Just thought I'd ask the guys that probably run this type of water. The two pics are of the river I run here in KY. I'm looking real hard at a 1652 or 1752 jon with a 60/40 jet for this river, but I'm not sure if I need a tunnel. There are several riffles I need to cross and with my current boat (Seaark rivited 1448 with 25 Merc 2-stoke) I must get out and drag the boat. Will a non-tunnel jon with the 60/40 do, or do you guys think I need a jet tunnel. This is the worst riffle that I have to cross.
