[QUOTE="spcamno, post: 360478, member: 13124"] Thanks Johny25 for your reply. After some research on the internet my motor is a 1989 not 90 and found info on iboats someone did a mod on a same model 89 by just open up the restriction plate. Can you tell me if it this the only thing difference between the 20 and 25? I remember read something about the cam on the throttle or flywheel to limit the rpm and the carb and manifold is bigger, is that true or only apply to the 30 or 35? Thanks again for your help.
