My glastron x-17 will do 35-37mph, at 5,000 feet elevation. What are you guys getting out of your mercruiser 3.0l 140hp?

Your speed is good. I have one in a 18 foot dixie fish and ski with a 3.0. 35 is what I get with the family loaded in moderate chop in a relatively warm lake with a 19 pitch. I feel that is pretty good too. I have been able to get to 42 on cold glass with just me and my son but I feel that is really on the upper end.

My 1988 18 foot open bow with a alpha one drive and a 17P prop will go 38-40 at 4600 RPM with close to 500 pounds of people in it.
