I have a 98 Sea Stealth , with a 98 Yamaha 90. With the average load of boat, motor, gas, equip and people @ wot I'm at 4900-5000 rpm's. I have a 17 pitch prop. I have read that if I prop down to a 15 pitch I will gain around 400 rpm's which brings me to the high end of my motors operating range ( 4500-5500) My question is by gaining those rpm's will that inturn increase my speed?
