ABSTRACT:
A motor mount for attaching a motor, such as a trolling motor, to a boat includes a bracket, a pair of pivotable support arms and a motor support. The bracket may be removably attached to the transom or to the bow of a boat. The bracket, the support arms and the motor support form a 4-bar linkage that permits the motor to be moved between a fully deployed or lowered position and a fully stowed or raised position. As the motor is moved between the deployed and stowed positions, it moves through a first, generally vertical translation phase of motion during which it maintains a generally vertical orientation, and a second, generally pivotal phase, in which it is rotated from the generally vertical orientation to a generally horizontal orientation. An intermediate stowed position is provided just beyond a transition point between the two phases of motion. The mount facilitates temporary removal of the motor from the water, such as for displacement of the boat between fishing spots, without requiring adjustment of the motor depth and without subjecting the motor mounting tube to excessive bending moments due to cantilevered extension of the motor.
