Hi Tellie: I have a Spectra Catalina, probably a 2004 to 2006 vintage...I think, not sure. Here is what is happening...I start the system, after about 5 minutes, the pump noticeably slows down...you can hear it, to the point that it pretty much stops. There is an overflow outside the boat as normal, I switch it to "manual" no change. I have not as yet checked the voltage at the pump....it just started doing this. Our boat is in Antigua, the watermaker guy there says he has never encountered this before, to contact Spectra tech and see what they say....I thought maybe I should run this one by you first. There are 1400 hours on the system, I put in all new filters, even though the others were all good, just in case....to no avail. Any ideas? Thanks!
