Abstract
A resilient "C" shaped propeller guard, pivotally attached to the propeller housing below the propeller and linked to a movable semi-rigid cable at its other end, transmits impact forces upon the guard through the cable thereby shifting the output of an outboard motor to the neutral position when the guard encounters propeller damaging objects.
Claims2
A guard for outboard motors having propellers, propeller housings and a trailing skeg conprising:
- a. "C" shaped resilient propeller guard bar having a first and a second end;
- b. means for pivotally attaching said second end of the guard bar to the propeller housing at a point below said propeller;
- c. an upwardly extending semi-rigid cable slidably contained within a semi-rigid sheath affixed to said skeg, one end of said cable in communication with the transmission control for said outboard motor;
- d. means for connecting the second end of said semi-rigid cable to the first end of said guard bar such that pivotal movement of the guard bar induces translational movement of said cable within said sheath providing control of said motor transmission thereby.
