Add a little more length and weight with 496s and I could tell you the burn numbers! =;   It would at least make you feel better when you see the numbers for the 360.    I'll tell you waste and non waste don't make much difference when you have a ton (literally) of fuel & 500lbs of water.

Hi Michael T

you have a great question. I think the basic answer is 1 mpg is your burn rate. I have silly way of calculating a quick fuel burn for outdrive single and twin engines. its all based on a simple ratio. for example... my boat is approx 13000lbs loaded. my total HP is 540hp. 540/13000 = .041ratio which seems to match 1 mpg at 28 mph. I think your 360 is around 18000lbs with I think 740hp equaling .041. note our ratio's match in this case. hence your burn should be nearly the same. if the ratio goes up your burn gets better since the boat is either lighter or has more hp. the inverse holds true as well. I have found that this math as odd as it seems is generally with in 10% accurate.... so your range should be .9 to 1.1 mpg.

MT, weight is usually a big factor as well.... people tend to carry more stuff on cruisers which directly affects consumption... I see some people carry enough goods to last six months for no reason other than to have it.... How you drive it makes a difference too... I know on the old website RBO some of the members had fuel flow meters, maybe one of these folks can give you the answer. I know my 320 costs about $50/hr to operate at planing speed. Roughly 9 gal burn rate at the rates we spend on fuel here... $1.50/L or $6 gal.
