I had an '02 225 OX66 on my 22' Whaler w/4 blade 17P Solas; 2-2.5 My '01 250 OX66 on my 23' SeaCraft w/bracket same prop gets about the same IF you behave
I've also had a 150 and 200 on other boats. They are one of the most reliable, dependable motors but like gas and oil. Keep the LP fuel pumps changed ~ 2yrs., HP pump tank/screen clean, and O2 sensor clean and they're great.
