I have a 14 foot flat bottom boat with a 99 model 25 horse Merc and has a 16 pitch 3 blade aluminum prop. With the load that I normally carry it has trouble planing out. Once planed out it runs along fine w/good rpms. Can anyone tell me how far down I should go in pitch to get better planing perfomance without going too high in rpm's? I'm fairly ignorant when it comes to props, I just that going down in pitch is like going with a lower gear ratio in the rearend of a car. Thanks in advance.
