevents condensation and breakdown while your boat is in storage. The battery is disconnected, cleaned, and maintained throughout the offseason to ensure maximum longevity.

Clean and Cover

A clean boat lasts longer. From hot water pressure washing the carpet and seats to buffing the exterior and removing algae, our detailing services ensure your boat stays in peak condition. Finally, we cover it securely—either indoors or out—to protect it from dust, pests, and weather.

Trust the Experts

Winterization isn’t a one-size-fits-all process. That’s why Perdue Marine customizes each service to the boat’s manufacturer guidelines. You’ll even receive a full checklist of completed services and any repair recommendations before spring startup.
