A control function splitter for controlling a clutch and gearbox assembly and a throttle, particularly in marine applications. The splitter has main and override throttle shafts, and a clutch operating shaft connected to engine and assembly inputs. The splitter has a cam which moves axially to reflect control head signals. The cam has portions representing travel for gear engagement only with no throttle change, and travel between idle and full throttle with no gear change. A motion converting structure converts axial cam movement to limited clutch shaft rotation. An interlock between the clutch shaft and override throttle shaft prevents rotation of the clutch operating shaft unless both throttle shafts are at idle, and also prevents rotation of the override throttle shaft unless the clutch shaft is in neutral. The splitter reduces previous problems associated with non-lineality between a control head signal and the corresponding throttle output signal, and also improves positive "feel" of gear selection. Also, tendency of engine speed governor to cause speed setting to creep is markedly reduced.
