Boat Spring Commissioning (A Guide to De-Winterizing)

Boat spring commissioning, also called de-winterizing, is vital to safe and efficient boating. When you de-winterize your boat and prepare it for spring, you'll be ready for a smooth start to the season.

This is an excellent opportunity to catch any problems that might have developed over the winter months, so you can take care of them before your first outing. You don't want to put yourself and your passengers at risk or cause harm to your boat by getting out on the water without proper safety information, equipment, and a vessel in good shape.

All systems must be working correctly, and you want to ensure you have everything you need before the first launch of the spring season, including life jackets, fire extinguishers, signaling devices, and other items.

This guide will help you de-winterize your boat and ensure it's ready for the first warm spring day so you can stay safe and have fun on the water.

A De-Winterizing a Boat Checklist

Let's get your boat ready to launch after winterization! Use this checklist to cover every aspect of your boat's prep.

✔️Check the Boat's Exterior

The first thing to do is to scrutinize your boat's exterior. That includes inspecting the hull for damage from ice or winter storage.

Clean the outside thoroughly and remove dirt, debris, and barnacles from the vessel's bottom. Also, check the propeller and ensure it's free from damage. Sometimes, propellers can become damaged through contact with objects in the water or by fishing line entanglement.

✔️Inspect the Battery

When you de-winterize your boat, check the battery's charge and clean the terminals. If any connections or cables are worn or damaged, replace them.

Some people remove the battery from their boat for storage. If you did that, you'll want to ensure it's reinstalled correctly.

✔️Examine the Fuel System

Fuel lines can crack and eventually leak, so it's vital to check them for any problems after your boat has been out of the water for a few months. If you find an issue with a fuel line, replacing it is the right choice to be ready for spring.

Also, inspect the fuel filter and replace it if needed. If you haven't used the boat over the winter months, add a fuel stabilizer and check the fuel tank for signs of water contamination.

✔️Examine the Engine and Fluids

Check the oil and other fluid levels in your vessel's engine and change the oil if necessary. Then, inspect the coolant and ensure freezing temperatures haven't damaged the engine.

Your spring boat checklist should also include checking the belts, hoses, and other components to ensure they are free of wear and tear.

✔️Check the Electrical System

Another crucial part of boat spring commissioning is inspecting all the electrical wiring for signs of damage or corrosion. Test the power to the boat's bilge pump, lights, and all other electrical components.

If fuses have blown while the boat was stored, now's the time to replace them.

✔️Test the Bilge Pump and Other Safety Equipment

To reduce the risk of flooding, ensure the bilge pump works correctly.

Then, make sure all the navigation lights, the horn, and any fire extinguishers on board are operational. Look at the flares, life jackets, first aid kit, and any additional safety equipment, and replace anything that has expired or is damaged. 

✔️Clean and Inspect the Interior

When preparing the interior, you'll want to clean the upholstery, remove mold or mildew, and check for tears or other damage.

Also, inspect the cushions and other soft materials for water damage and ensure the storage compartments are clean and dry. This helps prevent mold buildup and should always be part of your de winterizing a boat checklist.

✔️Check the Steering and Controls

Controlling and steering your boat is crucial for safety! As you prepare your boat for a new season on the water, ensure the steering system functions smoothly and check for unexpected resistance.

Test the throttle and shift cables, as well. They should move easily and without issue.

✔️Test Your Boat on the Water

After you've checked all the systems and made any needed adjustments or repairs, take your boat for a water test. 

Launch it and check its performance on the water to ensure everything works correctly. A test run helps you catch anything that still isn't working well before loading your boat with friends or family for your first spring adventure.

✔️Schedule Professional Maintenance (If Needed)

Consult a professional marine mechanic if you're uncomfortable with specific tasks or your boat needs repairs beyond simple adjustments. You want to ensure your boat is working correctly, and you shouldn't take on repairs or maintenance you're uncomfortable with.

Proper Boat Spring Commissioning Reduces Future Problems

When you take time for boat maintenance (or boat spring decommissioning) before hitting the water when the temperatures warm up again, you reduce the chance of problems later in the season. By staying proactive with your maintenance and repairs, you can help your boat operate smoothly, last longer, and give you plenty of great days on the water.
