It ended up that the other prop wasn't the right one for my boat. I have an extra prop, but its exactly the same as what I already have.
So far she's worked great, but I NEED a jack plate. I have got to get this motor up some. Once on plane I ran her in about a foot of water. But getting her up from that foot of water.....not so much.
If I can remember I will take some shots of her on the water.
