Did you know that de-winterizing your boat can save you money and protect your passengers from harm? It's the preparation stage before the fun

Boat owners follow the seasons like clockwork. The boat comes out in the spring, has play time in the summer, and inevitably goes into hibernation during the cold winter months. Maintaining your boat is a constant process, but it's that last section of the cycle that needs the most attention. It takes a lot of work to winterize and then de-winterize your boat. It's tedious, but it's essential to your machine's longevity.

Before we delve into our quick tips, it's worth mentioning that every boat—every make and model—has different procedures for testing its equipment. Your best strategy is to use these steps as a guide and then consult your owner's manual for in-depth instructions.

De-winterizing your boat in seven easy steps: let the springtime fun begin!

A quick note: we're assuming that you've done all of the necessary work to winterize your boat before storing it. Without those steps completed, the advice we give here may not work for you. In other words, make sure you're not putting the cart before the horse—winterizing and de-winterizing your boat are connected processes. 

Step 1: Check the battery 

The typical battery life for a boat is 4-5 years. Re-fill the battery with fresh distilled water and check the charge. If the battery still holds a strong charge (under a battery tester), then you're in good shape.

Next, remove the wires from the charge posts and scrub each post clean of dirt and rust. A small wire brush should do the trick. Finally, coat the posts in lithium grease to protect them from further erosion.

Step 2: Test the electronics 

Test all the switches, knobs, and electrical equipment on the boat. Flip the switches on the helm and cabin, being sure not to skip even the most insignificant one (all electrical systems are connected). Now that the battery is running, switch it off and see if the automatic bilge pump float switch works. 

Step 3: Change the engine oil

Properly checking the engine is paramount to de-winterizing your boat. Make sure the oil levels are correct first. If you didn't change the oil before storing the boat for the winter, now would be the time to do it. Don't forget about the outdrive oil, too. Fill or change those as needed.

Here are more things to check your engine for when de-winterizing your boat:

  • Power steering fluid levels 
  • Coolant levels 
  • Leaks below the engine area 
  • Visible cracks or wear in fuel lines

Step 4: Fill the cooling system 

If you flushed out the cooling system before storing the boat, now you can fill it back up with equal parts water and antifreeze. If you left the water/antifreeze mixture over the winter, drain it out, and then fill it. Check the hoses for any cracks or wear, and search around for any visible leakage. 

Step 5: Inspect the gas tank and fuel lines 

Your gas tank and fuel lines are in danger of developing rust during the winter. Hopefully, you filled up the tank before storing it, and no moisture had a chance to settle. However, that doesn't leave out the fuel lines. These lines have a tendency to crack during cold temperatures, so inspect them and replace them as necessary. 

Step 6: Make sure your safety gear is in order 

This step is vital (potentially life-saving, as a matter of fact). Make sure that your safety equipment is prepared, not expired, and not visibly damaged. 

  • Check for the proper amount of flotation devices.
  • Read expiration dates for fire extinguishers. 
  • Test all the lights in the cabin and on deck.
  • In case you need it, organize your paperwork. 
  • Check the signaling equipment, such as horns, flares, and whistles.

Step 7: Check the belts for wear 

The belts connecting the engines and motors can quickly wear during the off-season. You can check these manually with your hands for tears in the fibers. Push down on the belt slightly to see if there is too much slack as well. If you notice any black soot around the machinery, it may be time to switch out your belts for new ones. 

De-winterizing your boat is an essential part of its life cycle—don't overlook it!

Maintaining your boat is a full-time gig. Putting it away for the winter, getting it back on the water, and keeping it in good shape throughout the summer takes a lot of work. If you don't follow through with each step, you could miss something that costs a lot of money to repair in the future. Also, when the winter comes around again, be sure to keep your boat safe from flooding damage and store it away from hazardous areas. 

But why go through all the work to keep your boat in good condition if you're not even covered for an accident? We can supply you with excellent coverage at competitive rates. Check out our insurance packages here.
