25 at 2100 is pretty fast. I’m closer to 22 with 4 blade and same hull as you. ------------- Tom 94 Ski Nautique Open Bow 351 with Carb 95 Double Decker Aqua Patio with 50hp Honda (3 carbs). |

He'd probably wonder what brand and size is on it right now to give those numbers. He'd probably also wonder if the tach is accurate and the speed is GPS verified, since like Tom said, 25 mph at 2100 rpm is pretty fast now with whatever is on it

I don;t think youre going to save what you think you are going to save. if you get the rpms lower, the manifold vacuum will be lower(numerically) because one still has to burn x gas to do x work ------------- "There is nothing, absolutely nothing, half so much worthwhile as messing around with boats...simply messing."
