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

To your question the answer is no.
Does water pump to the heat exchanger? You need to undo a hose to know.


Yes, I have done that. I took it apart and ran water through the heat
exchanger. The engine stays cool. I also ran water downwards to the
intake, and it flows. If I use the muffs and try to pump water up, there
is no continuous flow at all.
