X632/X432 Big enough to Push a DF26?

[sanyijr]

I realize keeping it simple may make it difficult to answer the question, but basically, I have a DF26 with a setup pushing around 29K RPM. To keep the amps low on the motor with a 4s setup, I am looking at possibly a X632 or X432 size prop. I tried the X637 cause I had one handy and the motor could not handle it. Temps were too high. Calcs seem to like the smaller 32mm props, but would I be wasting my time?.....

I suspect that the prop slippage will be very high on a hull this size, with resulting 'low' speeds. Years ago I used props that size on 20" to 22" boats.

Yes those sizes are to small on that size hull, I use x632 & x435 on 15" hulls.
