DS Unit | Seastar (Teleflex-Morse)

Search product:

Overview

A Morse DS unit is a marine remote control component that enables a single engine’s throttle or gear shift to be controlled from two different helm stations, using a changeover system to select which station has control at any given time. It is part of a larger system that uses cables to connect the control levers at each station to a gearbox or engine unit.  

Dual Station Control: 
Allows boat operators to control the engine’s throttle and/or gear shift from two separate locations, such as the main helm and the flybridge.
Changeover System:
A selector unit works with the DS unit to determine which of the two control levers at the different stations is active. 
Integrated System:
It’s a comprehensive solution that ensures a seamless connection, preventing inconsistencies that can arise from mismatched components.

Example: Dual-Engine Flybridge Setup

You might configure:

  • 2× DS Gear Units (one per engine)

  • 2× DS Throttle Units

  • 1× Station Selector Unit

  • 8× 33C cables (two per function per station)

  • Custom-length cables (measured per routing path)

  • Polished chrome levers with adjustable friction

  • Selector positioned under lower helm

Features

  • Dual-function control
  • Station selector / changeover switch
  • Use of standardized control cables (e.g. 33C / CCX633XX)
  • Reduced cable bending / backlash
  • Single selector unit suffices
