i did some runs this weekend in my ms geico. have the stock motor with a t120. Tested 3 props a b225 a m445 and a x645 that I modded to a m series. the 225 pulled 90 peak amps and seemed the slowest which i believe is because the prop has too much lift and needs some cupping.
Next the m645 pulled 98 peak amps and seemed to be the fastest.
the m445 pulled the least out of the three at 85 peak amps and didn't seem far off the 645.
So the question i'm asking is... Can i expect a 10% drop in amp consumption if i were to bar cut say the x645 dropping amp consumption to around 90 amps. This will be my first attempt at a barr cut. Is there an approximation for how deep/wide i should make the cut.
Hopefully one of the prop gurus will be willing to share some secrets on prop modding. I have a pitch gauge on the way so hopefully you guys can give me some tips to get started.
Darin if you happen to read this. I'm getting 98 amps on a 645 i remember you saying you ran a 230 and it still wasn't enough so you went bigger. My watts up meter is limited as it doesn't tell me an average amp consumption but only the peak values. Boat seemed fast, but not fast enough.
I was wondering if you had any eagle tree numbers on what props in this range are pulling at wot. I feel like with numbers that high im gonna be using too much battery and the motor will be getting pretty warm with the california sun beating down in mid june.
