This is probably talked about already, but I would like to know if there is a conversion from an aluminum prop to stainless.

These are my current numbers :

1991 Outrage 19
1992 Johnson 120hp ( 120 comp in all 4 cyl )

Current Prop - Michigan Wheel 13.25 x 17 Aluminum 763463

Max Throttle 5400 rpm
GPS speed 38 Miles/hr trimmed up with 1 person.

Note that size and pitch are not "universal" across brands. Aluminum and Stainless sizes are not interchangeable either.

I went to Michigan Wheel's website and searched based on your motor. They suggested their Ballistic 13.625 x 15 and Apollo 13.375 x 15

cf: https://www.miwheel.com/outboard-prop...-analysis/

If you want a different brand, the size will be very different.
