Mercruiser Drive ID.

[windsors03cobra]

I was down at the launch today and was looking at the 2 drives on a Cigartette brand boat, they were red colored, massive and it looks like the bearing cap on the upper was bolted to the backside of the upper, instead of on the top side like most MerCruisers.
What kind of drive is this ? I did not see it on MerCruiser webby.

Drives on this boat look the same, only black.
