- Thoroughly clean the boat inside and out to remove dirt, debris, and any moisture that could lead to mold or mildew. Once clean, cover the boat with a high-quality, breathable cover to protect it from the elements and to keep pests out.
- Choose an appropriate storage location for your boat. Indoor storage is ideal, but if that’s not possible, find a level spot outdoors where the boat can be stored upside down or covered to prevent water and snow accumulation. If storing outside, make sure to use a cover that can withstand the weight of snow and the rigors of winter weather.
Preparing the Fuel System
To winterize your bass boat’s fuel system, start by draining all of the fuel from the tank. This is a crucial step in preparing your boat for the winter season.
Begin by locating the fuel tank drain plug, usually found near the bottom of the tank. Use a wrench to loosen the plug and let the fuel flow out into a suitable container. Make sure to dispose of the fuel properly, following local regulations.
Once the tank is empty, remove the fuel filter and inspect it for any signs of damage or clogging. If necessary, replace the filter to ensure optimal performance when you launch your boat again in the spring.
