Spun prop on 1970 Mercury 200 20hp

[Mooselookmerc]

My basic question is can I fix my prop or should I look for another?
Some will know this is an 8 spline shaft, I have a 9" 2 blade Aluminum prop.
I loaned my alu single hull boat to the wrong person (ugh).
If I go the used route how common is buying a spun prop?
It was clear my wrong person tried to dig a trench in a shallow area. I only found out because it runs fine slow and reverse but any load it slips.

Rehubbing won't be much cheaper than a New Prop. Buying used, is always a gamble, because we all know Sellers NEVER fail to disclose faults.
