Winterization

When lakes freeze over in Central Minnesota, un-serviced engines, fuel systems, and livewells can suffer catastrophic ice expansion damage. Our professional marine winterization service covers all critical mechanical and plumbing systems.

What Resorters Marine Winterization Includes:

  • Engine Drain & Antifreeze Flush: Full drainage of cooling passages and flushing with non-toxic marine-grade antifreeze.
  • Fuel System Stabilization: Treating the fuel tank with marine fuel stabilizer to prevent ethanol phase separation, gumming, and corrosion.
  • Engine Fogging: Coating internal cylinder walls and valves with protective fogging oil to prevent rust during dormancy (applicable 2-stroke and 4-stroke models).
  • Lower Unit Gear Lube Change: Draining old gear lube, inspecting for water intrusion/metal shavings, and refilling with fresh marine gear lubricant.
  • Livewell & Ballast System Blowout: Clearing lines and adding non-toxic antifreeze to livewells, baitwells, and bilge pumps.
  • Battery Inspection & Disconnect: Testing battery health and safely disconnecting terminal cables.

Heavy Duty Marine Shrink Wrapping


Shrink wrapping provides a custom-fit, weatherproof barrier that far surpasses standard canvas covers or tarping. We use heavy-duty, UV-inhibited marine shrink wrap to create a drum-tight shield against snow loads, ice accumulation, rain, dirt, and nesting pests.


Features of Resorters Marine Shrink Wrapping Service:

  1. Custom Support Structure: Poly strapping and support poles create a sloped superstructure that sheds heavy Minnesota snow and ice effortlessly.
  2. Integrated Ventilation System: Mold and mildew vents allow cross-airflow, eliminating internal moisture condensation under the wrap.
  3. Personnel Access Doors (Optional): Zippered access doors can be installed if you need entry to your boat during the off-season.

Frequently asked questions

Why is marine winterization necessary in Minnesota?

In Minnesota, winter temperatures routinely drop well below freezing. Any residual water left inside your boat’s engine block, lower unit, livewells, or plumbing lines will expand as it turns to ice. This ice expansion can crack engine blocks, burst water lines, destroy lower unit gearcases, and result in thousands of dollars in repairs. Winterization removes all water and replaces it with protective non-toxic antifreeze while stabilizing fuel against phase separation.
When should I winterize my boat in the Lakes Area?

You should schedule winterization before the first hard freeze in Central Minnesota, typically between late September and late October. Even a single night of sub-freezing temperatures can freeze trapped water inside an outboard or sterndrive engine. Can Resorters Marine today to schedule your winterization 320-766-8181.  We are located in Osakis, MN near Alexandria, Miltona, Carlos, and Glenwood lakes area.
Can I winterize a 4-stroke outboard engine myself?

While basic fuel stabilization is simple, professional winterization requires draining lower unit gear lube to check for seal leaks (water in gear lube appears milky and will crack the gearcase when frozen), flushing cooling passages, fogging internal components, and purging livewell pumps. Professional service guarantees your engine warranty remains protected and avoids missed freeze pockets. Give us a call and let the professionals handle your winterization 320-766-8181 located near Alexandria, MN
Why is shrink wrapping better than using a standard boat cover?


Standard canvas or snap covers are not designed to withstand heavy Minnesota snow loads or ice accumulation. Water pools on canvas covers, causing them to sag, tear, or leak. Shrink wrap is heated to form a drum-tight, custom-contoured seal over a supported frame. Snow and ice slide right off, and the sealed fit prevents wind, rain, dirt, and animals from entering the boat. Shrink wrapping is ideal if you plan on storing your boat outside.
Will shrink wrapping cause mold or mildew inside my boat?


No, provided it is installed with proper ventilation. At Resorters Marine and Outdoors, we install specialized air vents into the shrink wrap to promote continuous airflow. This ventilation allows interior air to circulate and moisture to escape, preventing dampness, mold, and mildew growth.
How do you prepare a boat before shrink wrapping?

Before bringing your boat in for shrink wrapping, ensure all personal items, life jackets, towels, fish finders, and food/beverage items are removed. The interior carpet and seating should be completely dry to prevent trapping moisture under the wrap. Make sure to call 320-766-8181 and schedule an appointment to shrink wrap your boat near Miltona, MN.
What types of watercraft can be stored at Resorters Marine and Outdoors?

We accommodate pontoons, tritoons, aluminum fishing boats, fiberglass runabouts, ski boats, and personal watercraft (PWCs).  You can also winterize your boat through Resorters Marine for a storage discount.
