I have a Champion River Jon 20', 42" wide mostly run a 20 Merc Jet, but have a 9.9 prop I use for trips on Buffalo and Crooked creek. I love the jet, but if was limited to 1 motor it would be a 9.9. When you are running hard and happen to suck up a bunch of leaves in a bend it resembles one of those dishes the kids use on the snow. Running the Little Red at low flow is a night mare, constantly choked up. After one trip always use my prop there. I have ran Shawnees and Supremes both good boats. Supreme nice finish, but I buy them to use, get that gel coat pretty skinned up. But nice.
