I think bottom paint impacts MPG.

MY 270SD with Honda 225's gets 2.2 to 2.4 MPG at cruise (3800 +/-) close to 30 MPH.

My boat does not have bottom paint.

My 2000 266 SC with twin 2001 Honda 130's new blocks and heads in 08 and 09 replaced by Honda under Service bulletin.Over the last 9 years Regular Fish and dive trips Gulf of Mexico 150 miles plus per run...loaded with 8 tanks, 4 divers, baitwell full, 200 gal fuel my average is 1.6 MPG....we do very little if any trolling...Have seen 1.8 mpg on shorter lighter trips without tanks ....my normal cruise speed is 25-28 mph at 4500 - 4800 rpm. Props are Honda 13 1/4 X 16 SST. If you use 1.5 mpg as a standard for calculating you should be fine.

Covered about 130 miles on the last fishing trip. Left with 3 guys, full gas tanks, full fresh water, ice and gear. Went out (50 miles?) at 3,800 - 4,300 rpm, got some bait, filled the livewell, slow trolled, changed locations at 9-10 knot fast troll, more slow trolling, more fast trolling, did some jigging, and ran home. Was out maybe 13 hours and I think I got about 1.2 mpg

1.2, I really like the idea of the 29DC, but looks like the extra size really puts a hit on the gas mileage. Doesn't look real heavy or like you were running too fast either.

If I stay at or below 3500 rpm the mpg is better. But, 50 miles is long way to go at 3,500 when you want to get the morning bite. We were also getting some good fish jigging at the end of the day and stayed longer - so ran back above 4,000 rpm. I do think the 29DC is heavy, no complaints though - the hull size and weight translates to a nice ride.

That's what I ended up with, I think that the 21's would actually be just a little faster and effecient, but this way I can load her up for overnight trips and not work the motors too hard. With a normal full load she tops out at 6150 rpm and 45mph. At our normal cruise of 4750 we get 35 mph and 16gph. Not bad, and a normal burn for a 14 hour day going 100 miles out is now 100 gals instead of 140 with the 2 strokes.

What kind of speeds are you talking about at 3500 and 4000 rpm? I have even longer runs at 100 miles each way and don't want to spend all day driving.

if I remember correctly 3500 rpm is abt 25 mph, 4000 rpm is abt 30, 4500 rpm is abt 35. The 290 is a great ride at 5000 rpm (40 mph and 1.1 mpg ?) if the waves are 1.5 or less. The hull can slam with the "right" 2-3' waves so I take what I can get without a lot of pounding. World Cat says WOT is around 50 mph and I have tried it. The hulls are rounded in the aft and I don't think the 290 tracks as well when riding mainly on the rounded hulls. If you want to go out 100 miles I guess 40-45 is a realistic top speed if the water is suitable BUT at that speed you might get 1.1 mpg and your range drops to 275 miles. Doable but not much safety factor.

My 2008 290DC gets a consistent 1.5 MPG at 4150 and 30-31 MPH with 4 passengers, gear, and full tanks of fuel and water. That's best cruise, at least for my boat. On a calm day with 1/2 fuel and wind at my back going downhill I'll sometimes see 1.6. Although many advise trimming the engines out and keeping as much weight in the back as possible I've personally found this doesn't make a significant difference, at least not in typical Gulf of Mexico 2-3 ft chop. Actually, trimming the bow down a bit makes the ride more comfortable and actually runs .5 to 1 MPH faster than full trim (same throttle). WOT runs about 45 MPH at 1.0 MPG.

World Cat's "prop tests" are a bit optimistic in terms of mileage and WOT. Those results may be achievable with an empty boat and the hard top removed but you won't see them in day to day use. That said, considering the space and comfort on the 290DC, it still gets reasonable mileage.
