ABSTRACT:
A dampening assembly used in watercraft to isolate the motor from the deck of the watercraft. In an embodiment of the invention, a frame including cross-members and a plurality of brackets supports the deck. The dampening assembly of the present invention extends from the brackets of the frame to the motor and retains the motor at a position ensuring the motor does not contact the frame. The only path available to the vibrations generated by the motor is represented by the dampening assemblies that direct the vibrations to the brackets and tubes, thereby eliminating the high amplitude, low frequency vibrations that readily transfer throughout the deck and frame structure. In this manner, the vibrations are prevented from traveling directly through the cross-members of the frame and into the deck of the watercraft.
