Original Series
Propulsion Units

Field-proven outboard propulsion for remote, rugged, and shallow-water marine operations

The Hydromaster Original Series are classic, mechanically driven outboard propulsion units, delivering up to 260 hp of reliable power. Known for their mechanical reliability, they have become a trusted solution in both commercial and governmental inland shipping and marine operations.

These fully self-contained units are designed for simplicity, durability, and easy deployment—making them ideal for vessels operating in shallow waters or where mechanical reliability is essential.

Control options

Remote control console

A remote console with a morse throttle controller to control engine speed and a joystick for full 360 degrees steering, alarms and indication and a control and monitoring panel for the diesel engine. The console and thruster unit are connected with multi-pin plug-and-play connectors and ample cable length for quick setup and deployment.

Unique engineering

The Swing Joint

The hallmark of the Original Series is the Swing Joint mechanism, which eliminates the need for a fixed steady bracket. This allows the unit to pivot, simplifying installation on various hull types.
