This iron should be cleared out regularly to prevent corrosion and allow for proper operation. For example, iron particles may be pulled from the water and collect inside the rotor on the magnets. If they are abused and used in harsh environments, parts may wear down faster and will need to be replaced more frequently. If components are well taken care of, they can last for many years. Thrusters do require routine maintenance, and this also affects how long parts will last. Anywhere from a few days to several months of continuous usable life are realistic to expect depending on the exact operating conditions. Likewise, these same factors affect how long a thruster can operate in non-stop, continuous use. Factors such as water quality, sediment density, particle size and composition, throttle level, operating voltage, etc., all play a large role in affecting thruster longevity. It depends! Because our customers operate in varying conditions across a wide range of use cases, there is no one expected total lifespan that would apply to all situations.

Note that nominal operation at 12-16 V is recommended for the best balance of thrust and efficiency, though operation at up to 20 V is allowable. *Values limited by ESC used to drive thruster.

A sensorless brushless electronic speed controller (ESC) like our Basic ESC is required to run the thruster in all situations. The core motor design is a three-phase brushless outrunner motor, similar to what you’d see on drones and RC airplanes, but optimized for underwater use. The design is compact and has a minimal number of parts so that we can offer it at an affordable price. It eliminates the need for shaft seals, magnetic couplings, and air- or oil-filled compartments, making the thruster naturally pressure tolerant. It allows the motor to be water-cooled and the plastic bushings to be water-lubricated. The fully-flooded design is unique compared to thrusters existing before the T200. The thruster body and propeller are made from tough polycarbonate plastic and the only exposed metal components are made from marine grade 316 stainless steel. The T200 Thruster uses our patented underwater thruster design consisting of a fully-flooded brushless motor with encapsulated motor windings and stator as well as coated magnets and rotor.
