Abstract
In order to provide an internal combustion engine control unit for a jet propulsion type watercraft which can control an internal combustion engine so that a rider can perform risk avoidance safely, a controller 300 is provided, which increases the rotation speed of the internal combustion engine when the throttle open degree detected by a throttle open degree detector 22 which detects the throttle operation by the rider is a predetermined value or lower, and it is judged that the hull 1 is running based on the rotation speed of the engine 2 detected by the rotation speed detector 24, and when a steering handle angle detector 21 detects that the rider performs the risk avoidance operation.
