These propellers have NOT been good seller as people seem to not like over the hub props (In big boats all like over the hubs). But the people that have bought this props like them like crazy. I think these props are the next "BIG SECRET".

I'd like to try one of these on my SLT too. Got a 70ces on the back. I reckon an 11x21 or 22p would work well. Is the free prop competition still going Ron? ;)
If we can prove they work I reckon you'd have a que for them

i tried rowans ,it measured 17.7 and it did 56 mph @ 6760rpm with 175kg crew and 0.5* of positive trim. we should have tried some different trim settings.
it did take a while to get out of the hole a bit of cupping would help, i can't wait to try it again when he gets it back fro yan.

I have an Edge 3 (11.75"?) x 19 and besides having some bow lift, it ran really well on my Aquarius. I was surprised how much it didn't slip on hard accel from a stop. Maybe it's bc the thundercat is so light that the prop still gripped enough in the presence of exhaust gas.

Ron, what are the effects of the barrel (through hub) beyond getting the exhaust gas past the blades from a stop? Think the barrel is a source of parasitic drag in lieu of over hub exhaust? Would it affect how high a prop would run without blowing out? I wish there was a book for high speed prop learnin'.

Pics for the fun of it...
