1981 Motor Boating Magazine v20 with Merc 200hp

[THEFERMANATOR]

My 81 150 is the most fuel efficient engine I EVER ran in a large outboard. It was on a bass boat, but I could run for HOURS on a 14 gallon tank. Running along at 3600 or so it only burned 4-5 GPH which was a FAR CRY from my 2.5L XRI 150 I had on my flats boat that burned 11-12 GPH running the same speeds at teh same RPM's with the same pitch prop.

I have an 81 2.4 200 merc on my boat now and love the thing, it replaced an 88 175 johnson. The difference in fuel economy is night and day, the 2.4 merc wins hands down

The 88 175 JOHNSON was a cross flow fuel HOG! The old OMC cross flow engines were as reliable as ANY outboard ever built, idled good, and had gobs of bottom end power, but they could drink fuel like NOBODIES business. Still can't believe MERCURY got rid of the 2.4L engine that had good power and GREAT economy for the 2.5L that drinked fuel in the same league as the OMC cross flow engines.

I didnt get into the numbers but by looking at my bank statement i bet im getting around double the MPG out of the merc

I've never checked fuel consumption for mpg on any of my boats......so I have no idea.

Counting
1972 or so 9.5 Evinrude......not bad on fuel !
1980's era 140 Mercury " tower of power. " Forgot
1990's 150 Evinrude carb'd looper.......had 2 of them, used a lot above 4,000 rpm
1990's 40 Mercury, good fuel economy.
2004 200 Evinrude DFI Bombardier.....seemed to use same amount as carb'd 150
2005 200 Evinrude Etec HO Bombardier......seems same fuel use as the 2004.
