I have a Satoh s650g that the water pump froze up. i took it apart to replace the bearings and I broke the impeller doing so. I can not find an impeller anywhere in the market. I do not want to pay for a rebuilt one as they are way over a hundred bucks. I also know that a Case IH 284 is the same engine and parts but that is no help either. If you have any information on where I can get an impeller please let me know. Thank you for taking the time to read my post.
