摘要： 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.
