I have an Alpha 1 Gen 2, 2003 model, 2.0 to 1 ratio on a mercruiser 135hp. Last season I punched a clean quarter size hole right through the housing. Managed to fix it with JB weld and used it for another 5 tanks of gas...pretty amazing, however I don't consider tis a long term fix!

A guy in my neighborhood has an SEI 116 (recent - I think a 2009).

Can anyone tell me if this will bolt onto my 2003 upper without a problem? I cannot use his upper because the ratio is 1.5

Any thoughts would be appreciated.

After a bit of research on the SEI site it looks like they sell a different product for the 2.0 ratio that I have. So my concern is that this lower off a 1.5 ratio drive will not work on my 2.0 ratio upper.

Any advice is appreciated - I only have Saturday to pull the trigger on this...

The lower unit on the 2.0 is a different ratio than the 1.5. I don't know if reproping would make up for it or not.
