Abstract

Disclosed herein is a shock arm adapted to be mounted between a trailer and the shaft of an outboard motor attached to a boat carried by the trailer. The shock arm includes a lower member rigidly affixed to the trailer frame and an upper member having a V-shaped and adapted to receive the motor shaft. Between the lower and upper ends is a shock absorber which absorbs the shock of the motor whenever the trailer hits a bump in the road. A hydroelectric tilt mechanism, may be provided as a part of the motor to return the compressed shock absorber to the normal position or a spring may be included with the shock absorber to cause it to return to the normal position.
