I think some of these had the engine oil cooler on the side of the engine not in the rear like the P/S cooler...

Had one two years ago at the shop. He had the same issue, did everything you did already. I suggested he change the pump itself, it looks perfect, but he did it anyway. problem disappeared. I really think the housing was wore "just enough".

Does anyone have a picture of the water hose that goes from the oil cooler into the transom? Want to get a visual before I go in and try to swap out - hose coming in today. Thanks

Here's a pic of the back side of the engine, you can see the PS cooler there, the hose runs from there to the transom mount, its a very tight spot, depends on how your boat is set up, I can get at it on my boat but I have to remove an access panel above the rear of the engine. In the second pic, it is behind and below the distributor....You can just see it in the last pic, this is from when I was installing reman heads on my old engine. Mine's a Cobra but the Volvo is very similar, the hose is the same. Volvo just copied many aspects of the OMC Cobra design in the Volvo SX.
