I have a merc efi 250, so these numbers might not be much help. Also, do you have a top on the boat, that really drags them down some in speed/etc.

My best cruise/efficiency is 3800 rpm, 13.8 gph, 27 mph, 1.8-2.0 mpg. When setting up a boat, I always look for the best effiency cruise, top end dosen't mean much, as long as your getting all the rpms out of the motor.

I am swinging a tricked powertech 4 blade stainles. The 4 blades really seem to have some lift to help get the stern out of the water.
