Just wondering if anyone would know what would be the best impeller for me to use. I have a older 93 gts that I got for my kids to get on the water with. It had a 580 and topped out at about 30mph. I removed the 580 and replaced it with a 657x. What impeller pitch should I be looking to change to? I know the stock impeller isn’t going to move them very well

Impellers are not something I have a ton of insight on. However, generally speaking Sea-Doo did a good job of selecting the impeller for the hull that it will be on.
Even for a 580, 30mph is too slow and I would assume there is something else that needs to be looked at before swapping impellers.
That said your impeller may have some cavitation that is contributing to the slow speeds. There's a lot of info about that problem around the forums. do some looking into it and make an inspection of the impeller and wear ring in the pump.
