Impellers last 4-5 years, unless you run them dry or in silt.

What HAT said.
If it runs fine on the hose, but gets hot at idle, it must be a low speed flow issue. Did somebody replace the engine water pump with an automotive one?
If so, probably not a stainless or bronze impeller, and has rusted away.
