OK, I was in Wally World yesterday, and they had two props that will fit my tm. One is the one like I have right now, minus the rough edges of course, and it was 25 bucks. Right beside it was another one that will fit all Motor Guides with the size hub like mine. The second prop is huge. It's about 3 to 4 inches longer than mine, and has quite a bit more curve to it. Will this thing hurt my motor. Cause if not, this thing should really generate a little more speed.
