I've been figuring maybe 1/2 gallon per hour, but haven't been able to find any good information. It would be good to know to get an idea of our motoring range.
Not really...I found the info on one of the Tohatsu websites. It showed the 9.8 4 stroke burning 1 gal per hour @5500 rpm. The 6hp 4 stroke burned 0.5 gal per hour at similar rpm. My motor is the 6hp and I have yet to burn a full tank in an entire summer-and we go a couple times a week. Bottom line is...they don't burn much gas.
