I run at 1650 to 1700 rpms and get 6.3 knots. Any more and my wake starts going up dramatically as does fuel burn.

1800 to 1850 if I need a half knot to make a bridge.

I usually run 1650 to 1750 and get roughly 6.5 knots in no current.
I have been known to run 1900 at times, but I prefer to keep the rpms down.
Not a fuel thing for me as there's not enough difference to even consider, just thinking longevity.

I run at 1700 which gives me 7 knots using a 4 blade prop on a Ford Lehman 120. Higher rpm’s just increase the noise level.

Should have room for another 100 to 200. Wont hurt to try it.
Make a simple rpm/speed table 100 rpm increments. When you get to where 100 rpm boost only raises speed 0.1 knot, no point in going further.
