"When I sail my yacht in a rac
"When I sail my yacht in a race or regatta, I always get calls on the VHF that I have left my sea cocks on the cooling system closed, as a very visible 'steam' vapour comes out of the exhaust. I know this is simply the relatively warm exhaust sea water condensing in the cooler atmosphere, but I wonder why the other directly cooled engines do not exhibit this characteristic. The engine runs fine, has a new thermostat in it, and if anything overcools even on long runs.
I've checked the archives for some comments on this, without success. I've been told to run vinegar through the system to remove the salt. The sacrificial anodes on the cooling system are replaced regularly.
Is the 'steam' engine effect just something one has to live with?
Regards"
