<p>An object of the present invention is to provide an outdrive unit (3) that allows space to be saved in the positioning of a hydraulic circuit for trolling, and enables easy maintenance of the hydraulic circuit for trolling. The invention provides an outdrive unit (3) mounted outside of a boat, including: a propeller (4) for propulsion; a hydraulic clutch (8) that controls driving of the propeller; a transmission mechanism (71,72,73,731) that transmits drive power from the hydraulic clutch (8) to the propeller; a hydraulic circuit that operates the hydraulic clutch (8), the hydraulic circuit comprising a switching valve (101) that switches a rotational direction of the propeller (4), a pressure-reducing valve (102) for trolling that reduces a pressure of a pressurized oil supplied to the hydraulic clutch (8), a filter (103) for the pressurized oil introduced to the pressure-reducing valve (102), and a hydraulic pump (21) that supplies the pressurized oil to the hydraulic clutch (8); a housing (32) that houses at least one of the hydraulic clutch (8), transmission mechanism (71,72,73,731), and hydraulic circuit; a base (10) on which the switching valve, pressure-reducing valve, and filter are mounted, the base being detachably mounted in the housing (32).</p> |
