Outboard fuel burn rates

[MYS18]

anyone have fuel burn numbers on a 1996 Johnson 200 Oceanrunner?
Running it on a 1975 V20 center console. Fuel burn seems excessive, but nothing in the water, so I don't think I am leaking anywhere

Like BG carbed 2 stroke 200 would be about 20 GPH, That is wide open

U should be getting.between 2 to 3 mpg, but there are a lot of variables in this equation

You should also see a speed of close to or at 50MPH, depending on your load and the water conditions. What size prop and what pitch do you have on your engine?
