ABSTRACT:
A steering system (15) for a boat (16) includes a dampening apparatus (130) providing a fluid filled piston assembly (131) having a cylindrically shaped fluid containing housing (132) pivotally connected to a drive unit (18) and a piston head (137) and attached piston rod (137) pivotally connected to a vane control member (27) attached to a control vane (22). The piston head (137) provides a metering orifice (140) to control the flow of fluid between spaced fluid containing chambers (141, 142) to restrain rapid rotation of the vane (22) while within the slip stream (34) of the steerable drive (18) to control the rotative position of the steerable drive (18).
