Keep the 17x29 4 blades and let us have a crack at them. I know we can improve the slip and speed numbers. |
Bret,, thats what i ment,,,, he runs 17 X 23 !!!!!!! To small .
But i need to actually have you take a look at my prop. My slip # is up like 18-20 % ????????? And the hull is perfect straight.:eek: |
Brett, or DD with a 1:54 ratio trans and an 18% over drive/drive "for round # sake" @ 6000 rpm engine speed, the out put of trans. would be 4000 that is to say: 3 rev. of engine speed produces 2 rev. of trans. out-put X 1.18 would produce a prop. shaft speed of approx:4720 with a 17x23 wheel and say a 10% min. slip what do you guys fig. for mph ? ps: just 4-kicks and giggles Ritchie Sutphen says that his boats, back in the day ran excellent w/Kaama surface drives ! Thanks again.

The # i figured out is around 82 MPH ??????????
But i could be wrong.:party-smiley-004: |
