So i have a 1976 seaswirl ranger, in it right now is a mercuiser 140 181ci 4cyl.
It also has the mercuiser pre alfa sterndrive.I have been doing some reserch and noticed that the mercuiser 120 153ci 4cyl is pretty much the same thing. with less power. So heres my question does it matter if i use a 120 or a 140 and do they bolth bolt up the same to the mercuiser sterndrive??Im shure this question has been asked a hundred times but here it is again lol.
