At eight knots, according to the boat manufacturer and engine

That's probably about right for 8 kts but you will carbon up your
turbos and rings in no time at all if you run at that speed for long
durations. Fuel will look cheap compared to the overhaul.

If I were you, I'd be out on it today. Once you get the hang of
docking a twin engine boat it should be easy to take out by yourself,
and you can probably run all day on only $300 to $600 of fuel. What
the heck, it's only money big spender.
