boat prop

[alex]

i have a 90 bass tracker 1800 tf with a evinrude XP 150, the power head has just been rebuilt and the boat will only run around 51mph, i have a 14x24pitch on it, should this boat be running any faster than what it is?I have been told that the pitch on it is wrong and do not want to start spending alot of money on new props if this ain't the problem. thanks Alex

What RPM's are you turning at 51mph?
You also need to know what your engines operating range is (ex.5000-5600)?

Alex I have a Ranger 185 with a yam 150 on the back and I top out at around 55mph gps so may not be to far off the mark

before i had the power head rebuilt it turned around 5600 to 5800 and now it's only turning around 5200 to 5400 and not really sure why it wont turn no more and thanks for the offer on the prop not sure if it will help but i'm willing to try any thing the one thats on it now is a raker 14x24

Alex, I have a 92 18ft Ranger with a Faststrike 150 and it tops out at 62, always has at that speed. Has a Raker prop but I couldn't find and size markings. It should give you an idea of what speed to look for.

hey ells look in the center at the spline that's where mine is and yours might be there too,every one i have talked to says it should run around 60mph

You may want to check throttle travel. Make sure it is traveling to the full throttle position. Could be that simple as they could have set incorrectly at the shop.

i checked it and it looked ok but that don't mean anything(lol)i work on big trucks and cars...not much of a boat mech. but i am learning
