Trolling Motor Props.
 

I have 72lb thrust Greatwhite trolling motor. It has a 3 blade prop on it. My question is what is the best prop to use. I mainly freshwater fish so therefore I'm in grass a lot. It's on a 1648 alweld boat that's kinda on the heavy side. I see they a metal prop among several different other ones. Just wondering if anybody on here has tried any of the different props they offer.

Got an extra 3 blade hanging around if you want it.

you must have givin up on that merc and be goin to use your tm to get you to the fishin spots, do you need a jackplate to:D
