Is this drive a true OMC or does it share the same parts as a volvo SX?

Attached are some pictures from what I believe is a 1995 Cobra drive on a 1995 5.8L. I understand that OMC is no longer in business and parts can be a little difficult to find. Should I cut loose of this boat and look for something else or is it just a little more difficult to find parts. I would also like to know if the outdrive is the same as the Volvo and if parts are swappable. I am also looking for the screws to drain the outdrive and I am not seeing them even though I have seen pictures on where they should be so maybe someone can tell me the exact drive I have based off the numbers I provided in the original post. Last question is on the drive filling procedures. I have drained out of the bottom and based on what I have read is that you must fill from the middle hole and check at the top dipstick. What I am not sure of is if I have the center fill hole as it does not appear so and if I do I want to verify the location as I don't want to remove a screw that should not be removed. With both sets of screws not appearing as I have read the should I am questioning the exact drive that is on the boat.

Thanks for the help!

That makes sense as I did not see a middle fill hole and I will check the tag to see what it says. Are there drain screws to drain the drive or do I have to pull the drive? I have already pulled the hoses and opened the block drains and filled back with RV antifreeze until all water was out and antifreeze came out each drain. After I got all of them closed up I filled just a bit more and I have it now coming out the exhaust. I don't have an alignment tool yet so I was a bit hesitant to pull the drive but certainly can do so if that is what needs to be done to ensure it does not freeze. Worst case I can leave it off until I get the alignment tool and then put it back on.

Thanks for the help!

you definitely have a Cobra SX essential a Volvo SX. I have the exact same drive and asked the same question. The hump on the top is a dead give away.
