Recommend a cheap 12v oil and water suction pump?

[Murv]

Hoping to get both birds with a single stone here...
So, as title, all the oil suction pumps I've found will only work on oil or diesel as they use the fluid to lubricate the pump.
Anyone recommend one that I can use for oil changes, but also to suck the last of that pesky water from the bilge?

In my experience a cheap 12v pump will not lift oil. Best to go for a Pela or similar vac pump. Good for oil and any other liquid including bilge water. About £30 in Force 4.

Thanks for that rafiki, I did wonder if they'd have the torque to pull oil out quickly enough. I've ordered a Pela 6000.

I used to use a pela pump - and they work fine just a bit slow. Took volvopaul's advice and bought a jabsco water puppy type pump. more expensive but really fast for getting old oil out and pumping new in. less mess quicker etc. I even used it on cold oil last spring and that didn't phase it either. also brilliant for sucking gunge out of bilges, tanks etc. wish I had bought one when I bought my first boat 15 years ago.

I have a simple hand pump to suck oil from my engine and gear box with a change over valve. I use a wet and dry vacuum cleaner to get the last, infact most or the water out of my bilge. My wet and dry is a 1000w mains that I run off a generator.

I also have a 12VDC jabsco gear pump to transferring diesel from cans to my tank. Much cleaner than poring it through a tundish.

I had an electric jabsco water puppy / mini puppy pump that came with the boat and it's a real godsend.
9L of oil drained directly from suction tube on each engine takes less than 5 minutes each.
No effort!
I mounted my pump in a neat wooden box with a removable lid and a switch. The plastic hoses just coil up inside and it stores really neatly.
When connecting I just hook up the clips to a power supply in the engine bay, connect the suction and feed hoses and press the switch.

I've used it for cleaning all sorts of spills, draining the final bit out of the bilges etc and it even pumps gearbox oil, albeit a bit more slowly.

Thanks all, I'll see how I get on with the pela pump although by the time I've pumped 40 litres of oil out, I'm fairly sure I'll be irritated sick and ordering one of the electric Jabsco's!

It will take longer, but just go and make a cup of tea and relax. The worst part is pouring the oil into a container from the Pela. But for a once a year job I can put up with that.

That's very true. And I can use that time to reflect on the saving I've made over the electric one!

The whale gulper is a fairly capable diaphragm pump. I had one on my last boat installed as a bilge pump with a wandering hose that would reach anywhere inside the engine bay. It also doubled up as shower sump pump for the forward shower.

To use it for oil would be tricky because a separate discharge would be needed.
