Guesstimate My Range

[Airslot]

I estimated "useable gallons" because your pickup tube ain't gonna get those last 4-6 gallons out of the tank.

I would estimate 2 MPG on that 2000 Johnson. I have gotten anywhere from 1.9(rare) to 2.2(avg) MPG with my setup, so I base all my range off of 2 MPG to be safe.

12 GPH at 4000 RPM's is a safe fuel burn number for that 150 JOHNNY-RUDE you have if your propped out right. 9-13 GPH seems to be the range that most see with them. The 175 seems to get the same fuel burn numbers as well at cruise, but only slightly higher at WOT. The 200/225's actually were pretty close to the 150/175's on fuel burn at cruise.

Yep Thats what I am getting with my 225 hp, 2.5 just like my 175 was getting.

You can always carry a spare 6 gal. tank along for insurance.
