    It should burn .75lbs of fuel per hour per 10hp (per Brett ;) ):

    40hp * .75lbs/hp = 30lbs / 6.2lbs/gal = 4.8gal/hour

    Now with my Tohatsu 40TLDI the book says 4gal/hour.

    Sounds like 5 GPH to me

    So to run "all Day" we are talking 40 Gallons of fuel ... Interesting ...

    What does that BEAST Weigh ?

    Like 275 or so ...
