Trying to identify my lower units??

[jetski202]

Hi. I am trying to identify my lower units. These alpha ones have been repainted so no decals are on them anymore. All I see is a marking of “S-6-A” on the side of the housing. I’m going to be ordering spare parts for them and want to make sure I identify them properly. Any help is appreciated. Thanks.

They appear to be alpha one gen 2 drives

Given the left hand prop on the port drive it'd be safe to say that one is counter rotated while the stbd side would be standard rotation from the factory
