I understand no two boats have the same engine performance or performance for that fact......Question....Two 36 Sedan Bridge boats with same cummins diesel engines (QSB 380)....One boat will max out at 2700 RPM and 22 knots (mine)......The other will Max out at 3000 RPM and 28 Knots.......My boat in did not get a lot of use in July so maybe growth may contribute to the problem......I have never opened the boat up in two years to 100% load and throttle....I did notice that at 90% throttle and 100% throttle read 2700 RPMs...Any thoughts
