Hello from Romania!
I have build two electric boats with Tesla modules but now i am close to powering up the Tesla LDU that i cut and modify in order to install it on a proper boat donor motor.
So what do you think about this LDU on a boat?

350 Volts. I have a lot of photos with the modified drive unit but the project has to be public only after an event, in about 2 weeks.
Thank you for all your work!
J.

it had a simple test at 306 V, does not allow power even with full throttle, plot ok for temp, direction, throttle (nissan leaf), it just slowly turns fwd/reverse ok, one error of overcurrent, but that was just precaution (50 amp), so i guess i have an encoder problem? thanks! i just love how it turned out, curious to see if interference because i cut the inverter bell, but i guess not
It has plexiglass. I have to test again tommorow

never seen the LDU look that small
Yes encoder problem. A/B swapped or not connected at all

Just AWESOME !
That just shows how easy it is to mod electric motors to other uses. Try doing that with a ICE car motor.
Very cool project and idea!
