I have this old fresh water cooled 170HP Mercruiser inboard, that runs
great.

I replaced the impeller, and still no water circulates into the heat
exchanger. I looked for clogs, with no luck. I removed the old stator
charging circuit, which I had replaced with a standard alternator this
past summer.

So my question is can I install a radiator with an electric fan to
eliminate the salt water altogether? If so, any tips?

Thank you

It wouldn't be practical. There are, though, completely closed cooling
systems that do not require the usual sort of heat exchanger.

The exchanger is mounted outside the boat, on or along or adjacent to
the keel. No outside water enters the system anywhere.

But then you have to accommodate the exhaust. There are "dry" ways to do
that, too.
