ABSTRACT:
A marine mammal guard for an outboard motor having a drive shaft housing, an anti-cavitation plate, a lower support unit, a gear casing, a skeg and a propeller hub with a plurality of propeller blades radially thereabout. The guard comprises a protective housing having a pair of forward intake ports and a rearward exit port. A mechanism is provided for securing the protective housing to the lower support unit. The protective housing will extend about the gear casing, the propeller hub and propeller blades below and parallel to the anti-cavitation plate and above the skeg, so as to prevent animals and other objects also submerged within water from coming into contact with the propeller blades of the outboard motor.
