25' JH Outlaw with 300 Evinrude G2.

WOT = 2 MPG (50ish mph)
Normal cruise between 4500 rpm and 5000 rpm = 2.5 MPG
I have never gotten close to 3 MPG but I dont care.
I love this boat and the 2 stroke has grown on me (hope Im not jinxing it)

Just to tick some people off - cracks me up when all the Merc guys say they get/got 4-4.5 MPG. I had a merc 300 and it was 2.5...oh and it was ALWAYS in the shop.........

24’ Haynie Cat with a good bit of aluminum and t top on it, mid 50’s decently loaded with 250 SHO chipped to 330. Can get it to 60 not loaded and trimming her out. Right at 2 mpg as well but I don’t run it wide open for more than a minute or two. It likes 44 rpm at 43-45 mph and gets 3.5 or so there.

I back off just a bit and run it at 5000 doing 46-48mph. The motor sounds like it isn’t screaming as much at 5k

Haynie 24 VLS with a verado 350: 72mph @ 33gph ~2.2 mpg. @4000 RPM 47 MPH fuel burn is approximately 10 gph ~ 4.7 mpg give or take...even better at 3500..so not sure what cracks you up.

Man, 72mph is moving!! I bet it makes those runs to Baffin pretty quick. From the condo on the padre canal it’s a 45-55 minute run to the mouth of Baffin. I don’t know what my wot mpg is but my 115 ocean runner is a thirsty girl. Even at cruise I would say about 2-2.5 mpg

they can be set to gallons per hour, which is good for big yachts, or miles per gallon which is more geared towards small boats. :texasflag

2000 bluewave with a 140 Suzuki. Around 11gph at WOT doing about 42-45 depending on load. So 3.5 to 4 mpg.

Cruise at 30mph and I see like 7gph if I remember right. So in the mid 4s for miles to the gallon.

Need to swap my garmin to display MPG instead of GPH.

Haynie 25 Magnum tail dragger setup pushed by a 350 Verado. 23.5 FS @ 6250 = 70 to occasional 71.5 @ 2 mpg w/tournament load.
3400 rpm @ 37mph = 5.1mpg. Math checks out on trails vs gas pump.

How are you guys figuring your numbers?
David on my E-Tec G1, I had to install a NMEA 2000 to connect the GPS to the motor and it gives this reading. Otherwise fill your take completely, zero out your GPS trip, at end of day fill tank, divide the trip miles by gallons used.
