Abstract
Provided is a boat engine idling revolution number control device, which includes a control unit () for performing control so that an engine revolution number converges to a target revolution number based on a result of detection of an engine state. The control unit includes: a decelerating running determining section (); and a running-load correction calculating function section () for calculating a running-load correction signal for correcting a basic torque rate based on the result of determination by the decelerating running determining section and a shift position state detected by the neutral switch. The running-load correction calculating function section resets the running-load correction signal to zero when detecting, based on a behavior of the engine revolution number after the running-load correction, that the engine revolution number is larger than a threshold value calculated based on the target revolution number and the engine revolution number increases.
