Here, let me fix this for you!
Seriously through, there is no downside to getting your boat operating in the RPM band where it's supposed to. If it'll run at the top of the RPM range when light, it will perform decent when loaded, you'll lug the engine less putting less wear and tear on it, your fuel mileage will be better, you'll have better hole shot and top speed, and a better boating experience. running the wrong prop and engine height is like ordering a $200 T bone a the fanciest steak house and putting ketchup on it!
Also, don't trust your dealer, many don't have a clue how to property set up a boat. Often times they just slap one on that is close or go with the manufactures recommendations which is usually an ok setup for the masses. However, everyone loads and uses there boat differently and getting it set-up specific for how you use and have your boat loaded will provided you a much more satisfying ownership experience. Heck, even within a given prop, such as a Bravo FS or any other, the manufactures have set them up to provided a decent experience for a wide range of hulls and performance characteristics. If you really want it dialed in, that's where a custom ground wheel from a reputable performance shop such as DAH or Croxton propeller comes in. basically you find the best stock prop and pitch for you boat, then have them balance and blue print the print the prop, they'll shave some weight, sharpen the leading edges, add cupping, re-pitch, and possibly flar the barrel or add additional vents pending exactly what and how you want your boat to perform. food for thought.
