There are a few ways to identify alpha One Generation 1 or generation 2 which drive you need. If the boat is a 1973 to 1990, you will most likely need a alpha One Generation 1. If it is 1991 to present, you will most likely need a alpha One Generation 2 drive. If you have a 1990-1992 boat you should make sure to I.D. it correctly before ordering. Also,if you do not know the history of the boat, it is possible that someone changed the model.stern drive at some point. They are not interchangeable without changing the gimbal housing assembly. The first thing to look at is the way the trim cylinders are attached to the drive. The SE106 drive
uses rubber bushings, large washers and nuts to hold them on. The SE116 drive uses small plastic bushings, small washers and e-clips to hold them on.
The next thing to look at is the water pump housing . The alpha One Generation 1 drive uses a plastic water pump housing . The alpha One Generation 2 uses a stainless steel housing. Also worth noting is the shift lever. alpha One Generation 1 drive does not have the “L” shaped lever whereas the alpha One Generation 2 drive does . You will also notice that the alpha One Generation 1 upper and lower are held together with studs and nuts and the alpha One Generation 2  is held together with bolts and nuts.
