Spare Prop Needed

[Glock]

I recently bought a mastercraft X7 from a fellow baller. I now use it on lakes and rivers, not private water, which have lots of sticks, logs, trees, and literally anything else you can imagine floating in it. I mostly stay in our protected course but do like to get out and free ski a bit. That said, I think I would like to have a spare prop as I just know I am going to hit something eventually. Hopefully a spare prop might save a weekend. Anyone have anything that will fit a 197 or x7. Needs to be splinned and left hand turn. I have 1:1 tranny. Acme said I should go to a 3 blade 13X12 with .08 cup. If I buy new I may go with that. But I really don't want to spend the $ right now. Anyone have anything they want to sell me?
