just found out a used sportsman 700, I've had now for a few years, is an Earnhardt edition...
lost the water pump and over heated last year, started fixing it all this year, melted the impeller down to the shaft and the Nylon out for the nut
fun part is the Vin shows parts department that it is a much smaller nut for the water pump impeller...
Question is : does someone make an oil/water pump upgrade ? with a larger shaft for both the oil and water pumps? That fits Polaris.
the shaft fits the stock water pump impeller snugly, just has a larger thread at the end.

anyone come across this before?
