Helping a co-worker and have a prop question.
 

A lady that I work with use to work at Baja and race Baja boats a long time ago. She was cleaning out her garage and found a couple of props and I am not sure what they fit on or what they are worth. Any help would be appreciated. doesn't look like I am a loud to post any pictures yet.

prop 1 part # 48-77320-24. Looks like they are around $150 online, but what does it fit?
prop 2 part # 48-93591-24. Same as prop 1
prop 3 part # 48-89800-19. Seems to fit on my alpha, but it is bigger and lighter than the 19 that is currently on it (48-73980-19). Would there be any performance gains switching?

Did I post this in the wrong spot? I have never seen the 1st 2 prop on a boat before and she said they were expensive back in the day.

you need to post in the prop section..

Thank you!
