Hi all
I acquired a 95 SPX that I got running last fall, but there was still work to do. I've since replaced the wear ring on the advice of folks on this forum as a correction for possible cavitation. In another response I was told that I probably needed to replace the impeller, which was pretty dinged up. I came across a brand-new impeller on ebay at a "can't be beat" price. It was a Solas Concord 14-22 pitch (Solas SD-CD-14/22 Concord). Per the compatibility chart on ebay, it was applicable to the 95 SPX. If you go to Solas website, however, they don't recommend the Concord 14/22 for the 95 SPX (657x engine), rather the UK 14/19. They DO recommend the Concord 14/22 for the 717 engine. I don't know a lot about these variable pitch impellers, but I know that on boats if you are over-propped you won't get the motor to spin up to the proper RPMs, and lugging the motor with too high a pitch will eventually cause its death. Given that there is a 5 HP difference between the 717 and the 657x motor, do you think I am okay running the 17/22 impeller on my 'doo? I haven't installed it yet because I didn't want to disassemble the pump yet again without having run it at least once...
Thanks in advance for any bits of wisdom.
