Does the impeller in an Alpha gen 2 counter rotating drive spin the same direction as a standard rotation drive? By the marks on the inside of the housing, I think yes but I would like to verify this.
Someone that knows, please let me know. Thanks Phil.

Well, still looking for verification but, by looking at some things on the internet, it looks like the counter rotation is done after the water pumps vertical shaft and after it turns horizontal at the bottom of the drive. It makes since the engine is standard rotation.

Thanks Scott and Bondo. Didn't see your replies until after I responded to myself. It's still great to get some verification. Thanks, Phil
