T Series hydraulic tunnel thrusters are compact and easy to fit units that can be supplied complete with steel, aluminium or composite tunnels, pre-drilled ready for installation. The thruster hub units are protected by twin shaft seals on each propeller shaft, and a single shaft seal on the vertical input shaft. The tunnel thruster uses high torque spiral bevel gears and twin con-tra-rotating propellers to develop a high thrust to tunnel diameter ratio.
OMS is the manufacturer of all OYS Thrusters.

OMS Fixed Drive Leg
Electric
D Series fixed drive legs are a range of the most compact, lightweight and versatile units available on the market. They have been developed from the same technology used in our range of steerable and retracting thruster and drive designs.
The Drive leg can be connected via a coupling to a traditional diesel engine, hydraulic or electric shaft motor. The legs are designed to be simple to install, easy to maintain and provide a compact solution. Designed to work with large fixed or folding props the OMS Drive leg is suitable for sail and powerboat applications. The standard leg comes with a 1:1 ratio however OMS is able to customise the gears, powering and length/depth of leg to suit.
