Hello, I have a Palmer 1958 ih240 that has always been raw water cooled.The original owner took great care in winterization for the past 35 years while in service on the prettiest 24' d.east picnic boat your eyes have seen.(Rudder Mag. plans ,1954) I began running this boat again this year but would like to internally cool the engine to prolong it's life. Currently the raw water overflow drops into the exhaust and the motor runs at 140 degrees.Should I make the change? If so can anyone give me some directions? Tom

I had a similar situation with a Palmer P-60 in
my 1970 Morgan 30.
I converted it to fresh water, but discovered a real snafu in the heat exchanger. The recommended exchanger allowed the engine to overheat under load.
So if you do this you must use an oversized heat exchanger and a second water pump.
I finally threw in the towel and reverted back to saltwater cooling.
It has worked for 37 years, so I think that the Fresh water conversion was an interesting exersize in futility.
