Abstract
In an apparatus for controlling an outboard motor having an internal combustion engine to power a propeller and a torque converter interposed between the engine and a drive shaft and equipped with a lockup clutch, it is configured to, based on input rotation speed and output rotation speed of the torque converter, calculate a speed ratio of the torque converter and a change amount of the input rotation speed, and make the lockup clutch ON/OFF based on the calculated speed ratio and change amount. With this, it becomes possible to appropriately make the lockup clutch ON/OFF, thereby improving speed performance.
