Abstract
An object of the present invention is to provide a trolling device which can reduce the operational force of a trolling lever while the oil pressure setting of a marine gear is raised to increase the capacity of a transmission torque. The trolling device has a pressure reducing valvefor reducing clutch oil pressure and a low speed valvefor adjusting the spring force of a pilot springof the pressure reducing valvein conjunction with a trolling lever, the low speed valvehaving a protrusionwhich extends inside a coil spring constituting the pilot springto the side of the pressure reducing valveand comes into contact with the pressure reducing valveat least when forward and reverse clutches are fully engaged, the protrusionhaving a drain oil passagewhich comes into communication with an orificewhen in contact with the pressure reducing valveduring trolling and discharges drain oil from the orifice
