They all have there pros and cons. I had a TMC electric for 3 years and it was perfect the entire time. We used to have a manual one on our boat as kids (20 years ago) and it was faultless apart from a service every once and a while.Select to expand quotecisco said..
Does everbody here actually know how to operate a marine dunny............??????????????????
You dump then you pump. You wipe then you pump, if necessary, a couple of times over.
I hazard a bet that I have unclogged and repaired more marine dunnys, both manual and electric, than anybody on this forum.
Dump, pump, wipe, pump i might have to use that one sometime. Unfortunately some non-boating visitors prefer to use it like a house toilet dump,wipe then try and pump the whole lot out at the end 
. Even if i tell them not too ):
After they leave im left with the messy job and i end up covered in piss and sh!t weilding my weapon of choice.. the humble yabby pump

Just one consideration to throw in here is the current draw from electric toilets. Mine is somewhere close to 15 amps when flushing. Not a problem if you have a good house bank and charging, but it's worth noting. With our setup, it's something I have to manage carefully on longer trips and it sometimes means having to motor for a while (to charge) when I'd rather be sailing...
Hi, when you do the maths an electric toilet may draw 15 amps, but for a very short period so the power used is very little in the scheme of things.
Yeah fair point Uncle Bob. It does add to my overall usage though when you add flushes to lights, fridge, phones, Ipads etc. When I'm parked up for an afternoon and a night with two on board, that can be a lot of flushes, add guests and it's doubled. Apart from the motor alternator, I have no other charging. I hope that'll improve a little when I finally get a chance to install the new solar panel that's been sitting here for two months

The new solar will truly change the cruising experience.
