Lower Unit with a different nose cone.

[Hydrodreams]

This lower unit came as an extra when I purchased my boat. Obviously the housing is trash. It's supposedly a 1.75 ratio and has a blowout ring of of some sort. The other abnormality to me would be the nose cone. It has three big holes and a rounded shape. I have only seen the pointy nose cones like Bob's. Anyone know where this duckbill cone would have come from? Is it any good, if you could/would take it off? Not sure what i am going to do with the unit yet. I will never use it, but I hate to see it sit around if it's of use to someone. I am sure it has a bunch of internal parts someone could definitely use.

No sir, not that I can see. I looked in there I assume the drain is easy to see? I have only had torqmasters through the years.
