Boat Winterization in Colorado:Get Your Boat Ready for Winter Storage

As the crisp autumn air settles over Colorado, it's a clear sign that the boating season is coming to an end. Neglecting to properly prepare your boat for the harsh, freezing temperatures of a Colorado winter is the single biggest mistake a boat owner can make. The ice expansion inside an engine block, plumbing, or any other water-filled system can cause catastrophic and incredibly expensive damage. A simple, proactive service can save you from a ruined season and a massive repair bill come spring.

At Island Lake Marine, our Fort Collins, CO, service center is your trusted partner for professional boat winterization. We are experts in safeguarding all types of vessels, from high-performance wakesurf boats to spacious pontoons and versatile runabouts. Our meticulous winterization process is designed to protect every system on your boat from the damaging effects of cold weather, giving you complete peace of mind all winter long.

The Island Lake Marine Winterization Experience

We've designed a service process that is as thorough as it is convenient. Our Fort Collins, CO, location is a central hub for boaters across Northern Colorado and the surrounding areas, who rely on us for expert care.

  • Expertise for All Boats: Whether you have a wakesurf boat with a complex ballast system, a pontoon with a simple outboard, or a cruiser with multiple freshwater systems, we have the knowledge and experience to service it correctly. Our certified marine technicians are trained to follow manufacturer-specific procedures for all major engine and boat brands.
  • More Than Just a Flush: We go far beyond simply flushing out antifreeze. Our comprehensive winterization service is a multi-point process that addresses every system on your boat. We will uncover any potential issues that need to be addressed before they become a bigger problem, such as worn belts, leaking hoses, or signs of rodent intrusion.
  • Transparent & Thorough: We believe in clear communication. You'll receive a detailed, easy-to-understand checklist of all the services performed. We will explain every step of our process and answer any questions you may have. Our goal is to make storing your boat simple and worry-free.

Our Comprehensive Boat Winterization Service Includes:

  • Engine & Propulsion System Prep: We drain all water from the engine block and cooling systems, fill the engine with a non-toxic marine-grade antifreeze, and use fogging oil to protect the internal components from corrosion. We also perform a routine oil and filter change to remove corrosive acids that have built up over the season.
  • Fuel System Stabilization: We fill your fuel tank to prevent condensation and add a marine-grade fuel stabilizer. We then run the engine to ensure the stabilized fuel circulates throughout the entire system, protecting your fuel injectors and carburetor from gum and varnish buildup.
  • Plumbing & Freshwater Systems: We meticulously drain all freshwater systems, including sinks, showers, and livewells. We then pump non-toxic antifreeze through the system to prevent freezing and cracking in the lines and pumps.
  • Electrical & Battery Care: We disconnect the battery, clean the terminals, and recommend storing it in a cool, dry place on a battery maintainer to ensure it holds a full charge.
  • Outdrive & Lower Unit Service: We drain the old gear lube and inspect it for signs of water intrusion. We then refill with fresh, high-quality gear lube. This is a crucial step to prevent water from freezing and destroying the gears and bearings inside your outdrive.
  • Custom Shrink Wrap: As a final layer of protection, we offer professional shrink wrap services. A custom, heat-sealed shrink wrap cover is far superior to a standard tarp, as it sheds snow and water, prevents pooling, and protects your boat from pests and debris all winter long.
