    I shredded my first impeller on the Universal M-18 with an Oberdofer raw water pump. What a pain to fish out all the little bits of impeller from the exit port and hose!

    Silver lining - I found this source for replacement impellers at a reasonable price:
    https://www.ebay.com/itm/Impeller-K...eAAAOSwcj5ZTr~Z:sc:USPSFirstClass!76210!US!-1

    They have an assortment for other engines and pump models too if you don't have the M-18/Oberdorfer.

    Don’t know if i’d Want an unbranded generic impeller. I’m afraid of the hub spinning or loosing blades. I think I’d rather have a globe impeller than this. Go to depco or pumpsandpartsonline for quality parts.

    I see your point. These parts are consumables and meant to be regularly replaced. I'll check out your recommended source. I don't want to be penny wise and pound foolish.
