If you visit the props section here, it looks like a selection from 9"-12" pitch available.

The best prop for your setup depends on your present prop and your performance.
if you read the stickys at the top of the prop forum and get us as much info as possible
we can help make an informed selection.
To do this right you will need something like a Tinytach and a gps for speed.
For the best performance and the health of your motor you need these things.
Your motor has the old style gear case the prop size should appear near the base of the blades or on the hub.
Prop size is written diameter X pitch. Pitch is the key measurement.

Just wondering; we have a 58 Lonestar 15 ft bare utility that is probably a similar boat. A deck forward with lockable storage under.
The bottom at the stern is flat with a slight curve at the chine. we had a 25 on it and it was pretty fast we were able to ski
using a 100 lb adult spotter. Unfortunately I don't have a prop size but your prop size should be near the base of the blades.
if you had the prop size and a lightly loaded gps speed we could tell how your setup is working. I believe a 25 is rated for about
31 mph.
