Anyone using a 15 degree leading edge on your prop?
Looks like this is the ticket to better holeshot and acceleration. I'm thinking of using a 15/22 or 15/23 Skat with my mods. Any suggestions? Comments?
Top speed is secondary...I much rather have better holeshot and acceleration. Last time I did 60+ mph in Hawaiian waters I took a drink and fractured a rib. Just too much chop.

I'm running a 15/25 but this is on my seadoo pump setup and I still have a few blips of cavitation when I take off from a standstill. Desperado is trying to work on a few things in my map with cavitation control.

12/20 with a 160mm pump. E1. MoTeC. No cavitaion.

In my opinion, there is no reason to NOT use a 15 degree leading edge. I had my stock prop opened up to a 15/19 and it runs great. Not perfect, but would be even worse with less of a leading edge to grab more water and load up the trailing edge of the prop. You basically have nothing to lose, except some cavitation. lol
I also think a 15/21 Skat swirl is a great place for you to start, you can always pitch up the trailing edge a bit if you need to to get the RPMs where you want them.
If he doesn't chime in, shoot Tommy Jordan a PM and see what he thinks. He is extremely helpful with prop suggestions among other things. He has helped me a ton.

Unfortunately, I do not have the luxury of "traction control" like you Motec guys. Motec users could probably use any prop they wish and tune out any cavitation. I have to find the right prop to get rid of any cavitation.

I'm curious as well if he is using traction control.

I'm running a 15/23R and I do have some cavitation during take offs since I added the 1000CC injectors, three bar map sensor and RIVA WATER BOX...
