Well, I have a Honda 9.9 and have sailed nearly every weekend this spring/summer and several times during the week. I have used about 3 gallons. But I suppose that doesn't answer your question. I suspect that I have motored about 30+ miles. But, the better question would be at what speed? I have pushed the motor at different speeds from 3Kn to 6.3Kn. I would warn you, when I first pushed the motor at the high speed my auto bilge pump siphoned water INTO the cabin. I have since added a check valve (about $5 at West marine) and have not had that "experience" again.
PS, what is the abbreviation for Knots? Joe McCary Aeolus II West River, MD [EMAIL PROTECTED] On Behalf Of David Techlin Subject: catalina27-talk: storage and gas mileage Two questions: 2) What kind of gas mileage can I expect pushing my 27 with a 9.9 Merc 4 stroke ? Planning on a trip this summer, and know I will tick off the wind gods and have to do some powering.
