        Purchased this pump as an exact replacement 18 months ago. It has always run hot and now shuts down after running for a couple hours. Since the pump is 6 months out of warrantee, I will be looking for a differ pump as a replacement

              This pump make runs extremelly hot. Called the mfg about this and they said I should run it in a bucket. Wasn't going to do that. Turns out at one point a thing called an ice cube was available. This is a plexiglass box that the pump used to circulate water around itself so it wouldn't fry itself.

              West Marine shouldn't be carrying this product.

                        Comments about Seawater Circulation Pumps:

                        Since the boat came with a Cal pump 1200, I assumed this was the right pump for the job and replaced it with same. As experienced by other reviewers, I have had to replace the pump every one to two years. West Marine has always honored the warranty and provided a replacement, but it requires an hour in a tight space to remove and replace the plumbing and electrical connections. If one happens to run just over the two year warranty, you get to pay for a new one. These pumps are quiet, but run very hot - too hot to touch. My guess is that they were designed to run submersed in water, as in a fountain. The extreme temperature changes seem to cause the stainless cover to separate from the brass base, causing the oil to leak out, create a mess, and leading to motor failure.

                          Comments about Seawater Circulation Pumps:

                          My aircon CAL Pump has been leaking oil since 2 years into service and finally, it trips due to overheat after 4years with total loss of oil. Simple solution, open the large allen grub screw infront of pump, pour in Luboil (same SAE 15W40 as for my diesel engine), re-orientate the cable entry to top facing and the pump is back in service. Was leaking oil through cable gland when gland was faced down. Great pump, no need to buy replacement.

                          I have replaced two MS-580s in two seasons. Each was used to run my 16K BTU Marine Air AC. While they appear rock-solid and are easy to install, both began leaking their dielectric fluid into my bilge half-way through the summer. While the company declares they have a thermal switch to prevent damage if the intake is clogged, it seems they do not shut off until they are already leaking. Unless you plan to only use these pumps a few months out of the year in crystal clear water, I highly recommend looking at another pump.

                                  I'm replacing my boat's original pump after ten years of using it heavily. It's very hot in AZ and we are on the boat every weekend, running the AC constantly. Since the last one gave ten years of hard service, I'm buying the same brand and model to replace it.
