Waterpump issue?

[Ryank]

Has anyone seen a 225 looper johnson, with an alluminum waterpump housing? Everyone I have done is plastic with the ss liner. Now I have a 225 looper, 87 year, I pull the lower unit to replace the waterpump due to the not too impressive stream of water out the pee tube, and I come across a metal wp housing. with no liner inside of it. The teardrop slit in the front of it is going the opposite direction of all others. I replaced the entire assembly with a plastic housing, ss liner, pump, and now have no water pumping at all. Any ideas??? Do I have a unusual lower unit? It is a Counter rotater but that should not make any difference
