Injam,

Like Wayne said, the right prop for your boat is going to be a bit of an
experiment exercise. If you are buying a new boat, confirm with the dealer
that he will assist you in obtaining the optimum pitch after you take
delivery and have some experience with it. A 25 hp difference in engines is
not going to be a huge factor. Things like how you load the boat, how many
people typically ride with you, etc. will probably have more of an affect.
The simple method is to determine what pitch allows your engine to achieve
it's recommended maximum RPM at WOT. I think you will find that a
compromise of sorts will be required though because the ideal pitch will
change, again based upon how you load the boat.

I had an old Century I/O years ago and had two props. I used the higher
pitch when I was just cruising by myself or with one other person. If four
or more people showed up for a ride, I changed the prop to a lower pitch.
