Even if you are fire-walling the throttle out of the hole (which I agree with the others is not good) you won't turn up full RPMs. The props/engines are just too loaded at that point. You won't see full RPMs until the boat airs out on plane.

As for the prop size, 22 is way small. As stated above, 26p was factory stock. 271s have always been notorious for bad planing. Friends have an 02, 502, 26p. It blows the prop out bad on take-off. You have to nurse it up on plane. Very slow to plane but not because of too much prop. It just looses bite. But, once planed off it comes up to 5000 easily.

If you are looking for serious more power for your 271 with 496 Mag just change ECM and camshaft and make it 425 HP or add a Raylar Kit and gain up to 225 HP without supercharging

He needs a prop first.
