I am wondering if anyone can give me some good websites to search for used mud/surface drive/go-devil motors. I have a 1978 14ft extra wide/deep jon boat that i have re-painted and is in decent shape. Use it on river for ducks and catfish. Currently I have a '96 Merc long shaft 25 horse outboard on it. If I can afford it I would like to put a surfacedrive on and run it all year and sell the outboard. Any ideas or suggestions on where to look or if I should just keep the outboard? It runs good, hard to get to some of my duck spots though. Thanks in advance!!
