How to Winterize a Pontoon Boat

Winterizing a pontoon boat is essential for protecting it against the harsh winter weather. The process of winterizing a pontoon boat ensures that the boat is in good condition and ready for use when the warm weather returns. This article will provide a step-by-step guide to winterizing a pontoon boat and make sure it is prepared for the cold months ahead.

How to Winterize a Pontoon Boat

To winterize a pontoon boat, begin by draining all the water from the engine, bilge, and live wells. Once the water is drained, add a winterizing solution to the fuel tank and run the engine for a few minutes to circulate the solution throughout the engine. If the boat has an onboard water system, drain all the water from the tanks and lines. Lubricate all the exposed metal parts and fittings, cover the boat, and remove the battery to store it in a warm, dry place for the winter months.

  1. Drain the engine oil and replace it with non-detergent oil.
  2. Remove the outboard motor and store it in a safe, dry place.
  3. Add fuel stabilizer to the gas tank and run the engine until the stabilizer has circulated through the fuel system.
  4. Remove the spark plugs and squirt a few drops of oil into each spark plug hole.
  5. Disconnect and remove the battery and store it in a dry place.
  6. Remove the drain plug from the bottom of the pontoon boat and allow the water to drain completely.
  7. Inspect and clean the interior of the pontoon boat and store any supplies that may have been left onboard.
  8. Remove the pontoon boat cover and dry the interior.
  9. If the pontoon boat has an outboard motor, spray the exposed surfaces with a lubricant.
  10. Cover the pontoon boat with a tarp and secure the tarp with rope.

To further protect the boat during the winter, it is recommended to remove any electronics from the boat and store them in a dry location. It is also beneficial to flush the motor with an engine flush solution, and then fog the cylinders with oil to prevent corrosion. Inspect the pontoon for any holes or cracks and repair them before covering the boat for the winter. Check our article when to winterize to get most of it.
