How to Remove Water From a Boston Whaler Hull

Your Boston Whaler's hull is made of closed-cell foam that is bonded to an outer protective layer of fiberglass. When water gets into your Whaler's hull, it means that there is damage to the fiberglass layer, or one of the drains is improperly sealed. When you get water in the hull of your Boston Whaler, use the method recommended by the manufacturer to drain the hull. Make sure it is completely dry before you inject resin into the empty void created by the water to fix the damage.

Instructions

    • 1

      Tap around the hull with a tap hammer or maul until the tapping sounds muted or dull. This is where the water is trapped in the hull. Continue tapping around that area until you have identified the full area of the hull with trapped water.

    • 2

      Draw around the perimeter of the area that you have identified with the tap hammer.

    • 3

      Drill one-eighth-inch holes at the bottom of the void where the hull holds the water. If the void is only a small area, such as the size of your fist, use only one hole. Use more for larger water pockets. The water will drain and evaporate through the holes.
