No but I can tell you this.

Your most fuel efficiant point is when your throttle hits max spark
advance - but before the carbs open up. You can hear the intake "bark" as
the butterflies open.

I have seen several reviews on boats showing fuel use at certain
RPM'S. I just got a new Mercury 150 Sal****er Classic, and I am
looking for fuel use at different rpm settings. Does anyone have this
information?

Thanks,

Chris
