What is the difference between standard alpha and the ss?

SS is 3" shorter then a stock alpha. SS uses a shorter upper case and uses a outboard CLE lower gearcase.

5 mph on a 22 pachanga

2.5 inches shorter

The upper case is not shorter. It's a standard dimension Gen 1 Alpha. I've never heard it confirmed they had HD upper gears from Merc but the parts breakdown I have for the drive lists the HD gear part numbers. The lower case is 2.5" shorter than a standard Gen 1 and has a crecent shape w built in nosecone. The cone is not as good as an Hydromotive design but gets the job done. The vertical driveshaft is also shorter and the water pump setup is a little different. It also has a low water pickup due to its shorter length.

It's the same as adding an Imco shorty lower to a Bravo.

It DOES have a shorter upper, with no cast in cavatation plate like a standard alpha. It does have HD gears. I have one, and have had a few before the one I have now.

I know the upper has no cavitation plate. It looks just like the older R/MR upper cases. How much shorter is the upper than a stock Gen 1? Merc states the SS was 2.5" shorter than a Gen 1 Alpha. The lower case is that 2.5". If the upper was shorter also, the drive would be shorter than the 2.5" Merc stated?
