Default Re: Fuel consumption

Summary; after replacing the plugs, thermostats, temperature sensors, cleaning the carbs and replacing the floats, needles and seats, I think I finally got the boat useable. It idles great, throttles up immediately and does everything you would expect an engine to do.
These numbers are still not perfect because we didn’t have time or decent weather to perform good tests. 20 knot winds with 30kt gusts and 8" chop.*These are short distance speeds (just enough to get leveled out).
Got a 14 x 19 ss prop at, 5000rpm-42mph-19.5gph, 3800rpm-30mph-10.5gph,1250rpm-5mph-2.5gph. Boat was ¾ full of fuel.
Next time it hits the water there are to be fishing poles in it.
