I've had 2 boats during my life. One was a 19' Trophy Center Console w/a 175HP, good to go a few miles offshore. The other was a 12' Jon boat that had a weak a$$ trolling motor that I got from a junk yard, with an almost dead tractor battery my neighbor gave me. (recharged it )
I've wound up having far more backyard Fish fry parties in the back yard from the Jon boat, and at a lot less expense!
