Raw Water Pump and engine rotation

Had my raw water pump off over the winter. Went to put my raw water pump back on last night. I could not remember how the impeller case is assembled. It has a three hole pattern, so it has to be one of three ways. I know the hose on the bottom is the inlet side (mayb not?), so as the pump turns it has to draw water up and into the pump.

If I am looking at the front of my engine (the RWP is on the left), the engine rotates counter-clockwise (checked that by bumping starter). I found this one picture of some other guys motor. This is about the only way I can assemble my impeller case and actually get the hoses on. But, this seems TOTALLY wrong. The way it looks here, as the motor turns, the pump would be forcing water OUT the pickup hose.

So am I confused?

Guess I should have made some pics. but it seemed simple when I was taking it off. It was working great before I took it off.

Help!

Sorry... its an 87 SN, 351W motor, Sherwood pump. I think the pic was from an '89, but it looks just like mine.

I think I figured it out after I looked at closer at the impeller housing and looking at this picture from Sherwood. Mine will go back on just like the picture shown in my original post.





Now I just have to fix my stripped threads in the housing case and I will be good.

Thanks

Careful, in 89, they started with the gear reduction transmission and Left Hand rotation motors. So, even though yours is the same design, there is a good chance the rotation is different.
