Any response to SH775AA vs ... BB? Are they all the same? I've also seen BA. Any difference in the suffixes?

I don't know the difference between the AA/BB/BA. I bought a good used BA because that's what the Forum suggested. I haven't installed it yet (still waiting on the wiring harness), but the mounting hole spacing appears to be the same as the OEM unit. If I had to take a guess what the difference is, I'd say it's probably the mounting bracket - which may vary for different applications.

I bought an AA, they are from a Sea-Doo jet ski. Exactly the same, mount and everything. I suspect it is just to identify who they made it for,
