Got 2 new propellers. 9.25 x 10. Original propellers 9.25 x 7.
Headed out to the water for another test
At rest, battery voltage measured at 53.1v. This test was heading into the wind
15.6A 6km/hr
23.3A 6km/hr
40A 7km/hr
52A 9km/hr
69A 10km/hr
88A water sprayed up in the wind, over the bow so give more throttle quickly
170A 17km/hr
176A 19km/hr
180A 21km/hr
210A 25km/hr
225A 27km/hr
273A 29km/hr
277A 30km/hr
Screen shot the speedo after we stopped. Max at 33, but mostly could only achieve 30km/hr
I wanted to see what one motor could do on its own so lifted the other motor and disconnected the power cable. Flat out at 13km/hr. Bear in mind though this was with one motor on the side of the boat so not a direct push. steering turned to get boat to track straight.
