Q: What is the lifespan or mean time between failures of the T200? How long can they run continuously?
A: 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. 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.
Likewise, these same factors affect how long a thruster can operate in non-stop, continuous use. Anywhere from a few days to several months of continuous usable life are realistic to expect depending on the exact operating conditions.
Thrusters do require routine maintenance, and this also affects how long parts will last. If components are well taken care of, they can last for many years. If they are abused and used in harsh environments, parts may wear down faster and will need to be replaced more frequently. For example, iron particles may be pulled from the water and collect inside the rotor on the magnets. This iron should be cleared out regularly to prevent corrosion and allow for proper operation.
We have recommended thruster maintenance guidelines in our Thruster Usage Guide to help get the most life out of your thrusters. In case anything does eventually need replacing, replacement thruster components are available here.
