Depending how damaged it is and how quickly you need it repaired- I bent over the ends of two of the fins on my prop a week ago and temporarily fixed it myself (for now as I didn’t have a spare). Can’t miss any boat days!

I made a template from a good fin and using a large adjustable wrench I careful bent the fins back until they matched up with the template. Took it out this weekend and it worked perfect...no vibrations.

I did order a new prop and will get the damaged one professionally repaired/balanced.
