      we just got our TN-28 johnson 5HP running after a 25 year nap.
      rebuilt carb, new coils, condensers, SP wire but no new plugs.
      took it out on the river with a full tank and ran WOT for less than 1 hour.
      when I was a kid, I remember a tank full lasting at least a couple days
      my question: How long should a tank of gas last on a TN-28?

      thanks!

        Even at that, it’s pretty cheap fun!

          Fuel consumption rate has probably not changed, but pretty sure our memory has…

            The TNs tend to use a tank of gas per hour at WOT. But you can troll all day on one. I always keep twice as much fuel with me as I think it will take to get back home…
