I helped my friend replace his on a Marine Trader. The hole was badly worn so after driving a piece of dowel into the old hole, I redrilled with a holesaw to accept a piece of cutlass bearing which was epoxied in b/4 putting everything back. There should be 1/2" a hole through the bottom of the skeg to let sand out thats how the old hole got so worn, the stock just sat in sand and wore the hole larger. My friend reported quieter operation with the cutlass lined hole.
