I just measured my pad height on my 94 284 pro with a 94 150 evinrude it has a 5" hi-jacker jack plate and a 13 1/2 x 25 renegade 4 blade. The pad measured in at 5 1/8 I'm getting 59 gps at 5100-5200 rpms fully loaded, What I'm wondering is if I'll gain anything by rasing the motor or should I just leave it as is? It dose have a great holeshot. I also have a 23" 3 blade I've never tried. any input would be great. Phil C
