Need help selecting prop for Voracity w mods

[Indy27]

I have a Voracity that has a Leopard LB40WCJ-68MM and a Seaking 180 amp esc, I bought the boat set up like this with a custom prop that got damaged a few weeks ago and have no idea what prop it was, no marking but I know it wasn't stock. Tried a sharpened and balanced Octura m545 from the store here but it cavitates out the hole, any suggestions?

A bit hard to say without knowing what KV it is & what voltage you are running.

The Leopard part number you gave is for a water jacket. I ran an Octura 447/3 prop using the stock 1650kV motor on 6S for sport running. Also had luck with the m452. I used an ABC 1915 for just fast passes, but it was an aggressive prop and you could only run for about 2min.

Check out this thread for speed results and motor/prop combos. This is a good thread for modifications.

Well, I'm afraid I can't help you.
I've never run a set up at such high rpms.
Over 48,000 rpm is way too high for me.
Someone else will have to help you on this one.
