When I had a Alpha Drive using an aluminum prop. I would replace it every-other year cause the small dings it would get in it. 30-40 bucks per-blade to repair vs 130 bucks to replace, keep the old one for spare. When I had three, I would sell the old one on ebay for 20-30 bucks.

A new prop with hub kit for a Merc application would cost a little more than what your dealer is charging.
But they're sending the prop out and performing some labor, so it sounds pretty normal.

It's a single aluminum prop, it wasn't clean, hit some low water in the NJ bays, scratched but not bad. Dealer explained that boat performance would decrease as the prop deteriorated and it sounded reasonable.
I would get a new one and install it. Then take old one and just touch up the rough parts with a file or Dremmel to smooth them out and sharpen the edges and then paint it up and have a decent spare. That way, if you kabong your prop, you could do a "field replacement" and get home on the cheap..... Just my opinion on what I would do.

There are also some very good high performance stainless steel props out there that would be worth considering if you want to squeeze out some more performance although many more deer. If you consider changing the prop type, it's best to test various models, if you have a dealer that lets you test props. Prop performance varies depending on the boat they're used on.
