Trolling motor with adjustable shaft length

Abstract:

A trolling motor has a shaft with adjustable length that the user can adjust to get the optimum balance of performance and safety.

Description:

All trolling motors today have a fixed shaft length. These vary from as small as 30” to 60+”, this is done in order to accommodate boats with different heights off the water surface. In addition trolling motors also perform better when they are a certain distance below the water surface. However, having them too low puts them at greater risk of striking objects. Users can adjust the heights of these motors but they cannot adjust the overall shaft length.

The shafts on most mechanical cable steer motors built today are already two pieces. The upper part is fixed to the mounting system and the lower part sits below the mount and rotates when the user engages the foot pedal. Making it so that these two parts can be slid into or out of each other would enable a trolling motor that the user can adjust the overall length of the shaft to get the optimum balance of performance and safety.

This can be done either manually with a locking collar or electronically via a motor inside the shaft that actuates the lower part controlled via a wireless remote (key fob or foot pedal) or on screen via the MFD.

All trolling motors in the market now do not let the user adjust the length of the shaft from the trolling motor head to the propeller below. This means that users have to know the required...
