ABSTRACT:
Mud bug, a portable system for propulsion of small boats consisting basically of a carrying frame (10) housing controls for forward and reverse speed, steering, and tilt of a remote mounted outdrive assembly. Control is accomplished through flexible sheathed cables. Adjustable tension provided by (66) and (74) allows the outdrive to tilt when in forward operation if underwater obstruction is encountered, and also provides lift and lock to tilt the outdrive up and free of the water. When operating in reverse, (62) will automatically lock the outdrive down. The carrying frame provides a boom (19) and attachment for mounting the outdrive on boats with unavailable motor mounting. The carrying frame also provides outriggers (14) for stability and a lower rear seat mount. Local adjustment of both the outdrive height and tilt are controlled by the single fastener (54) in the adjustment clamp (53) on the outdrive mount.
