We winterize all makes and models of outboards and inboards Winterizing is more than just sloshing in some fuel stabilizer, draining the engine and adding antifreeze. Consider it to be a very important process to protect your investment that runs from bow to transom, above and below deck. Because boats and engines all differ its important to have a professional handle it,  Winterization procedures protect boat systems and gear from freeze damage. Winterizing also guards items such as batteries, inboard/outboard engines, lower units and stern drives from damage and wear that lying idle during the brutal winter months can cause. Winter's biggest dangers to engines are freezing, corrosion and fuel degradation. Here is our check list for winterizing our customers boats.

  • 7mil industrial shrink wrap (used for most boat storage applications)

  • Optional 10mil industrial shrink wrap for long haul transportation of your boat at higher speeds

  • Vents to create air circulation, which reduces moisture buildup and helps prevent mold and mildew from forming.

  • Moisture Control Desiccant Bags - used in enclosed spaces to keep condensation from forming.  Our Desiccant Bags are rated for three (3) cubic feet and have been tested to absorb moisture for as long as six months.

  • Framing & Strapping - essential for creating structure when shrink wrapping medium to large boats.  Center wood framing post is installed and strapped as the main structure.  1/2" Strap is used to create the sideways "Ribs".  1/2" Strap is also used to create "Drop Loops". 1/2" Strap is used once more to create the "Perimeter Strap.

  • Optional Zipper Access Door - provide quick entry into a shrink wrap enclosure. Useful for inspection hatches, full or limited access doors are a great solution for lifting points, tie-down rings or any other quick access through a shrink wrap installation.
