ABSTRACT:
A guard attachable to the lower unit of an outboard motor preventing direct impact between submerged hazards and the elements of the lower unit. The guard includes two angle brackets, a rigid bar attached to the angle brackets at a top end, and a skeg pocket and fin attached to a lower portion of the bar. The guard descends from a position forward of, and substantially level with, the cavitation plate to a point below the skeg. The guard prevents damage to the entire lower unit, including the propeller, upon impact with a submerged obstacle.
