Best way to do this is to run it with the present prop as it would be loaded.
get us the year of the motor, prop size,(on the barrel or under the prop nut)the max rpm and speed.A tiny tach is reasonable,easy to install.a gps for speed if possible.
For its health and efficiency the motor needs to be able to run within it max rated rpm at wot(wide open throttle).The good news is a Basic 1652 should get up fairly well compared to smaller boats when loaded.

You might need a spare prop you could get it rehubbed and test run it.

I've done a little looking around, I think a 12" is a good start assuming carefully balanced front to rear. If your crew aren't too beefy.
