So I ruined my prop the other day I hit a log and need a new prop and I dont want to purchase the wrong one. Is there a cheap universal one or something? I have a 1974 mercury 850 85 HP thunderboalt. Any advice would be great!

Your prop size should be under the prop nut or near the base of the blades.
Not trying to avoid helping but::
Trying to guess a prop size without your boat size,type dry weight and typical load and activities.
even then a guess would be based on the assumption a of a healthy boat and motor setup properly.
