Home > Products > Tunnel Thrusters > Engine Driven

Tunnel thrusters for direct engine drive are available in the range of 250 to 3,000 HP.  The engine must be provided with a marine gear with a reduction ratio to match the input speed of the thruster.  A cardan shaft connects between the output shaft of the marine gear and the input shaft of the thruster.  Many horsepower and RPM combinations are available.  Please contact our sales department for your application. Some models have ABS Type Approval.

For more information, request our AutoCAD drawing CD-ROM.
