OMC 225 307 sea water pump

[jwzlmartin]

I have what appears to be a hard to find sea pump. It is spraying water around the belt shaft. Any help locating parts or other matching bearinds or seals would be great.

they aren't real common...I'd say most likely an old sherwood pump.

What's the OD on the V-belt pulley?

Can you measure the hose sizes - I'm thinking one is 1" and the other is 1.25" (measuring the hose nipples on the pump, below the barb, is probably the most accurate)??
