Hello everyone, I am new to scream and fly and I am seeking some help. I have a 1986 Bass Hawk 17 with a 1986 Johnson GT 150 on a 6" Jack Plate and running a 23P Renegade 4 blade. Right now I am running 57-58 mph turning 5300 rpm's. My motor is 4.5" below the pad. Can I go higher and what else can I do to get a little more speed from the ole girl. 60+ maybe.
