I think it is time for a new loo - I can get an identical Jabsco unit, but am concerned about the fixing bolts on the base.

Can you tell me - do these bolts screw into captive nuts or is a large degree of contortionism reuired to remove and re bolt them?

I suspect the whole replacement job is comparatively easy, but it would be nice to know in advance.

That would depend on the idea of those that build your boat.
Jabsco only provides the holes....

I've done it for two boats and both cases were wood-screws with a hex head. So I think you have a good chance removing and resetting them without a headache or backache.
 
It depends on who built the boat and how they built it.

I had the same problem when I came to fit new toilets in our current boat. I dutifully bought a little access hatch and cut the hole to fit it to allow access to underneath of the moulding that the toilet sits on as I thought I would be having to access nuts on the bottom of the bolts. I then discovered that the toilet was bolted down with stainless coach bolts into the substantial bit of ply built into the moulding. No need for the access hatch I had bought at all!

Bear in mind that in my experience the bolts on later (the latest?) Jabsco models don't line up with the holes for some of the earlier ones. Not a problem - but you need to fill and fare the old holes.

edit: I see that someone typed quicker than me!
 
You may not have to change the toilet completely. If the bowl and seat is in good condition, just replace the pump with the latest style. all the working "gubbins" are in the pump.

As already said the actual mounting in the boat will depend on the builder. Kind ones recognise that it might need replacing, others make it difficult to provide work for boat yards in the future.

Definitely just replace the pump. I struggled with a leaking pump, valve kits etc. till I rang Jabsco. They sent a new pump and it's been great ever since.

You might struggle to get one of the earlier pumps - and sometimes the base part that the pump screws onto cracks. Furthermore, the cost of the replacement pump is a healthy chunk of the cost of a whole new toilet! The latest pumps are much easier to service, and if the Jabsco toilet is an early one I would be all for changing the whole thing.
 
I've replace 2 on different boats ( changed small to regular size) first was botled to an aluminium plate bonded into layup and was a nightmare due to the holes caroding because of ss steel bolts used. I mounted loo on a ply base then used mastic and self tappers, avoiding the aluminium, to hold it Down. The second was a ply plate bonded into layup, far easier.
 
Mine was fixed with bolts and non-captive nuts and a bit hard to get to. A bit of gaffer tape over one side of a ring spanner caught the nut and helped to hold it in position whilst the bolt was threaded on to it.
 
IMO.... 99% of the loo problems stem from the rubber weighted valves at the head of the hand pump itself. Had to change another one yesterday...

All components are avail from Jabsco so you don't have to do a complete change.

I've found the twist and lock spindle seals only last a couple of years, two replacements arrived in post today - made in China.

Bollox!! That is total rubbish. If you have cracked the base, through being, mechanically inept, it is down to you....

No fault of the bog...

Thank you for you kind words...

I think you will find - if you think carefully about what I wrote I didn't say or suggest that I had cracked the base. What I did say was that sometimes the base sections of the earlier Jabsco pumps cracked, and I meant through age or use. What I said might have been slightly ambiguous - but I certainly didn't mean to suggest that it was the action of screwing the new pump on that cracks the base.

Furthermore what I said about the later pumps not fitting the earlier bases is true. The suggestion that you should 'definitely' just fit a new pump doesnt apply to many older Jabsco toilets - or at least it isn't the necessarily the better option.

For your information I have never cracked or broken any part of any if the various Jabsco toilets I have installed or repaired.

Perhaps you should apologise for your unwarranted insults about my engineering and fitting capabilities? At least you perhaps ought to think twice before you are so rude...

Sorry I suggested just replacing the pump as it seems to have triggered off an unnecessary spat! The OP did say that he thought the new pump was identical to his old one, so the replacing the pump for £55 is an alternative to £100 for a new one - espaecially if the builder never expected to replace it! Of course sometimes the bottom mouldings do crack, but usually the failure is in the pump.
 
Mine needed a new pump, a new inlet spigot and a new seat/lid. I would probably have had to replace the seals as well.

I felt guilty binning the old loo. But I'm getting over it. The bruises on my arm from changing the pipe are also fading.

[The new loo was £99 and the pipe £80. As they say 'Go figure']
