I finally got around to looking at the fresh water pump on our Catalina 30. It had completely stopped working but it had not been a high priority until recently. We are wanting to go out for more than a day sail now and it will be more than a convenience to have running water.
I did not have a multimeter with me to test the motor so I did the next best thing. I removed it and brought it home with me. The location of the pump is right next to the macerator pump beneath the couch or main berth. 
There is an access panel beneath the cushions so it was not too difficult to get to. Removing the pump was a matter of making sure that the power was shutoff at the panel, disconnecting the two wires that connect to it, and removing the three screw that secured it in place.
I never realized that there was a filter attached to the pump which is quite obvious after seeing the “gunk” covering the filter.
This is the pump removed.
After examining the inside of the pump it appears to be a lost cause. Upon opening the pump there was a burnt smell and the motor appears to be frozen. i don’t know what else to examine so it appears that I will be replacing this with a new pump.
