Hi again.

Just had a good look at those.
Pretty impressive pieces of kit, especially the 45TE and 45TEF, which can be used to break a circuit as well as make one.
The contacts are rated for 2A at 240V AC. They don't give DC ratings, but I'd be wary of using them to directly operate a cooling fan. Pop a relay in the circuit, to be safe.
Perfect for bulbs, buzzers, etc.
I wonder can they be got on this side of the pond...

Hi

Yes, similar to it, but without the plastic bezel and with only one switch, for high temperature.
Those look very good. I haven't seen them before, though they wouldn't look the part in my usual environment, I suppose.
I'd say they're specifically aimed at industrial applications, where appearance is a minor consideration!
I don't have time to look at the spec right now, just grabbing a few minutes between jobs and eating micro-waved food in front of the lap-top.
If I'm still awake when I get back from the next one, I'll have a proper look.
Thanks for the link

Oops.
Sorry.
I meant to send two links.
The one I sent was for the gauge without a switch built in, which I sent because it has a picture of the unit.
Here's the link to the gauge with the switch, but it has no picture, sorry...

Hi

Try the likes of VDO, or Faria, who do a range of gauges and appropriate senders.
I've only seen these dual function senders for oil pressure, never temperature, but you never know until you try...
If this doesn't work out, then how about old fashioned technology? A Murphy "switchgauge" is a completely mechanical device, using a bulb and capillary tube to operate a gauge, on the needle of which sits an electrical contact. There is a second contact on a user positioned arm, inside the instrument. When the needle touches the arm it makes a circuit, which you can use to energise a buzzer, or light a bulb, or both. Far easier to understand than to explain!
The only down-side is you need to find a way to accommodate the bulb, which is quite bulky.
If you can manage that, though, you end up with a "historic" looking instrument panel, in keeping with the Lister's appearance, as Murphy never updated the appearance of these instruments.
All the types I've mentioned are commonplace on boats, so a marine chandlers would be a good place to start the search.
Good luck

Hi Casey

They already have the pump!
I gave it to them.
Plumbing it in is a DEFINITE engine out job, meaning booking a space next to the hoist, for however long it'll take.
The H&S brigade have stopped all Heath-Robinson lifting solutions in the marina and only the approved hoist, or the crane, both with costs attached, are now allowed do any heavy lifting. So far, the barge has been in use every time the hoist was available. That obviously won't be the case now, so maybe I can talk them in to booking the space and use of the hoist for half a day.
Better weather seems to be coming now, too, so the boats will be in use and the hoist may not be so busy.
I'll just give them a nudge...

Hi dieselgman

Yes, we know he can't leave the contaminated oil in there.
It's just that, given the difficulty of changing it, he wants to be sure the problem is solved first, so he doesn't ruin the new oil straight away!
An oil drain pump has been on the "to do" list ever since the first time he serviced it.
I also intend to fit a remote oil filter and oil cooler, to help it run cooler and solve the skinned knuckle problem with the present arrangement.
Honestly, whoever designed the boat must have attended the Peugeot/Citroen design school. No thought at all seems to have been given to access for servicing and sharp edges abound!
Thankfully, I don't have to get involved much, as the brother-in-law is pretty competent.
Thanks for all the guidance

Great
Thanks for that
I'll pass it along.
Whereabouts is "we"?
Is shipping to Ireland possible?

North Longford, in the middle of Ireland, right out to the West of Europe.
No Listers myself, but my sister's narrowboat uses one for propulsion.
Most people over here don't consider Listers in general to be "engines" any more. They're museum exhibits, or mobile exhibits for classic machinery shows.
That's where I picked up my interest in them.
I'm trying to persuade the owner of a retired Lister powered welding plant to part with it...
