Thrustmaster’s deal with DOEN brings waterjet manufacturing to the United States. Marine propulsion and thruster manufacturer Thrustmaster of Texas, Inc. announced a deal earlier this year to acquire the technology of DOEN, an Australian designer and manufacturer of waterjet propulsion systems. The deal is significant in that it makes Thrustmaster the only producer of commercial waterjets in the United States, helping the Houston-based company to expand upon an already strong line of commercial marine propulsion offerings.
