Hi Guys.
I have a 1200mm Black watch hull ( scale ) How ever I have ditched the traditional twin screw setup and gone with a 50mm Jet drive. my question is..

The jet drive came with 3 different props 3 blade, 4 blade and a 6 blade.

They all seem to be the same pitch just with more blades.
I am running a brushed setup with a massive Johnson 700 size ( I think )
what ever it is its big.. motor.

what prop will give me the best torque and allow the engine to rev more.
will having a 3 blade prop give me more topend then the 6?? How does it work?

Thanks

You got lucky as usually there's only one prop option, the one that came with the jet drive. Just like the rest of us find out using regular props, you have to find out which one the boat likes. Sorry if that doesn't sound like a whole lot of help but they build a jet drive and hope that it will work for you as there are a lot of variables depending on what it's going into.
