Thread: Prop rpm, speed ?

Guys
Here's the question
I have a Honda 75 with a prop turning 6000 rpm, ( the correct top rpm speed), boat running 38, prop is 13.25x15 , 4 blade aluminum
I think the boat should run faster. It's a 17 G3 bass boat aluminum, total weight 1600 lbs with me in it and motor weight, gear.
My question is, if i try the same prop with a 17 pitch, will the boat actually run faster or will the drop in rpm, approximately 400, negate the assumed higher pitch speed?

Also, if I add weight up front, (say a 50lb sand bag) , will that let me trim higher and thus perhaps run the 17 pitch prop at 6000 rpms? Currently boat porpoises a lot when trimming higher.

Thanks
