sim-, you are right: if we start the motor underwater, it never reaches full duty cycle. Prior to this video, we did try running the thruster underwater. The knob/potentiometer used...

I can confirm that changing TIMING_RANGE3 from 0x1000 to 0x2000 and reflashing the ESC worked! The thruster seems to have it's full duty cycle in water now. Thanks! I have...

So, we observed another thing while testing with TIMING_RANGE3 = 0x2000, the current the thruster draws is no longer periodic. For instance here is a scope-shot of the thruster (VR4)...
