It'll be a great boat for small rivers and small lakes. You're paying for the motor. Those little jons are only $1k new.
One of my friends had a jon that was the same size. He put a plywood floor and small deck on the front of it, and ran an older Yamaha 20. I went out with him a couple of times on Taylorsville lake. Taylorsville lake is only about a half mile wide at best, but long and winding. The last time I went with him the wind started to blow, and little choppy 18" waves covered the lake. We had to slowly plod back to the ramp. Those small following waves would break over the transom, and had the bilge pimp working hard. I never went back out in that boat in anything other than a small rivers or lakes. It wasn't worth the risk. But that boat is great for small shallow bodies of water.
