The 2554 dual function pneumatic control head provides single lever control over ship direction (ahead and astern) and engine speed. The pneumatic signal can control either a hydraulic reduction or pneumatic actuating gear. The 2554 also comes with side scales and internal light sockets for illumination. 

This control is typically intended for vessels ranging from 40' to 175' (12m to 55m), and all pipe connections are 1/8" NPT.
