Marc, I have this problem on Volvo
engines. At each end of the heat exchanger are rubber caps with two hose clamps. The small clamp keeps sea water
in the heat exchanger tube and the large clamp keeps the anti-freeze in the cast iron body of the exchanger. If the small clamp isn't put on just right, sea water will leak around it and go into the antii freeze and fill up the reservoir. When it fills up water comes out the pressure relief hose and goes in the bilge
. If your Westerbeke has same setup, make sure your small clamp is on tight.
