hi all

i would like to know how much fuel a boat will need.
i know, this is not easy to answer, but a guess will be helpful.

think about a boat with 1000 Kg and a 10 jears old outboard-engine with
45 HP.
i will drive with full power, while gliding over a flat sea with 35 KM/h.

what do you think how much fuel i will need ?
