Abstract
A deceleration profile of a jet pump propulsion system affects the manually commanded deceleration of a boat by slowing the deceleration slightly in order to enhance steering capability on plane. In response to a manual engine speed command signal that commands a desired boat speed reduction, the engine control system slows the engine deceleration according to a preselected protocol or profile, and causes the engine speed to be maintained above the engine's idle speed for a predetermined time in order to allow a greater magnitude of water to pass through the jet pump of the propulsion system so that steering control is improved.
