the one that allows it to turn about 5500 rpm with a medium load. most likely something about 13 x 17

Here's some benchmarks for you. My 88 SPCL on a similar boat turns 5600 RPM with a 15"p prop and 5100 RPM with a 17"p prop. Both SS. I'm guessing a 17"p SS for yours.

I just picked up a Raker prop,and picked up 4 mph,the motor is a 1993 Johnny 120. My r's are a bit low though,,only 5200.
