Hi All, I saw this thread whilst looking to repair my own Canadian Spa V2 with incredibly noisy rotor, as seems to be the norm, Canadian spa refused to sell me parts or even help unless I sent the whole thing back to them (at great cost) for a diagnostic. I argued that I did not need a diagnostic and was not prepared to pay for it as I knew exactly what the problem was, but they were having none of it. So here is my own experience for anyone who may be interested. So I took a chance and purchased one of these: https://www.amazon.co.uk/RDEXP-Magnetic-Impeller-Submersible-Replacement/dp/B01E6V649Y/ref=sr_1_2?dchild=1&keywords=16mm+magnetic+impeller&qid=1603265200&sr=8-2 Although the magnet is slightly smaller, the impeller part is exactly the same size. I used the rubber caps off the original part as the new ones were too small. In order to stop the magnet dropping down too far, I cut the end off one of the new rubber ends to make a spacer and slid that onto the shaft under the magnet, then put it together and tried it. It has now been running for 24hrs and is nice and quiet with a good flow rate. To test it I bridged the inlet and outlet ports with a pipe, filled it full of water and just left it pumping it round and round. Today I will plumb it back in to the tub and fill it all back up. I do not know how long this will last, but if it lasts 6 months then I will be happy, for an outlay of under £4. I accept no responsibility if anyone tries this on their own hot tub and it all goes balls-up. You take my experience entirely at your own risk.
