Summary:To reduce porpoising while suppressing lowering of a speed of a vessel.SOLUTION: A system includes an outboard motor, a lift actuator, a sensor, and a controller. The sensor detects operation information indicating operation in a vertical direction of a stem of a vessel. The controller selectively determines a lift direction from a lift raising direction and a lift lowering direction, on the basis of the operation information, according to the operation in the vertical direction of the stem. The controller controls the lift actuator so that the outboard motor is lift-operated in the lift direction. The controller changes time to lift-operate the outboard motor between when the outboard motor is lift-operated in the lift raising direction and when the outboard motor is lift-operated in the lift lowering direction.SELECTED DRAWING: Figure 7 【課題】船の速度の低下を抑えながら、ポーポイズを軽減する。【解決手段】システムは、船外機と、リフトアクチュエータと、センサと、コントローラとを備える。センサは、船の船首の上下方向への動作を示す動作情報を検出する。コントローラは、動作情報に基づいて、船首の上下方向への動作に応じて、リフト上げ方向とリフト下げ方向とから選択的に、リフト方向を決定する。コントローラは、船外機をリフト方向にリフト動作させるように、リフトアクチュエータを制御する。コントローラは、リフト上げ方向に船外機をリフト動作させるときと、リフト下げ方向に船外機をリフト動作させるときとでは、船外機をリフト動作させる時間を変化させる。【選択図】図７
