Abstract

PURPOSE:To prevent the reduction of the space in a vessel and the deterioration in the residence performance in the vessel by allowing the working oil sent under pressure by a hydraulic pump arranged inside an outboard motor body to circulate between the outside of the outboard motor body. CONSTITUTION:When fishermen advance to a fishing ground by using an outboard motor 10, and fishing machines 21 are used, a hydraulic pump 23 is driven by the operation of an operating lever 30. Therefore, the working oil sent under pressure by the hydraulic pump 23 arranged inside the outboard motor body 10A can be used for the fishing machines 21, etc. positioned outside the outboard motor body 10A. Therefore, a vessel 11 using the outboard motor 10 can be equipped with a hydraulic power source without specially installing the equipment for generating hydraulic pressure, in other words, without reducing the space in the vessel, and without deteriorating the residence performance in the vessel.
