I have a Mercruiser motor that says 140 on the valve cover serial # 3247087
I have found 140 - (GM 181CID 3.0L I4) 3332138 THRU 5157668
The pre Alpha sterndrive is serial # 3250402
I have searched for info but cant find anything for these specific numbers or a number range they fit in
I just want to know what they are specifically and the ratio for the sterndrive
I believe the boat is a 1972 SeaSwirl Cuddy
