  • Nicked Propeller Repair

    My friend and customer ran his boat in shallow water and the propeller hit the ground, which nicked the edge of the propeller. I have seen more damage when a propeller hit a branch in the water. The following four pictures show the damage to the propeller.

    The first step was to sand off the paint so that it wouldn’t contaminate the weld. I also sanded off the mushroomed Aluminum near the nick.

    I used a bar clamp to rigidly clamp the propeller to my welding table so that it wouldn’t move while I was working on it.

    I used a piece of copper to keep the weld from sagging.

          My friend said that he would get it balanced.

            Nice fix. I have been doing them since the late 70’s. Zero issues with balance.
