I do mainly knee-boarding, wake boarding, surfing and an occasional slalom run. i am leaning towards the 1433. So how much speed am i going to lose top end and will the fuel burn be greater with the 1433?
Compared to the stock OJ prop, you will not lose any top end with the 1161 and will lose about 2-3 mph with the 1433. You will burn more fuel with the 1433 but you will have a lot more holeshot with the 1433 over the 1161. I tested the 537 and the 1847 which are identical to the 1161 and the 1433, respectively, other than the cup which is a minor tweak.

How much ballast do you run while wakeboarding and how many people do you typically have on the boat? The 1161/537 is great with stock ballast and 4-6 people on the boat. If you run more than stock ballast and often have 6+ people on the boat, I would go with the 1433/1847. I had the 537 for a while which was a huge improvement over the stock OJ, but with about 1400#'s of ballast and 6+ adults on the boat, it struggled a bit to get up on plane. So I switched to the 1847 and have had no issues planing out with a boat ful of people and the ballast full.

Below is a link to my prop test post that Grant is referring to. I think you will find the data there that you need to decide which prop is best for you.
