Turning a Mag 3 into a 5 or 7

[CeeGee]

I heard that this is possible.

Can someone explain how and what parts would I need to do so.

The reason being is that I have both a 3 and a 9.5
I was going to run the 9.5 on my return from my sump but it may be too powerful and I doubt the 3 would be powerful enough if I had to switch it.

Thanks,
C.G.

Should've got the eheim but I didn't know they were a better pump.

Mag Drive parts here

3->5 replace mag3 front cover with 5/7 front cover
3->7 above plus replace 3/5 impeller with mag 7 impeller

When you are all done, order the Eheim!

Thanks.

That site shows the 3/5/7 has the same size as the 2. Is the 2 convertable as well?

Never tried it. It very well may be.
