Major QSC engine work

Those aftercoolers are the new style MOTO ones, yes?

I have the Seaboard fresh water flush fitting on my Groco strainer, with a quick-connect fitting. It's basically a full-port fitting that allows for full flow. The end mounted on the cap seals when the hose is removed as a backup to the handle shut-off.

On the oil drip, I think the pump for the QSC is gear driven vs. pulley driven. Off-hand I can't think of why oil would be dripping from a gasket on the water side - there shouldn't be oil on the water side. But maybe if there was a seal on gear side that was bad that might cause it. This is a pic of the water pump - maybe a gasket on the back side of the black flange?

I am noticing oil coming from my starboard engine raw water pump as well. First it was a couple of drops, now seems more. I am going to check the mounting flange for tightness, but I am fearing the worst. Does anyone have a part number for the pump, both Cummins and Sherwood, and what I might be expecting to pay should I need to replace it. Thanks
