I assume I will have to have the stock SS wear ring pressed out of the housing , it is 0.02" out of round and teat was my problem it was binding the impeller so I need to replace it. I was looking online for a wear ring but it says it only fits aftermarket pump housing not the stock pump housing I have besides going to the Yamaha dealer witch has to order it anyway for $212.80 plus tax is there anywhere I can get a new wear ring that will fit my stock 144mm pump housing?

PS: web links would be great
