Jabsco 12v conversion

I have used one since they first became available. The first one failed within a season, the replacement, which had a few design tweaks, has been going strong for 15 years with no problems.
Advantages - so far, it's never blocked up, unlike its manual predecessor. The macerator really does pulverise everything. I've dismantled it twice to check it and found some hair wrapped around the macerator impeller, but that didn't stop it! Usual caveats about wet wipes and feminine sanitary products apply though, the macerator isn't that good!
Disadvantages - It's noisy. Really noisy, so you can't use it discreetly. This is a problem at night, if anyone has to use it during the 'wee' small hours (sorry!) then they have 2 choices - wait until the morning to pump it out, or wake everyone else up. I've also had to paint it as the outer shell went rusty after 5 years. I'm aware that it wouldn't be possible to empty it if the battery went flat, but that would then be the least of my problems.
Keep the manual pump as a spare, just in case, but otherwise highly recommended.
 
+1 for jabsco conversions. Never had a problem on my last and present boat. A lot easier for guests to understand, but my 9 year old won't use it because it scares her. My 12 year old won't use it because she thinks she's a teenager and that therefore the standard rules of politeness and basic hygiene no longer apply to her !!!

Note the manual pump has a flap valve attached to the base gasket, the conversion doesn't so if you keep the manual pump on board for emergency use make sure you keep the flap gasket with it. Chances are you will ever need to refit it.

Once you've used it no need to tell anyone within 5 boat lengths what you've been doing !

My motivation is the one of ease of use to guests who may not be overly familiar with the peculiarities of marine heads!



Sounds as if I have a plan, expenditure and a wiring job!

Thanks.

Tony.

I fitted one a while ago to the last sealine boat I had. Noisy......yes, especially at night and you could hear it outside but it was easy to use for guests and I never had any trouble with it. When you are wiring it up though you do need a good supply as it does draw a high current. I was lucky that I could use my bow thruster battery which was close to the head so reduced any voltage drop. They are expensive at first but a solid built unit.

Should have fixed a seat on the thruster tunnel and saved the space in the toilet.:rolleyes:
