I have a 3.5 hp Tohatsu with a 1 litre tank. I've never systemically charted it, but I think I get about 1 to 2 hrs of use before having to re-fill. Of course, it depends on what you're pushing, in what conditions, and how fast you're going.
I carry a gallon (~2 litre) tank with me at all times, and can refill in pretty quickly. No cool down period needed (so far
). I certainly wouldn't want to try and refill using a 4-gallon jug. Way too heavy and awkward in a bouncing dingy.
