Abstract

This invention relates to a trolling motor which includes a control system capable of executing a predetermined sequence of events which will clear entangled weeds from the propeller, motor housing, and support column. The control system for the trolling motor provides momentary reversal of the propeller to accomplish reliable cleaning of the submerged components of the trolling motor without disturbing the operator selected forward speed. The system includes an input for manually activating a cleaning cycle, for periodically activating cleaning cycles, or for automatically activating a cleaning cycle upon detection of weed fouling of the submerged components.
