Our Marine Solutions

Steering Solutions

  • Palmer Johnson's CANnav steering system can be designed to meet any type of steering requirement that a vessel or operation may need.
  • CANnav utilizes proven CANbus technology as well as the latest proven electric, electronic and hydraulic components to ensure maximum control with long-term reliability and support.
  • System interfaces with Twin Disc EC300 control system to improve day to day operations, including a single push to command station capability.

Hybrid Solutions

  • Transfluid Hybrid Drive is a “true” parallel hybrid capable of operating in diesel or electric mode.
  • Capable of running in diesel, electric or “boost” mode which enables the simultaneous use of both the diesel and electric motor
  • Transfluid hybrid electric systems offer a smooth integration with an onboard power system; this allows the boat owner to review the electricity balance for on-board services, and optimize the use of batteries to replace part of on-board generators.
  • Transfluid Modular Hybrid System is a complete system solution with batteries, control system, cables, motors and modules to work in conjunction with your existing diesel engine and marine transmission.


  • When you outfit your vessel with new engines (re-power), you should also review your transmission.
  • Changes in engine power ratings could also affect the transmissions' ratings and gear ratio.
  • Evaluting the torque requirements will reduce the potential for transmission damage, early failure, and downtime.
  • A re-power engine is often a different size. This can cause offset and compatibility issues when utilizing the older transmission, not to mention added modification costs.
  • Older obsolete transmissions can add hidden costs when it comes to parts availability, torsional vibration issues, and downtime.
