19 or 21 pitch.

Inline or V6?
" gets a bit rough at 45" how so? If the boat does't handle well, going faster just raises the risk.

Re: 19 or 21 pitch.

I'd go with a stainless four blade 20 pitch. The four blade will smooth out the ride, and still get you out of the hole. It'll give you more speed and lower the RPMs
Good luck, Chris
