Fuel consumption
I know that running WOT kicks up my fuel usage. But how much compared to backing it off a bit and dropping a few MPH? Someone recently told me that running my Yamaha 150 2 stroke WOT almost doubles the fuel consumption. Range is important just now because the albacore are 30-40 miles offshore.

Re: Fuel consumption
Not certain on your YAMMIE, but my 140 EVINRUDE looper burns around 7-9 GPH from 3600-4400(actually burns more from 3200-3600), and burns around 13-16GPH top end depending on which prop I run. These numbers are verified via a calibrated floscan guage. Most 2-stroke outboards I've run start sucking fuel above around 4200 though.

Re: Fuel consumption
I've been doing MPG averages on every trip. My top speed is 42 MPH and very seldom have an oportunity to floor it. Without a flowscan for accuracy, my best averages are at 26-28 mph cruise and I get 2.4 MPG with my 99, 150 Johnson looper.

Re: Fuel consumption
any one tried a Faria Fuel Management Gauge(simular to the flow scan), I can get a good deal on a new one, but its not a deal if they aren't any good

Re: Fuel consumption
I do a 20 mile trip every day, with tons of moving around for new drifts and different areas.
I use 17 to 19 gal a day on my 1987 175 hp Evinrude. Doing about 25 mph as the sound is always choppy here.

Re: Fuel consumption
Yeah, Tuna...no doubt WOT's gonna consume MUCH more gas than lower RPMS...and it should be run there from time to time to keep it runnin' good, but in normal operation, yer gonna get best fuel economy at a reasonable speed somewhere around 3/4 throttle or a little better ... my max PRM is 6,000 and even the Honda sucks it down pretty good there, but cruisin' between 4,000 and 4,400 RPMs she do REEL nice on gas and gets around at 30 mph ;) ...

Re: Fuel consumption
Thanks guys. Hopefully the mechanic will get the Yammie running again tonight. He thinks it's the stator that went out on the first splash last weekend. If it's ready for the weekend we'll make a tuna run on Saturday (they were 34 miles offshore yesterday). We have 2-3 or 3 other boats that'll caravan out together. The ocean is predicted to be pretty flat but I'll keep the RPM's in the suggested range and track my mileage. I'll let you know how it turns out.

Re: Fuel consumption
Just remember the old adage for fuel usage...1/3 out, 1/3 in, 1/3 reserve...ask yerself, "Will she do the 34 miles out on 20 gals?...well, WILL she??" ...
