  • Patent number: 3999500
    Abstract: A pivotal mount for a trolling motor includes a deck bracket having a housing arm pivotally mounted at one end. A gear mechanism within the arm has a fixed bevel gear on the pivot arm axis meshing with a bevel gear on a rotatable torque tube. A drive bevel gear is secured to the opposite end and meshes with a gear sector on a coupling head pivotally mounted in the outer end of the arm. The head includes a swivel support element within which the trolling motor unit is rotatably mounted. The coupling head and motor unit are located between a depending propulsion position and transport position in response to the 180.degree. swinging of the pivot arm. The torque tube is coupled to the bevel gears by sliding couplings and is coupled to a locking unit for the arm and a separate locking unit for the gear sector to lock them in the propulsion position and simultaneously release them raising to the transport position.
