Boat Winterization

Boat Winterization: Supplies for Long Term Boat Winter Storage

Wholesale Marine offers a full range of boat winterization tools and winterizing products designed to protect your vessel after the boating season ends. These include:

Marine Antifreeze

• Marine antifreeze products made with USP-grade ingredients, including propylene glycol. These additives not only prevent freezing but also help prevent rust and corrosion. Whereas auto antifreeze is made to be both a cooling agent and lowers the freezing point but can cause freeze damage to marine engine components.
• Starbrite marine engine antifreeze in -50, -100, and -200 options. This Non-Toxic Antifreeze provides excellent cold weather and corrosion protection for freshwater systems and all engines. Its premium additive package prevents corrosion of aluminum, copper, brass, and solder, but will not harm rubber, seals, or hose materials.

Marine Heaters & Dehumidifiers

• Marine heaters and boat dehumidifiers that are mold and mildew resistant from brands you’ll recognize like Caframo and Davis Instruments. Moisture can be a real enemy to boats, so keeping compartments free of moisture will help prevent mold and mildew conditions.
• Starbrite’s No Damp buckets that can be used on land or at sea. Place the bucket in any damp area and the pellets will absorb the moisture in the air. This product is an excellent way to prevent high humidity on your boat when storing for extended periods.
• Marine heaters as an ideal solution to creating comfortable climates out on the water. There is nothing better than enjoying a morning onboard your boat, though those mornings can be a bit chilly.
• The True North’s Cabin Marine Air Heater, a compact, durable marine boat heater. With five air heating settings you can find the right temperature for maximum comfort. The anti-freeze setting is a great boat winter storage solution that automatically turns on when the weather drops to 38°F, ensuring the air temperature in the room remains above freezing point.

Boat Mildew & Mold Prevention

• A full line of boat care products, including boat mold prevention and boat mildew products. Whether you are looking to remove or prevent mold and mildew, Wholesale Marine has what you need to prevent mildew stains, clean up when they occur, and even products to prevent the unpleasant smell they produce.
• Starbrite Mildew Stain Remover, designed for fiberglass, vinyl, plastic, and painted surfaces, quickly removes mildew and begins working on contact. The buffered formula will not weaken fabric or harm vinyl upholstery. This boat mildew removal product is a great alternative to bleach.

Boat Shrink Wrapping

• Marine shrink wrapping your boat, which can help protect your investment during the winter months or during dry docking of your vessel. When done properly, it provides a tight barrier from the harsh outdoor elements such as UV rays, freezing temperatures, and moisture that can cause permanent damage to your boat.
• Shrink wrapping your boat is a relatively easy task when armed with the right tools. Whether you're a DIYer and doing this task by yourself or having the job performed by an experienced marine technician, Wholesale Marine has all the boat shrink wrap products you need.
• Boat winterizing kits that allow you to quickly and efficiently prepare your inboard and outboard engines for winter storage. Unless you live in the sunniest parts of the country where you can boat year-round, right after school starts, it’s time to think about preparing your boat for the winter months ahead.

How to Winterize a Boat: Made Easy with Wholesale Marine

To start the process, it is important to change the oil to protect your engine from rust and corrosion. The Jabsco Little Pal Marine Oil Change Pump is a multipurpose hand pump that can be used to drain engine oil from your engine. We also carry a full line of marine engine oil and oil filters. It is also a good idea to drain and replace gear oil.

Fuel systems also need to be protected, and adding a fuel stabilizer to the fuel tank can help prevent the fuel from breaking down and allow contaminants to take over and cause poor engine performance. Add Sta-Bil Diesel Fuel Stabilizer and run the engine for a few minutes to treat the entire system.

Use a Complete Boat Winterization Kit

If it is your first time, we recommend Starbrite’s Do-It-Yourself Winterization Kit. The kit includes everything you’ll need to winterize and descale your outboard, with illustrations and step-by-step instructions. Starbrite did not forget stern drive owners, and offers their 100 Complete Sterndrive Winterization Kit.

Starbrite's Marine Winterizing Kit comes with a 5 gallon tank, gate valve/cap and clear hose. You will need ear muffs or flushing attachments for your type of engine. Check marine engine owners manual for specific coolant capacity and plan accordingly.

1. Fill a 5 gallon tank with the appropriate amount of desired Starbrite's Antifreeze making sure the vent cap is open.
2. Once the tank is filled with antifreeze, tighten the gate valve/cap and lay tank on side with gate valve facing down.
3. Place marine engine flushing attachment over engine intakes.
4. Attach a clear hose to the gate valve at one end and flush the attachment at the other end.
5. Open gate valve to start flow of antifreeze into clear hose.
6. Start the engine and let it run at idle speed until antifreeze comes out of the exhaust/water outlet of your engine.
7. Immediately shut off the engine, close the gate valve on the tank and remove the marine winterizing Kit.
8. When the engine is ready to be put back into use, flush the cooling system with fresh water to remove antifreeze.
9. Dispose of antifreeze in compliance with local, state and federal laws.

Protect your internal engine parts by flushing and draining residual water and coolants. Water expands when it freezes, possibly causing engine damage. Boat Winterization kits like the Starbrite Winterization Kit make winterizing your engine a breeze. These kits come stocked with antifreeze, fogging oil, and fuel treatment to protect your outboard engine during winter storage.
