I'm running a dasa 800cc PV motor with total loss and pfp. I'm running a solas 144mm mag pump what would be the best prop to run. Thanks Chase
Freestyle What's the right prop?

I ran a dasa non pv 802cc with total loss, power factor and solas mag 144. 11/17 hooker was perfect for me.

I would think 11/17 would be about right if I had to guess.

did you ever try the 11/17 hooker i traded you?
it was way too much for my 771 but the 9/15 you traded me works mint!

Just tried it yesterday but I have a lot of tuning todo so don't know if its the right one yet.

When a prop is cut back what exactly does that mean? I'm assuming the prop is put on a lathe and the trailing edge is cut back 3mm for instance? Is it to set back the prop in the pump to aid in loading? Never knew figured I'd ask

I'm using the ski for flat water freestyle and that's it just looking for the most pop off the bottom

you cut the threads back so the prop screws on farther and the trailing edge blades are closer to the stator veins in the pump. the smaller the gap between the 2 , the better. less power loss, but easier to chew your $hit up with rocks or debris.

what do you know, apparently you just sell junk hahah.
Thanks mark. But is the material just removed from the inside hub not the actual blades? And follow up question is why not cut it back enough to where you also have to trim trailing edge of blades in order to not catch vein section of pump? What's the most someone has cut back a prop? Mine is 3mm...

Just the inside hub is cut. You don't cut the vanes back. Hooker imps are set back quite a bit.

one more try since I asked this question(in another thread) before but seems that trivial B.S. sometimes takes a roll here instead of good clean concise information but what exactly does the pitch stand for? I understand it to a point but just dont know what the numbers mean? Is it the degree of the blade 1mm from leading egde and 1mm up from trailing edge? for example 11/17??
not threadjacking but I could see how this could also help the OP on props as well as others

11/17 is variable pitch. pitch is measured in degrees. 11 is the leading edge and it ends up 17 degrees at the trailing edge. its only 11 for a fraction of the blade and the # quickly moves up. like kawi 650 skat props were straight pitch 15, 15.5, 16, 16.5. not variable. i was told by pete debaghian that if you take the low # & high #, split that in half, thats kind of what you get for the pitch. the bigger the #, the bigger the bite of water it takes. too big a prop and an underpowered motor cant turn it. too big a bite for the motor to hit max rpm so you actually lose top speed. thats why sometimes when you bore the nozzle, you get more top speed, cause the motor can now hit max rpm.

try using the tail rotor prop from your Rc helicopter, now your talking some serious pull, thred bump
