I am buying a used boat from Stony Point, NY. It has a Mercruiser V8
5.0 with 190 HP with 300 hours on it.
I live in Greenland. An island in the arctic region east of Canada
where the seawater temperature is around 36-37 F degrees. And that´s
where there might be a problem. I am told that the motor is "use" to be
cooled of with warmer water temps around the more southern part of the
world. And when I get the boat and the motor is cooled down with
seawater that is 36-37 F degrees then it migth not run smooth anymore
or develop somekinda problem. Is this story a myth or is there
something to it? And if the story is right how can i prevent any
problem with the motor. I cannot install fresh water cooling system as
it is too late for this motor because it has already 300 hours of
seawater cooling I am told.
Any help or suggestions will be much appreciated.

Sal****er cooling is 'uncontrolled' water circulation drawn from under the
boat- with very little control of the engine operating temperature. If you
are concerned about 'stabilizing' the engine temperature, the only way to do
it is by freshwater cooling. This will allow the engine to run at operating
temperature (controlled by the thermostat) and at least run more efficient.
And it is NOT too late to do this.
