ABSTRACT:
A boat steering assembly having a tiller lever for providing a steering input upon being pivoted about a first pivot axis and an actuating lever supported for pivotal movement about a second pivot axis. The ends of the levers are interconnected in order to pivot the tiller lever upon pivoting movement of the actuating lever and for positioning the levers in parallel relationship with one another in a neutral position. The length of the tiller lever from its first pivot is longer than the length of the actuating lever from its second pivot to their respective ends. There is also an acutator assembly comprising a reciprocating member having a hydraulically operated piston at each end which is slidably disposed for movement between two cylinders which are defined by a housing. A first end of an actuating lever is operatively connected to the housing and a second end extends out of the housing and is adapted for connection to a steering means. A drive member supported by the reciprocating member provides a driving connection between the actuating lever and the reciprocating member.
