Recommended Propulsion Control
Systems for Northway Mathers ShaftBrake™

AD12 Pneumatic Propulsion Control - The AD12 is designed for high-performance workboats which have reverse reduction gears and diesel engines in the 500 to 10,00 horsepower range. The AD12 system features include:

  • Neutral delay proportional to vessel speed

  • Adjustable speed interrupt

  • Speed boost

  • Fixed orifice timing control

  • Manifold-mounted components

  • Timing for proper control of propeller shaft brakes

AD14 Pneumatic Propulsion Control - The AD14 is specifically intended for vessels with diesel engines in the 700 horsepower or less range. It's features are similar to the AD12 except that it's neutral delay is fixed, not proportional, and it has no speed boost. AD14 is an excellent choice for retrofit projects; it can be installed directly onto any existing pneumatic system.

Premium ClearCommand™ Electronic Propulsion Control
ZF Marine's ClearCommand™ leads the way in state-of-the-art electronic control technology. ClearCommand™ offers single-lever control of direction, speed and ShaftBrakes™ along with a host of reliability features and interface capabilities for such advanced technology as dynamic positioning via the Global Positioning Satellite (GPS) system.
