Jabsco rebuild-getting access

Toilet stopped working - probably the impeller broke and stuck because when I push the button to flush I hear a click and my panel shows 10+ amps being drawn but nothing else happens.

It is an electric raw water toilet and as far as I can tell a Jabsco 370* series(?).

I got a 37010 series rebuild kit and went down to the boat to install and have run into a problem...

The Jabsco youtube videos make it look so easy to just remove the macerator/pump and put in the replacement parts but getting to it in real life is much harder. I figured I need to take off the toilet bowl to get the bowl off of the base so I can access the black macerator pump. Three of the nuts seem to be coming off OK but the fourth (in green in my picture) spins the entire bolt when I turn the nut. I soaked it in wd-40 for an hour but it didn't help.

Do you think PB Blaster or Liquid Wrench would make a difference?

Should I just remove it by the base by removing the plastic covers and unbolting the two nuts that fasten it to the floor? (in red in my picture and behind cover #35 in the diagram)

In either case, am I at risk of having these bolts fall down into the bilge as soon as they are loosened?

Thanks!

Your photo is all too familiar to me, a trawler owner for 26 years. See those plastic "covers" in the base, four if I remember right. Pop them off and you should have access to the bolts that hold the entire head and motor structure to the base. Pull the toilet off and slide it out of the way and you should be able to pull the motor off to do the rebuild. In my opinion, it makes more sense to replace the motor. Re-builds are fine but no guarantee that the kits have all the parts that wear. New pumps are a few hundred dollars and avoid the hassle of rebuilding (dropped parts into the most inaccessible areas of the bilge)

You're correct that your toilet is a 37010...And from your description of the rusted bolts, a fairly old one. If the motor doesn't run when you push the flush button, a rebuild kit won't fix it. It's getting power, but that's all. I suspect a seized motor. You can download the owners manual from here: Jabsco 37010 owners manual If there's nothing in it that helps you diagnose the problem, give Jabsco tech support a call. Their toilet tech is Paul Campagna...his direct line is 978-282-5246

Thanks Hawkeye and Peggie.

Since the head is 16 years old I don't mind getting a new motor or even replacing it entirely. I'll try Hawkeye's suggestion and hopefully can remove the nuts that are behind those little plastic covers (#35 in diagram).



Do I need to take extra care to keep the bolts from falling into the bilge? It would be close to impossible to access that area.



Assuming marine toilet technology got better over the last 16 years, if I wanted to go with a complete new toilet, is there a no-brainer drop in replacement that might be quieter?

put 2 of the nuts from the other studs on top of the spinning stud then lock the top 2 nuts together. Hold the top nut in place with a wrench while loosening the bottom nut.

costs about double a new Jabsco 370xxx, the Raritain Marine Elegance is quieter.

You're gonna have to remove all the nuts to get the toilet out whether you just replace the motor and pump assembly with a new 37010 or another much higher quality.

Assuming marine toilet technology got better over the last 16 years, if I wanted to go with a complete new toilet, is there a no-brainer drop in replacement that might be quieter?

Marine toilet technology has improved quite a bit in the last 16 years, especially electric macerating toilets. Sea water toilets are noisier than toilets designed to use onboard pressurized fresh water, but they're all much quieter, less power and water hungry, and have much more efficient and robust pumps.

There are only two US toilet mfrs left who still build everything in the US--Groco, who has only two manual toilets, and Raritan Engineering who makes a complete line of manual and electric toilets along with a large selection of plumbing and sanitation equipment and accessories...all of which is always top rated. Everything Jabso sells in the US is now made in Mexico with materials and components sourced from China and other Asian countries.

The Raritan SeaEra Raritan SeaEra Promo Sheet was purposely designed to be a "plug & play" replacement for the Jabsco 37010...even the mounting bolt patterns are a match. Available in both sea water and fresh water version as either a complete toilet or a "conversion" (everything south of the bowl) Raritan SeaEra Conversion Promo Sheet

Or, you could upgrade to the very top of the line macerating electric toilet: the Raritan Marine Elegance--an all-china "throne" that's the quietest toilet on the planet! Raritan Marine_Elegance Promo.pdf

I'll be glad to answer any questions after you've had a chance look over the info.

