Another set of propellers. 9.5 x 13. Stainless steel. There is not a lot of visual difference between the 9.25 x 10 and the 9.5 x 13.
Made some changes to the steering setup. We now have a temporary forward control.
Numbers for the stainless steel props. Probably not what they should be. The cav plate was borderline with the smaller props. With the slightly bigger diameter stainless steel props, they cavitated a little. Achieved similar speed with less amps.
15A 6km/hr Planing at this speed
31A 7km/hr
45A 9km/hr
50A 10km/hr
70A 11km/hr
100A 16km/hr
120A 18km/hr
160A 20km/hr
170A 25km/hr
200A 28km/hr
250A 30km/hr
256A 31km/hr Max throttle could only get 256A
The highest speed we saw was 31km/hr, but mostly could only get 30km/hr max.
Here is a comparison of the 3 propellers
