Mercury 150 XR-6 MPG ?

I have a Mercury 150 XR-6 outboard on a Triton TR-186 What is your guess on miles per gallon? This is not fuel injection, its the standard carb.

I'd say about 2mpg

I'd say about 2mpg

Give or take a little.  I've got the fuel injected 150 and get between 2-3 on tourney days.  The rest of the time I run it pretty easy and can get around 4 (these are my best guesses of course).

6 to 8 on Kent Lake

Maybe 4 downhill. 

It would be tough to guess mpg. Its probably better off not knowing. Unless your planning on making a 40 mile run.... And then I still wouldnt trust a guess.

I had one on a Bass Cat years ago.  WOT it was about 2 mpg, at 4000 RPM it would get about 3 mpg.  With that small tank in the Bass Cat I didn't have very good range.  It was an older Pantera (1988) and I think it only had about a 20 gal tank.

I still run mine and about 2mpg at full thottle but I usually stay around 4000.
It is bulletproof and that makes up for a lot of gasoline.
