I have a 1985 Chaparral 178 and it has the mercuiser 140 3.0ltr.. when I got it the motor was popped.. I have found a mercruiser 120 which I now know is a 2.5ltr.. I know its a drop in hp.. which isn't a big deal since I never ran it with the 3.0 I wouldn't notice difference.. now here is my question.. Can I take my intake/exhaust off the 140 and mount it on the 120 so it matches up for the throttle cables and exhaust outlets.. now what about putting the 3.0ltr head on the 120.. would that increase any hp in the motor performance? I am an experienced mechanic in the car field.. but new to the boat motor thing.. and don't know a whole lot about the mercruiser motors.. any help is appreciated... thank you..
