Good advice here. Step-by-step is the answer. The questions you initally asked (how far, how long, how much fuel) are things that YOU need to find out based on YOUR boat. I can tell you, f'rinstance, that I use 0.483 gallons of fuel per hour on my boat. How? I keep track of it, and have over 14 years now. That said, some of my colleagues with the same boat have differing results. Why? Same engine, different throttle settings, same boat different (bigger) engines.
One thing not yet discussed: you NEED to be a jack-of-all-trades. Mechanic, electrician, plumber, cook and chief bottle washer.
Learn about these systems and learn how to do it yourself.
For example, many folks take diesel classes, but I for one wouldn't waste my $$ on that if the engine they used wasn't the one, single, only engine that I had on MY boat. Bleeding is different for different engines, so are starters and solenoids, etc.
Learn about spares - what you need, what you can carry, what's necessary and what's not.
Dream on, and read - a LOT!
All the best.
