How do you tell what kind of merc outdrive a boat has? This is for an '03 w/ 4.3MPI motor.
EDIT: There's alpha and bravo and different revisions as well, I think. This is a little confusing.
This is a boat I'm looking at purchasing. I'm looking for a general rule of thumb for outdrives id? What do you look for to tell them apart? Is there a rule that say if you motor is so big you will need x drive?
