Hi @bluba -  
Welcome to the forums!

A T500 may be a better choice for an AUV if the nozzle is removed - the standard design is optimized for ROV use (static or low speed thrust.)

Blue Robotics has no collected performance data for the non-bollard thrust cases.

You can find some detail on the props [on this thread](https://discuss.bluerobotics.com/t/flow-rate-s-for-t200/4117/9), but the 3D cad model _does not_ reflect the true geometry of the propeller, which is considered proprietary. Sorry for the news!

Maybe [this](https://www.printables.com/model/917540-m500-weedless-propeller) prop is worth a try?
