Abstract

See full text

An assembly is provided for mounting a sonar depth sounder transducer on an electric trolling motor such that the transducer is protected from entaglement with vegetation and from being knocked out of a predetermined orientation relative to the boat. The conventional bearing cap connected to the nose of a trolling motor is replaced by a bearing cap having a sonar tranducer integrally mounted therein such that the power cable, extending from the depth sounder in the boat to the transducer, is routed through the inside of the trolling motor housing and through the hollow tubular trolling motor support shaft. A power cable guide is mounted inside the trolling motor housing and is supported by a guide ring for positioning the power cable along a path preventing engagement with the armature, rotor and other moving parts in the trolling motor.
