    Prop help please

    Just purchased 1992 Nitro 190TF with Yamaha 150 ProV. Currently has a Ballistic 14 3/8 x 21P. Looking for a better performing prop. Thanks

    What is your GPS speed and rpms with prop mentioned? Motor height? Load? Elevation? Jackplate/ set back?

    Your 19ft boat/150 will never be a 60 mph boat.

    Finally ran the boat. Boat ran GPS 57 at 6000 rpm's. Out of the hole a bit slow but when I trim the motor up this boat takes off, wow. Pad to shaft is 5" below bad with Rome to move up a hole or two. Should I go to a 23P and move motor up some? Currently running 14.5"x21P Bulistic 3 blade.

    I would run a 23P Tempest Plus and raise the motor to 3.5 in below the pad and go up from there. Maintain safe water pressure.
