6010000CPMerCruiser Stern Drives
MerCruiser stern drives are the result of over 40 years of refining and reengineering the world’s best outdrives. And over 40 years spent as the unquestioned technology, performance and propulsion leader. MerCruiser stern drive technology is designed to maximize your experience–whether through ease of maintenance or trouble-free operation.
MerCruiser Alpha One Gen I Sterndrives
Mercruiser Alpha One Gen One stern drives were produced from 1984-1990. Improved gear design and bearing arrangements made the Alpha One drive stronger than its "R" Drive predecessor. These Mercruiser Alpha One's come in four different gear ratios: 1.5:1, 1.65:1, 1.84:1 and 1.98:1. The lower housings for all of the Alpha One outdrives use the same lower unit as the gearing is changed in the upper housing.
MerCruiser Alpha One Gen II Sterndrives
These are an updated design on the first Alpha Ones which were manufactured by Mercruiser from 1991-2003. The complete Mercruiser sterndrives come in five gear ratios: 1.47:1, 1.61:1, 1.81:1, 1.94:1 and 2.0:1. The 2.0:1 gear ratio was only available from 1998-2003 and also has a Mercruiser lower unit with a ratio of 2.0:1 as opposed to the standard 1.62:1.
