2 reviews for Medium Swamp Runner™ Kit (8-14hp)

    Best investment for my company ever!

  2. Ron P (verified owner)

    Hunted early teal with the new motor. We’ve got some pretty high water in the marsh, but that little 13hp motor sure impresses! I couldn’t believe the stuff we went through; saw grass, mud, sand, thick cattails. I had a try pretty hard to get it stuck. With three 180lb guys, and gear we got 14mph outta my light 14′ topper. I was only getting about 16mph with an outboard and the same load, but it wasn’t half as capable. Cant wait for the start of the regular season and Lake O!
