Just tried out the X430 prop after sharpening and balancing it. Unfortunately the water on the pond was still - not good for speed. Anyway I find it hard to tell how fast it's going by just looking at it. I don't think it was going any slower than with the stock 32 mm plastic prop though. The run time seemed a bit shorter than usual and when I brought it in everything was a bit hotter than normal although not really hot. This was surprising because I thought the smaller 30 mm prop would pull less amps, everything would be cooler, and I'd get longer run times. Perhaps the pitch of the X430 is greater than the stock prop. Also the drive dog had been tightened much harder on the shaft indicating the prop was putting more torque on it. I might try raising the motor slightly to reduce the drag of the lower unit.
GRK65, did you ever get to try that X632 on it?
