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

[anthonysjo]

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!

The drive is the SX. Probably even says so on the tag on the drive.



They fill from the bottom, they don't have a middle fill hole like the Cobra.

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!

Or you can pull the drive and put it inside...:facepalm:

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.

Thanks everyone. I am new to OMC so I want to make sure I do things right.
