this would depend on many things, like the weight of the boat the motor is pushing, the speed, the sea state, current, wind, shape of the hull, etc.
good luck! |

Older outboards were not designed with efficiency in mind eiher, so it is most likely going to guzzle a bit.

On most family runabouts that motor would get in the 3-4 MPG area. A lightweight speedster might even nudge it to 5 or 6. A heavy party barge might get only 1 or 2. In general, most 2-stroke outboards will get about 10% of their horsepower in GALLONS per hour of fuel used. Therefore, your 90 should use about 9 gallons per hour at wide open throttle. Might use less than that if you throttle back to a good cruising speed - somewhere above a comfortable planing speed...
