    • A power steering device for steering an outboard engine on a small boat has a hydraulic cylinder unit for angularly moving a steering arm of the outboard engine, the hydraulic cylinder unit having a piston rod connected to the steering arm, and a directional control spool valve for supplying a hydraulic pressure to the hydraulic cylinder unit to move the piston rod. A control cable controls the directional control spool valve in response to operation of a steering wheel. The control cable has a core having an end coupled to the piston rod and a sheath covering the core and having an end coupled to the spool of the directional control spool valve. The hydraulic cylinder unit has a cylinder divided by a piston into a first oil chamber through which the piston rod extends and a second oil chamber remote from the piston rod. The directional control spool valve has an oil passage which interconnects the first and second oil chambers when the directional control valve supplies the hydraulic pressure to the second oil chamber.

    • A tilt cylinder for tilting an outboard engine has first and second cylinder chambers. A pair of on/off valves is movably disposed in respective fluid passages connected to a hydraulic pump and the first and second cylinder chambers, respectively. The on/off valves are operatively combined with respective shuttle valves which have respective oil passages in facing relationship to the on/off valves, respectively, and respective ball valve bodies for selectively opening the oil passage into communication with each other. When the hydraulic pump is actuated to develop a working oil pressure buildup, one of the on/off valves is opened by the working oil pressure buildup to establish an oil supply passage from the hydraulic pump to one of the first and second chambers, and the other of the on/off valves is opened by the coacting shuttle valve which is moved by the working oil pressure buildup to establish an oil return passage from the other of the first and second chambers to the hydraulic pump. The shuttle valves have respective auxiliary passages communicating with the oil passages, respectively, and the oil supply and return passages, respectively.

    • A steering system for a boat propelling apparatus is disclosed, which includes an operation unit, a steering piston-and-cylinder assembly and an operating fluid switching unit. The operation unit causes a steering arm of a propelling unit to be operated with operation of a steering wheel installed in the boat. The steering piston-and-cylinder assembly is connected to an operating fluid supply pump and a drain tank and capable of being supplied with operating fluid. Its piston rod is coupled to the steering arm. The operating fluid switching unit is disposed between the steering piston-and-cylinder assembly on one hand and the operating fluid supply pump and the drain tank on the other hand, and it switches the flow of operating fluid with the operation of the operation unit. It includes a switching section having a poppet valve coupled to the operation unit. The operating fluid switching unit includes a switching section and a normally closed drain control section. The switching section switches the flow of operating fluid directed form the operating fluid supply pump to the steering piston-and-cylinder assembly. The drain control section controls the flow of operating fluid directed from the operating fluid supply pump to the drain tank, and after the lapse of a predetermined period of time from the instant of start of the operating fluid supply pump it is closed, whereby operating fluid is led to the switching section only. The operating fluid supply pump is operative at all times, and it leads operating fluid through the drain control section to the drain tank in the inoperative state of the operation unit while leading operating fluid through the switching section to the steering piston-and-cylinder assembly in the operative state of the operation unit.

    • A hydraulic pressure mechanism for angularly lifting and lowering an outboard engine includes a hydraulic cylinder unit comprising a piston assembly and a hollow cylinder, the piston assembly being slidably fitted in the hollow cylinder and dividing a hollow space therein into a first oil chamber and a second oil chamber, a tank for storing working oil, a pump for delivering working oil from the tank to the hydraulic cylinder unit, and a spool valve for supplying working oil from the tank through the pump selectively and exclusively to the first and second oil chambers, thereby to cause the piston assembly and the cylinder to move relatively to each other for enabling the hydraulic cylinder unit to tilt the outboard engine. The cylinder has a tilt-limit hole defined in a side wall thereof in a range in which the piston assembly is slidable in the cylinder, so that the tilt-limit hole can be closed by the piston assembly thereby to limit sliding movement of the piston assembly with respect to the cylinder under at least external forces applied. The hydraulic pressure mechanism also has a valve for bringing the tilt-limit hole exclusively into communication with the tank through a flow passage.
