ABSTRACT:
A propeller guard is provided with replaceable ribs that form a cage is placed around the propeller of an outboard marine propulsion unit. The ribs are suspended from a flat upper plate adapted to be bolted to a cavitation plate above the propeller. The ribs are maintained in spaced relation to each other around the propeller by the support plate and a longitudinally extending bottom bar bolted at one end to the skeg of the propulsion unit. In the event of damage to any of the ribs of the cage, the damaged rib can easily be replaced with a new one.
