ABSTRACT:
An outboard motor steering system includes a hydraulic fluid supply mechanism connected to the steering hydraulic cylinder to supply hydraulic fluid thereto disposed in a space formed between the stern brackets and the swivel case. In other words, since the hydraulic fluid supply mechanism is incorporated into the outboard motor as a unit, the structure can be made simpler than that of the related art and the number of parts in the entire system can be reduced and moreover the work of installation into the boat's hull can be simplified. Also, operating efficiency is improved for an electric motor serving as the source of driving force for a hydraulic pump that supplies hydraulic fluid to the hydraulic cylinder used for steering, and power consumption is reduced.
