Abstract
An automatic throttle adjustor system for a power boat which is operable to return a carburetor throttle valve to an idle setting from a user-selected setting when a sensor mounted on a bottom of the boat is about to leave the water, and which is operable to return the throttle valve to the user selected setting from the idle setting when the sensor is again submerged in the water. The system includes the sensor, a controller, an actuator, and a throttle linkage. The sensor supplies signals to the controller indicative of whether the sensor is submerged or airborne. The controller uses the signals supplied by the sensor to switch the actuator between a normal, activated state, in which the throttle valve is at the user-selected setting, to a deactivated state, in which the throttle is moved to the idle setting. The throttle linkage includes an element which is in a first position when the actuator is in the activated state and which moves to a second position when the actuator is deactivated. Switching of the actuator between the activated and deactivated states moves the element between the first and second positions and, accordingly, moves the throttle valve between the user-sele…
