Hi,  I am the proud owner of a BayRunner 220.   Purchased in 2004.   It is powered by a Mercury 150 XR6, 2-stroke, carbuerated.   I am running a 15 1/4 X 17P SS prop, and get 5500 rpm at WOT.    The rig performs well.   My question is:  I was expecting to get 3 mpg while at cruise rpm (between 3000 and 4000).   I am actually getting 1.75 - 2.0    I would like to be able to get 3 mpg, using existing motor.   I use the boat only for fishing and cover up to 60 miles on any given day in the inshore Gulf of Mexico.   Any suggestions on improving 'mpg' would be appreciated.
