" A sea-water cooled MD2B, circa 1976, has developed a tendency towards overheating. Thermostat replaced, water pump ok, sea-water filter clean. No water in engine oil yet. Engine starts and runs fine; temperature wanders within 1/2 hour under load. Diagnosis please? An acid bath to clean out water passages? Other ideas? "
