The Alpha One® drive is a staple in the sterndrive market. Time-tested by countless afternoons on the water, its fluid handling and efficient design have earned it a reputation for reliability.. MerCruiser drives are built with proprietary alloys and superior corrosion-preventive finishes developed specifically for marine applications..

The Alpha One 4.3-liter V-6 is the mating of either of the two MerCruiser 4.3-liter engines with Mercury Marine's Alpha One sterndrive power delivery system. The engine is available in two versions: the MPI and the TKS. Both are among the many MerCruiser engines compatible with the Alpha One sterndrive system.. I read about different model years and descriptions/sizes of mercruiser engines, 4.3, 260, 3.0, 350 magnum, etc. A lot say "With an Alpha One outdrive" Does the same outdrive fit all engines? If not, where would one look to find the correct match up?
