  • Trim mechanism with automatic return
    Patent number: 4331430
    Abstract: A tilt mechanism (10) for a marine propulsion device has a swivel bracket (13) pivotally attached to a transom bracket (11). A trim pin (21) is carried by a trim pin carrier (27) which is pivotally attached to the swivel bracket (13). The trim pin (21) travels in cam tracks (20) on the transom bracket (11) and engages notches (22, 23, 24) in the cam tracks (20) to establish trim and tilt positions for the propulsion device. An axial step (36) in the cam track (20) shifts the trim pin (21) to a return cam surface (25) to allow automatic return from the uppermost to the lowest position.
