Abstract

A sensing cage (22) is located around the propeller of a pendently mountable propulsion unit (9), eg an out­ board motor, and arranged so that a blow delivered to the cage from below or in any lateral direction frees a detent means (15) to release energy stored in springs (11) disposed so as to raise the propulsion unit with respect to a support frame (1). The springs are re­ energised when the propulsion unit is pushed down again by manual pressure. No replacement of parts is needed before redeploying the unit.
