Propulsion system of boat

Abstract

A propulsion system of a boat includes: a propulsion machine including a drive source, and a propulsor configured to generate thrust with power transmitted from the drive source, the propulsion machine being provided on a hull; a trim angle adjuster configured to adjust a trim angle of the propulsion machine with respect to the hull; and a controller configured to control the trim angle adjuster, in which the controller is capable of conducting hump control of causing the trim angle adjuster to adjust the trim angle to suppress an inclination in a pitch direction of the hull, and in a case where a boat speed of the hull falls within a preset speed region, the controller enables conducting the hump control.
