Boat Winterization Supplies 

PowerBoatSupply.com offers a wide selection of top-quality boat winterization supplies, including anti freeze, cleaners and solvents for winterization, tarps, and many other products to protect your watercraft from the cold temps and harsh winter elements.   

Our inventory contains essential boat winterization tools and equipment from trusted industry names. If you have any questions about which products are right for your needs, we’ll use our extensive knowledge to point you in the right direction.  

What Are the Steps to Winterize a Boat? 

At PowerBoatSupply.com, you can get all the supplies needed to winterize a boat in one convenient place, including complete winterization kits to ensure everything you need is right at your fingertips. Once you’ve gathered the necessary items, you’ll need to perform the following steps: 

  • Replace oil and oil filters 
  • Apply fogging oil to engine intake 
  • Pour in fuel additives for winterization 
  • Drain water from pumps  
  • Add antifreeze 
  • Check components, such as hoses and lines, for defects 
  • Thoroughly clean the exterior and the interior of the boat 
  • Drain and rinse the waste holding tank 
  • Apply boat covers and tarps for winter preparation 

The specific winterization steps can depend on the type of vessel you own and where you’ll be storing it (i.e., interior vs. exterior storage). As a result, you may need to amend the process to best suit your needs.  

At What Temperature Should I Winterize My Boat? 

Boat winterization is a must if temperatures in your area are expected to drop to freezing or below during winter.  

The best time to winterize your boat is before winter starts, when temperatures are still moderate. If possible, winterize your boat indoors or when outdoor temps are mild. Getting a jump on winterization during the fall is ideal.  

How Long Does It Take to Winterize a Boat? 

The size of your boat will typically determine how long the winterization process takes. Consider that larger boats with more complicated engines and other systems can take as long as three days to fully winterize.  

With small and medium-sized boats with less complex components, timelines are much shorter. A small vessel may take just two hours to winterize, while a medium-sized watercraft can take about six hours. Regardless of the size of the boat, you should perform winterization slowly and carefully for the best results.  

Winterizing a Boat With Help From PowerBoatSupply.com 

Decreasing temperatures, snow, sleet, rain, and wind can negatively impact the condition of boats. That’s why proper storage during the cold months is crucial, and reliable storage requires the right boat winterization supplies from PowerBoatSupply.com.
