Prop Suggestion Highfield 360 with Yammie F40

[morrisond]

Hi - We are getting 36.5 MPH at 6100 rpm out of a Solex 4 blade 10.8 Dia 12" pitch.

I'm thinking of putting a Yamaha Painted Stainless 11.25" 3 Blade 14" on it.

Looking for Top speed, this is for my Son - he likes bombing around in it and the faster the better.

Thoughts or suggestions?

I think you're on the money with the 11.25x14p that sounds about right
