One sold on eBay recently for $104.
What all is wrong with the pump? If it's just leaking, I'd think you could just buy a regular car/ Jeep V6 225/231 Buick/Kaiser water pump and swap the brass impeller over. Not sure 100% on that though.
Or even just use the automotive pump if you boat in fresh water, and just pull it off again next year and see if it's surviving ok.... wouldn't try it in salt...
