the new impellers have some sort of boss in the middle that the new tool fits into for removal. So it only fits the latest impellers.

I changed both mine at the weekend and needed nothing more than two screw drivers. each came out in about 10 seconds. Not sure it's worth investing in a tool to do the job?

I had a go as well and tried the method in the volvo manual i.e. with the water pump pliers. Could not get the impeller free. Tried using the two screwdriver technique but was putting so much pressure on the housing I was worried I would damage it. All this on a warm sunny day with the boat out of the water. That got me thinking about trying to do it in adverse consitions and in a hurry hence the question about the volvo puller. I still cannot think what this tool looks like

I have the Jabsco puller and find it very good. I always used two screwdrivers but found that when I changed my boat the larger engines had very large impellors and screwdrivers did damage the impellors, so I invested in the Jabsco. I have no idea what the £7. Volvo puller is like, but if Volvo are selling it I would think it must be up to the job! are you sure £7. is not just the deposit!!!! We are talking about Volvo!
I have always found that putting back in a new impellor is the hardest bit of the job, so I purchased a tool that is made for inserting rings on a piston, it can be bought from almost any car spares shop. Lube the inside of the tool well, KY is fine! clamp it down and line it up with the spline and just push the impellor home! makes the replacement job very simple.
Good Luck

Just wop a slurp of fairy liquid in there and turn them around. Then plop them out with a couple of blunt screwdrivers or bike tyre levers. Use f/l on the new ones but ONLY fairy liquid as its mild on your hands. Save any good worn ones for emergencies.

it is sosimple that you wonder why all impeller and not made to be removed this way and is ideal for confided spaces
you have to check which impeller mainly the larger ones you have and the puller are matched to them
it is simply a bolt with a nut which has a male thread that screws into the impeller which is threaded to take the puller

I bought the Jabsco tool 5 years ago, and it was a worthy investment. Screwdrivers will work but you risk damaging the impellors and more importantly the housing.
Medskipper is right in that the hardest job is putting them back in. His idea of using a piston ring compression tool is a good one - I hadn't thought of that. I found a way using a jubilee style clip that has 2 adjusters. I may buy a piston ring compressor for the next time I take them out, which I doubt will be far away ;o)

Machine mart £8.50. Bought one few weeks ago. Fine. Someone posted the link a few months ago.

har har, the "impellor removal tool" is a bolt, that screws into the end threaded bit of the latest batch of impellors. I'm stuck oop North at the moment, can post a piccie tomorrow.
It does work, but not on older ones (e.g. the one I bought last season).

I've used the "two screwdrivers and a J-cloth" method for ages, and it's fine for impellors that come out reasonably easily. The problem comes if you need to apply more pressure, you can end up making a "ding" on the corner edge, which can take chunks out of the impellor blades.
