If you want some help post your WOT RPM and WOT MPH and we can run some numbers for you. Julie |
Just getting the boat together. The motors are 875 hp 810 ft t at 6300 rpm. Trying to spin a prop around that rpm. Drive ratio is 1.5 Thank you, Chris

Whould you know price comparison of Arneson VRS#6's? thanks!
The Arneson kit is complete and includes everything from the bell housing rearward. Lot less $, far less weight along with lower hp loss and of course more speed. |

I would say around 112 MPH with a 32P 5B Semi-cleaver style propeller, like ours. I don't know if your drive is the correct height, for a 6B propeller.
I can tell you that the newer Donzi's run phenomenal with a 6B! Julie |
