I have an aluminum "B" cut impellor that looks like new but is used. It's in a 12JC on my garage floor right now. There's something wrong with the pump, not sure what's wrong with it. It makes a slight scraping sound when it's turned. Also, the pump's intake was cracked at some point in it's life and it was professionally (looking) repaired. $140 for the pump (pump housing, impellor, impellor shaft). Maybe you know how they come apart ( ? ) and you can buy the impellor from me for $40. I also have a stainless "B" cut impellor that's in a 12JB on my garage floor, turns very tight - not sure if it's set up that way or if there's something wrong with it, I'll sell you that pump (pump housing, impellor, impellor shaft) for $625. Maybe you know how they come apart ( ? ) and you can buy the impellor from me for $450. I also have a 12JC that's still in a rotten hull and I need to pull it out. That pump hasn't been turned by hand as of yet but the engine runs and there are no abnormal sounds coming out of the pump. Aluminum "A" cut impellor with a some chips in it, nothing major, should be ready to drop in and go for $220 (pump housing, impellor, impellor shaft). In my Rogers I have a 12JC that was rebuilt and had two lake trips put on it, new aluminum "A" cut impellor, RTR drop in and go, needs to be pulled out of my hull, for $350 (pump housing, impellor, and impellor shaft). That pump performs as new. Maybe there's something in here you can use/help you out. 619-787-7987 Rod thanx@cox.net
