I have the 150HO and the 175pro xs rigged exact same boats are 5 mph - 7mph faster? What am I doing wrong. Same boats and same props. The Mercs keep killing me. I am getting 5200- 5300 rpms on a Mark Croxten raker 20 x 14.5 prop They get 60 and I am only getting 54-55.

what's the rpm limit on your engine?//maybe you need a smaller prop.

4800 - 5850 rpm operating range / 5500 - 5600 rpm ideal
