Automated Surface Drive Controls

Twin Disc MasterTrim™ automatically fine-tunes the trim position of a boat’s surface drives and trim tabs for maximum efficiency in changing conditions. This frees operators to focus on navigation—and resume full manual control at any time.

  • Four operating modes for varying conditions
  • Easily programmed preset positions
  • On-board diagnostics for monitoring and instant feedback
  • Tabs or interceptors required
  • Independent of EC300 but can be used with EC300 and EJS in the future
