Sure sounds like something is not right with those amp numbers. I'm sure those numbers will greatly improve once you find where the problem is.

I had the opportunity to take out and commission Coincidence, a Victoria 26 with an Electric Yacht 100ibl system paired with a Sillette saildrive and 100Ah AGM battery bank. I'm using a 14" prop.
I wasn't overly thrilled--but mostly due to the nailbiting experience of trying to make it through a shallow channel to get to open water. It takes me a few times to get to know where the channel is each year, since the marker buoys aren't paced with any real accuracy.
There was a 5-8mph headwind heading out. Here are some readings I took:
KNOTS / RANGE / AMPS / VOLTS / RPM
w/ 5-8 MPH headwind
3.75 knots / .9hrs / 69A / 47V / 1770 RPM
3.5 knots / 1.2hrs / 54A / 47V / 1750 RPM
2.5 knots / 1.7hrs / 40A / 48V / 1530 RPM
2 knots / 6.4hrs / 12A / 49V / 1000 RPM
with tailwind
3.75 knots / .9hrs / 69A / 47V / 1750 RPM
2.5 knots / 1.6hrs / 43A / 48V / 1500 RPM
2 knots / 5.7hrs / 13A / 49V / 960 RPM
I made a slight adjustment then took these readings (still with tailwind)
2.5 knots / 2hrs / 35A / 48V / 1330 RPM
Overall, the motor ran smooth but seemed to be a little erratic at lower speeds (motor would rev up and down). Seems overly sensitive at certain spans.
I haven't been able to bounce these off Scott yet. I'll share these with him next week to get his opinion. This one of the first few EY installations with the Sillette saildrive.
The OEM engine was a 15hp, with effective hp probably closer to 10. I seem to be in that range with the new motor.
See project blog at http://v26coincidence.blogspot.com/ --but I haven't posted the readings yet.
