Is it a 48V system ?
(Better to calc the consumption in Watt.)

I am not sure but it almost seems like the meters need to have a few cycles of the battery to calculated the percentage charge . not sure just observation

I am working on a larger write up but thought I would share some results from my first run.
Main concern: it was too loud! I think the cutlass bearing was too worn when I started The project and there was too much motion up and down. I think that the shower is aligned with the motor well, but dad it's at to much of an angle with respect to the Cutlass bearing. This is also putting pressure on the stuffing box.
So I need to adjust the angle.
But I was able to get some preliminary numbers
The boat is a 1979s 30 foot fiberglass hulled ketch (Rawson 30). Hull speed is 6.9ish
Power consumption is almost logarithmic, as expected ~20a @ 3.2kn, ~55a @ 4.5kn, 115a@ 5.5kn
Don't yet know how much to trust that meter.
What do you guys use to monitor battery capacity? I have a little meter that I ordered from Amazon but it recorded 100% wow at the end of the run and when I plugged in the charger, it recorded between 50 and 75% unfortunately the charger doesn't give me a better number than that.
