Funny to see such an old post of mine. The Jabsco mascerator I referenced did eventually go. I too would have described it as whining, but it was also having difficulty priming itself. At first, it wasn't bad enough that I was convinced it was taking too long to prime. Eventually, it was obvious.

I swapped it out with a Shurflo. The first time I hit the switch, prime was instantaneous and pumping was strong.

It's a crappy job. Mine, as I mentioned above, is buried deep too.

Re: The Jabsco Macerator... a ticking bomb of nastyness

FWIW, after replacing a Jabsco macerator twice over the years in my sailboat, I switched to Shurflo with the understanding that it has a longer run-dry time. That was several years ago. So far, so good.

I also use a Jabsco macerator in my powerboat to pump out the fish boxes and have had to replace it about every 5 years when it started blowing fuses or refused to run. I attribute that to the run-dry issue, as the pump has to self-prime for several seconds before pulling water through. I had been stuck with Jabsco replacements because I could not remove the hoses from the pump bell and therefore had a compatibility issue with replacing just the motor/pump and attaching it to the original 1990 bell.

You can understand why I am not a fan of Jabsco macerators.

Just curious, are you waiting for it to fail or you know it has failed?
Keep us posted on the replacement work - I may soon be facing the same pleasure....

The thing is held together by 4 screws that corrode... not sure if it's the salt, or electrolysis, but when they fail it comes apart and you get black water in the bilge.

I had to cut it out and jam a plug in the hose, while 1 1/2 inches of nastyness flowed into the bilge. (either get it over with all at once or let it slowly drain!)

I used the thru-hull as a sweetening ****... flooding the bilge and then pumping it out... until it was clean.

I'm still suffering from post-traumatic stress from the whole incident. I ordered a shurflo macerator today... but I'm not sure if I'll be able to face the horror of replacing those hoses (might as well while I'm in there) and installing the new macerator.

If you have a jabsco macerator on your boat... it's just a matter of time until it fails. It will probably be on a major holiday weekend or your birthday weekend (or both as in my case)
I have never had the slightest problem with my home built composting head and the whole system cost me less than you paid for the macerator.
Just sayin.

I've always wondered if dye marking the black water tank would become a trend or requirement. I've never seen it done, but have heard many. Is this becoming more common?
I can see that consenting to some dye to use a private mooring ball or dock might be a condition for use, but I have a hard time with the notion that a person would have to consent to dye put in their tank just to anchor in a bay.

I just recently dug deep enough under the Solon to even see where the macerator is located. It would be a bear to replace and it is one thing that I do not carry a spare. We're leaving next week for a cruise to Maine. Hope you didnt jinx us.

However, the discharge tube from the holding tank comes out the top with a fill tube to the bottom. Therefore, gravity can't dump it into the bilge. Nevertheless, a leak would be bad.

Mariner777 Yes marine sanitation (esp repair) has to be one of the worst parts of living aboard. I second the foolproof cedar bucket recommendation especially while underway at sea where it won't affect your neighbors... Porta potties can also be great alternatives to holding tank/ sewage repairs. I have all three systems on my boat.
