Jabsco raw water pump

[Chrisc]

Bit of a senior moment going on here....
I removed my water pump">raw water pump for a rebuild, and I can't remember which way back it goes. The inlet/outlet are vertical when installed, and it can go either 'A' up, or 'B' up. The pump rotates clockwise and there is no indication on it as to water flow direction.
From my artwork, which outlet is suction, which is delivery?

Thanks

The pump can flow either direction. But the "A" side should be towards the thruhull fitting according to your drawing.

Great! Thank you.

According to your drawing A is the suction side and B is the discharge side.

Attach the hose from the seacock to port A and the hose to the engine to port B.

Go here and read how the flexible impeller pump works. There is even a drawing of a clockwise rotating pump like yours.
