      A Quick Guide to DIY Winterizing Kit

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

       Starbrite Complete DIY Boat Winerization 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 attachment for your type of engine. Check marine engine manual for specific coolant capacity and plan accordingly.

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