I am not a dealer so I don't know this for sure but my guess is you will only find direct injection or four stroke being manufactured due to the epa issues. Promax was offered in a 2.5 from 150 to 225. In 3.0 it went up to 300. As far as what mounts and lowers were offered I have no clue. I know the xs motors were made in both 2.5 and 3.2 configurations. That's all I got.
