It's hard to beat an I/O for fuel milage unless you've got a 4 stroke outboard. On the bright side though them old YAMAHA's tend to run forever with virtually no maintence except for the shift rods(which is easily fixable).

I know 4 strokes get better economy than 2 strokes, but never having owned a large 2 stroke I wasn't sure of how great a difference to expect. Hearing that I'd get up to 8mpg had me going though!
The motor is on a 21' center console I just picked up. I'll run it on that boat and see what kind of mileage it gets. It will have to be an impressive ride in order to get me to swap my 3.7 I/O to an outboard though.
