Author Topic:   Marine head operation on 21WA

Have new boat no owners manual.
Would like to make sure head operates correctly before I decide to discourage its regular use.
The toilet (ceramic under starboard berth) hand pump and thru hull appear OK. There is a small two position valve that enables flush/empty of the bowl. Pump flushes and drains bowl.
What happens next? Under the helm station is a holding tank and there is a waste fitting on the starboard gunwale. My guess is that the key switch near the head activates the macerator. This key turns but nothing happens. The boat power is on. Is there a fuse for the macerator? Was there a separate manual for the marine head? Any suggestions would be appreciated.

Your 21 Walkaround has a Raritan Compact II marine toilet. In your forward bilge sump (located in the floor of the cabin) are two thru-hull fittings/valves with open/close handles. One is the intake for the toilet and the other is for overboard discharge. The overboard discharge valve should always be closed, and the intake should be open.

To operate the toilet, move the shutoff handle to the horizontal (open) position (which allows seawater to enter the toilet bowl thru the rim) and pump a few times to rinse the bowl. When finished, pump a few more times to discharge the waste and then move the shutoff handle to the vertical (closed) position and pump until the bowl is empty. Leave the shutoff handle in the closed (vertical) position when running the boat to prevent seawater from being forced into the toilet.

The key switch near the toilet turns on the macerator pump for overboard discharge. You should hear the pump running when this switch is held on, if not, the circuit breaker (behind the hinged helm station) may be tripped or the pump may be bad. Mine quit working after several years and I got a rebuild kit from Jabsco.

The waste fitting on the starboard gunnel is for pumping out the holding tank.

I have the original Raritan owners manual (4 pages) and will scan and email you a copy.

Thank you very much for you concise instructions.
You answered the main questions - Does the head have overboard discharge? Where does the macerator lead to? I only found one thru-hull in the sump in the companion way floor so I was beginning to think the system was Type III with no overboard discharge. I'll have to look further for the discharge thru-hill. The marina launched the boat before I could get around to figuring out all the thru-hulls. I don't yet have a trailer (thats another issue) I checked the circuit breaker on the panel and it is set and there is power to the Brown/blue wire but the macerator does not work.
I have located a place to get an owners manual. That will be a big help generally but I don't think it will tell me how to get the holding tank out to replace the macerator pump.
How did you do it? There is a wire guide/flange on the floor forward of the helm panel that might be right over the tank. Is the pump inside the tank? I have only had the boat a week and am not looking forward to cutting panels away for access. Is the wood interior joiner work glued and screwed or just screwed?
It is the most beautiful walkaround I have ever seen. Before I found this boat, I kept telling myself there has to be something different than Grady White overnighters (Plentyful good solid boats but with a different look). I was also looking at Parkers, Easterns, Roth Bilts, and other Maine lobster type boats but they are all way over my budget. My whaler friends and I go down in the evenings and just sit on the gunwales and admire it. Last night I realized that there is ice chest under the port cockpit seat. I wish there were some drawers? Maybe I haven't found them yet.
Good boating - watch out for hurricanes

Forgot to thank you for you offer to scan and email the Raritan literature.

Yep, there are two thru-hull valves in the forward sump.
BTW hull number is BWCEA022E191. Could this be the 22nd hull?

If your macerator pump is mounted in the same position as mine I think you might find it to the left and aft about 12" of the holding tank (if your facing the holding tank from the inside the cabin). Additionally you should be able to locate the pump by pointing a flashlight up along the starboard side from within the cockpit. I haven't found an easy way to access the pump for service.


i will be sending owners manual waste system schematic to your email address.

Thanks for the scan. It does give me the the overall layout.

As Henry pointed out, the macerator pump is located to starboard just right of the helm station when standing at the helm. If you remove the white vinyl "door panel" you will see it, but probably will not be able to actually get to it.

I ordered a hatch cover from Whaler, like the one to the rear of the helm seat, and cut it in below the "door panel" to give access to the pump. It also opened up a ton of extra storage space.

The ice chest you are referring to under the port seat is a live well, plumbed from the washdown pump, unless you don't have the washdown option. I use mine more for storage than anything, but it also makes a great cooler. Is there a drain in the center of the floor in your "ice chest"?

Thanks for the great scans. They are really helpful particularly if I ever have to get a spare part.
I can't yet visualize the "white vinyl door panel" that you decribe that allows access to the macerator. Is this in the area that is exposed when you swing the helm/wiring panel aft?
Actually I was in the Raritan plant in Ft Lauderdale about three weeks ago. I was helping my friend move a boat. We broke the selector valve stem on a Raritan head. My buddy said "just about any product related to boats in the USA has an office in Lauderdale." Sure enough it was their main office. We walked in the door. I held up the valve. The nice lady recited the part number from all the way across the room. Actually we had the "A" model since it had "O" rings installed. Done and done. A noteworthy occurance when something breaks on a boat and you just go and get a new one. It hardly ever happens like that.
Yes there is a drain in the "well/ice chest" under the port seat. I found someone willing to sell me a Walkaround owners manual. Maybe that will help me figure some things out. At least I'll get the terminology.
The 2 long wells still puzzle me. They fill up with rain water. Is the walkaround topside attached to another production hull. The after part of the wells goes under the sole and over flows into the main bilge right next to the battery and the VRO tank. There is no way to drain them except at speed. I understand that the longer models had pumps on these wells. No washdown pump onboard. Everybody likes the cuddy light strip.
Thanks again.
I really like the idea of the Standard Gas flow meter.

I'll take some photos of the "door panels" and email them to you.

I have misplaced my owners manual, but as I recall it really wasn't very helpful and basically (very basically)covered the 21' thru the 27' models.

The two fishboxes in the cockpit are one of the few poorly designed features on the 21. They should have been designed with a lip so water doesn't run into them. I finally installed bilge pumps in both of them, wired to a single switch, so they can be drained while at rest. Yes, the larger models had icing grates and macerator pumps installed.

If you have a washdown pump it will be installed in the rear bilge sump on the starboard wall.

I finally get it!
White vinyl door is on the after side of the starboard seat pedestal. You cut an access hole in the floor of the lockable storage compartment under the seat??? Brilliant. Tied up the Gimcrack for the night. Its blowing but we're not expecting much. There is a plugged unused thru-hull in the aft sump (port side). Would that be for a wash down pump? Does Backlash have two batteries?

No, you don't get it yet. The photos I emailed you tonight should explain everything.

The plugged thru-hull portside in the sump is the sump drain - it should be removed when storing the boat outside for the winter to allow the sump to drain.

Yes, I have 2 batteries - one under each rear jump seat.

The photos that you emailed to me explain everything. Just as you said. You have done a lot of cool stuff. I like the cup holder above the instrument panel. Right now the cockpit has no place to put anything. Thats going to be my winter project. The boat has a Raytheon Loran EchoNav which I want to replace with something a tad more modern.
Thanks again and again
