Abstract
A marine steering system for an outboard motor (M) has generally parallel cable devices (13, 13A) extending between a steering wheel (8) and outboard Motor (M) of a marine craft. The cable devices (13, 13A) include a pair of fixed control cable housings (14, 14A) and a pair of control cables (16) secured to slidable tubes (28) received within the housings (14, 14A) for sliding movement for steering the outboard motor. An inner control cable housing (14) is externally threaded and the outer control cable housing (14A) has a smooth outer peripheral surface. An internally threaded lubricating nut (52) is threaded on the inner control cable housing (14) for lubricating the telescoping tube or tubular member (28) secured to the control cable (16). A second lubricating nut (60) has a smooth inner bore defining a large diameter bore portion (62) to receive the outer control cable housing (14A) and a smooth small diameter bore portion (64) to receive the sliding tube (28) secured to the control cable (16). A set screw (82) secures nut (60) to the outer control cable housing (14A) and O-ring seals (68, 72) engage in sealing relation the outer cable housing (14A) and sliding tube (28).
