I've got a 10' gwinvader with a 70 horse and 15 in. prop. I'll be getting into that prop testing phase this summer, and know how the process works with the RPMs, gear ratios, speeds, and etc. But, my question is this: does anyone know if someone makes high pitch props for smaller outboards like mine? maybe 20-24in.? I have no idea if it'll need something that large, but i'm guessing i'm overrevving pretty good right now, so.....any help would be appreciated.<br /><br /> Thanks, guys!
