          Comments about March Seawater Circulation Pumps:

          It is a great pump but I was very let down that the unit did not even come with the fittings. Not even the cheap plastic ones. I was doing a one-for-one swap/upgrade and had to make a trip out the hardware store to get hose fittings. I expected a pump of this price range to come with fittings option that way I know going in there aren't any. Also the power cord length was way shorter than lower capacity pump. This caused another trip to the hardware store.

                  Direct replacement for Marine Air P500 pump. Very slightly larger but no problem fitting it in. Very quiet and free of vibration

                          I replaced the same pump that was installed in my sailboat in 1992. The current model has a different bolting pattern so watch out... otherwise a great pump, hoses hookups are the same as 18 yrs ago that was great cause I did not want to replace my hoses. If this will last another 18yrs, theyare fantastic.