Last year I installed two Marine Elegance electric heads. As boat jobs go, the installations were relatively easy. Very happy with the product. Plus, all of the operating parts are behind the bowl, hidden, and very accessible should anything go wrong.

I have the same toilets after sitting for about 3 months unused Mine did the exact same thing. Upon disassembly. I discovered that the impeller swelled width wise 60 thousands of an inch. I can't explain it but that's what happened a new impeller and things as good as new

FWIW, I was able to remove/replace our macerator/pump without dismantling the toilet. Not saying you should be able to do that, just can't tell from your pic...

I've also had mine off a few times without removing the bowl.
Also the back of the motor has a screw slot in the shaft and if you can get a stubby or right angle screwdriver in there you can try to rotate the motor.

^^^ This has worked several times for me after head wasn't used for a month. Eventually, I did change out the macerator.

That nut has a bolt head on the other side, likely can get to t by removing the head and flipping it over. I have similar very noisy Raritan head. I replaced the impeller last year, it is not all that easy. The bronze macerator is held to shaft by a set screw and mine corroded away. I may have had to drill it out.
Behind that is the rubber impeller. I also had a problem where the machine screws holding motor to to the plastic base, those metal threaded insert spun in the plastic. And of course the base cracked there too from corrosion buildup. That part is outrageously priced too. I manged to glue it, it is PVC plastic. And the rubber o-ring would not seal, thing leaked all the time, so used Permatex gasket maker.

Grease al metal bolts or use waterproof teflon pipe dope like Rectorseal T plus 2 teflon, otherwise they corrode together. The manufacturers know it and hope it does so you have to buy new hard parts or a whole new head. I honestly do not like the head I have, it has functional issues related to its small opening for waste that a modern home toilet does not have. The thing is just poorly made, IMO! It is what it is.

Defender has the Raritan SeaEra "conversion" for $389. You can upgrade to an Elegance for <$700 if you know where to shop. You'll like the SeaEra...you'll LOVE the Elegance.

Life is too short to endure using a piece of equipment several times every day that you hate.

What is the flush volume of say my Raritan head?

What I know now, and I paid like close to $400 or so thereabout for what I have, I honestly regret spending the money on it. It has not aged well. And friends do mention it being loud.

The seat paint is ok, but the hinge looks like its disintegrating, the plastic it is made from is developing many black looking surface cracking all over. Even old house toilets, you never see that. Just more evidence of a crappy head design that you pay way to much money for. I will take a picture! and post in a few days. I do not believe my situation is unique to me.

When you do, it'd maybe help to include exact brand/model info, and year installed...

That depends on which Raritan toilet you have. If it's a Crown Head (dinosaur Raritan introduced in the late '60s and is still in production)...depending on whether it's a "DeepDraft (DD") "Standard (ST)" or "Centrifugal Discharge (CD)" version, it draws 30-50amps/flush,needs 1-3 gals water/flush and makes enough noise to wake the dead...which sounds like what you have (most likely the CD version) and can be up to 20+ years old. Everything has a lifespan!! Raritan Crown Head Owners Manual

But your only complaint seems to be about the seat, not the toilet itself. Household toilet seats live in climate controlled conditions and don't have endure the abuse that marine toilets do. And if your bowl is the "household" size, you can replace the seat and lid at Home Depot.

The sea water version of the Raritan SeaEra draws 15 amps and is a LOT quieter, but not as quiet as the fresh water version, which draws only about 10 amps. Average flush from both versions is about 2 litres. Raritan SeaEra Promo Sheet

The Raritan Marine Elegance Raritan Marine_Elegance Promo.pdf is the top rated electric macerating toilet today. Designed to use pressurized flush water, it's the quietest toilet on the planet. Average flush is about 2 liters...however the optional "Smart Flush" panel offers 4 flush choices that can greatly reduce average flush water needed: bring in water and hold it ahead of use, dry flush, "light" flush and "full" flush.
