That old Gancia still winning races - amazing! Well the OL with the Brits should when dialed in run circles around her finally after all these years!
RIK - let's play here now that I know you can do that with the box.
Here's what I'm going to do in my mind, purchase a single engine 29' Fountain. I will take out the gas engine and drop in a 480Hp Cummins "B" diesel. I want to install your Arneson Bravo conversion and I want a prop rpm of around 4,500 rpm so a OD of like .75 -.80 whatever you have in that range. We'll use the Velvet/72 series trans direct drive.
Question do you think I can swing a 16" dia with enough pitch to use all the power or do we need taller gears - my objective is not to go over 16" dia. I'll explain why, the little boat requires a lot of throttleing if we do open ocean racing like Charlie is setting up and if we attempted a few records here and there. The little dia props let me throttle easier, the engine will response quicker as the OD gears, you know work like Jake Brake - LOL.
I also know from Fabio, (seen it first hand) the power the diesels can exert is tremendous they have torque, the big Dia bites and can break while the small dia allows for a factor of built-in slip to cushion everything.
I'd like smaller dia down to 15" but don't how that might work, your thoughts and advice are welcome as always
How fast do you think she can run light on fuel set-up like I desribe?
