Abstract
Two embodiments of concentric tilt and trim cylinder arrangements for machine propulsion units for achieving trim and tilt-up operation. Each embodiment includes an arrangement that permits the outboard drive to pop up when an underwater obstacle is struck, but which preclude popping up operation when operating in reverse. In addition, one embodiment incorporates an arrangement for ensuring against inadvertent trim up when trim down is being called for.
