  • Patent number: 5018997
    Abstract: A skeg protector is mounted on the leading edge of the skeg of a boat motor. The protector is in the form of a channel of stainless steel fitted on the skeg with the base of the channel spaced forwardly of the leading edge of the skeg. A rubber strip extends along the inside of the channel. To mount the protector on the skeg, elongate, horizontal slots are formed in the channel flanges and holes are drilled through the skeg in line with the slots. Dome head machine screws and nuts are fastened through the slots and the bores of the skeg. These slots allow the skeg protector to yield somewhat on impact with a submerged object.
