I realized I never posted new performance data. As mentioned in an earlier post, the knotmeter was off considerably. Below are the new figures. This time around I also made sure the boat had come up to speed for a full minute or two before taking a reading.
KNOTS / TIME REMAINING / AMPS / VOLTS / RPM
2.4 / 14.6 / 6 / 50 / 720
2.8 / 8.5 / 10 / 50 / 920
3.7 / 3.6 / 23 / 49 / 1170
4 / 2.7 / 29 / 49 / 1290
4.6 / 1.6 / 47 / 48 / 1460
5 / 1.2 / 63 / 48 / 1730
Scott at Electric Yacht is generally pleased with the performance, but said he expected a little better. I was hoping to get 5.5 to 6 knots, which is close to the boat's theoretical hull speed. Scott said this could be approached with a swap of one of the pulleys transferring power from the motor to the outdrive. I may opt to do it in the off season.
