ABSTRACT:
An engine control linkage for connection between an engine output control and hand and foot controls. The linkage includes first and second elements interconnected by a pivotable link, motion being arranged to be transmitted from the hand control to the engine output control by non-pivoting translational movement of the link. A connection is provided between the foot controls and the link for pivoting of the link relative to the first and second elements to vary the effective length of the linkage and thus override the engine output setting of the hand controls.
