I have had this pump on my 41 ft sailboat for over 15 years with no trouble at all. Now it just quit
but I believe something not intended was flushed and jammed the impellar and shorted out the motor.
I am very carefull about what goes through this pump but something must have slipped

Hope the new pump works as hard and long. Will post a comment when it is installed

Another over priced product designed to provide marginal performance for very limited time. THe 4 studs that hold it together invariably corrode. The impeller has a 6 month life expectancy. If you use it you "wear it out" if you dont then it loses its flexability. Nothing is more satisfying then the clean up job required when the studs corrode and the boat is sprayed with holding tank content. THey know about this problem. But refuse to upgrade or modify the design. Maybe they should do my next clean up job to find the motivation they need.

      Comments about Jabsco Macerator Pump:

      This pump is terrible. We are on the second pump in as many years. Only used as a light duty holding tank pumpout, using fresh water only. Both times the bolts have rotted thru and the macerator housing has fallen off, leaving quite a mess! The bolts should be separately sealed and the gaskets should NOT be paper. This seems like planned obsolescence on Jabsco's part, as I have not seen a design change in years. It will take quite a big change to convince me to replace with another Jabsco.

        Comments about Jabsco Macerator Pump:

        I agreed with all the negitive comments by the others boaters. I have purchased at least 4 of these over the last 20 years. Design has never been improved. The brass does always coridoe and break. You would think the company would do something about it! West Marine should at least inform customers to just how poor this product is!

        Comments about Macerator Pump:

        Had the boat yard install the macerator plus other items when I purchased my boat so it was installed professionally. The pump was used sparingly, yet it fails every time. It is most certainly NOT self priming nor is it rust resistant. We should be able to return it full for a full refund.

        Worst pump ever made

            Comments about Macerator Pump:

            I have gone through THREE of these pumps. All failed is a short amount of time. The bolts rusted through and each of the pumps has failed. They were purchased by someone else and unfortunately were not installed until after the warranty expired. I used them for a MSDD holding tank pumpout. And they are far too expensive for a simple 12 macerator pump.

            Comments about Macerator Pump:

            We use this pump to empty a 25 gallon holding tank about once a week. They consistently fail after about six months of service. The repair kit is $54 and on several occasions the brass studs have corroded through and broken when trying to install the repair kit. For the price of the parts you would think the pump would last longer.

            Own a 2008 Hunter sailboat that came new with this pump installed. Never used the pump and after 5 yrs it completely fell apart due to corroded bolts. Filled rhe bilge with sewage. Nice way to ruin a weekend on the boat.

                  This unit was installed stock by Hunter on the 2003 boat. Average usage guestimate is 25 gals weekly for 15 weeks per year. I got my money's worth after 10 years use.

                        I think I installed this about 18 months ago. I used it once last year when I cleaned out the fish box (Rig storage, fish go in cooler). I did my spring cleaning yesterday and it whirred quietly but did not pump. All lines are clear and shore water shoots through. I climbed in the guts of the boat and looked at the pump. This thing was a mass of rust! You would think for the purpose, it wouldn't rust so fast. Sheesh, and I only used it one time.... This thing is a piece of trash, don't waste your money. WM needs to do better with its selection of products.
