OMC 307 225 sea water pump

This must be a very rare pump. Any suggestions on replacement? Very little room in front of crankshaft for a pump there. This has a belt driven pump located right in front of the fuel pump on the Chevy small block.

There is a raw water pump in the drive.----And that would be a " marine " circulation pump on the block.----Do not install an automotive one.

Here are some pictures that is the only thing I can see on pump. I am told it’s an original OMC and no parts are available for it. So I made the gaskets, cleaned it up, new, bearing and seal and put it back together. Something must be wrong with it.
