Abstract
An improvement in telescoping electric trolling motors is disclosed. The trolling motor has a telescoping shaft that changes the depth of the electric motor, and therefore the prop of the trolling motor. A cable is used to raise and lower the electric motor and telescope the shaft. The same cable is used to pivot the trolling motor into a storage position on the deck of the boat.
Claims9
A trolling motor comprising a drive unit that includes a drive head, an electric motor with prop, and a telescoping shaft with an upper, outer shaft and a lower, inner shaft, wherein the inner shaft is nested within the outer shaft, and slidingly rides on a hollow steering tube fixed to and inside the outer shaft where the telescoping shaft is interposed between the drive head and the electric motor, the inner shaft being attached to the electric motor, further including a first cable attached to one end of a rod extending through the inner shaft and also through the hollow steering tube when the telescoping shaft is fully retracted and where an opposite end of the rod attaches to the electric motor, such that pulling the first cable raises the electric motor and collapses the telescoping shaft, and such that releasing the first cable lowers the electric motor and extends the telescoping shaft, and an electric cable extending through the telescoping shaft and drive head, and adapted to carry electric current to the electric motor.
