Years of other owner's neglect and mine have lead to little or no salt water
running through my 27. She is located in San Carlos, Sonora, Mexico and I
visit- and work on her 2 or 3 months a year. She sits on a trailer. I have
checked and replaced the impeller, checked all hoses and elbows. removed the
exhaust manifold and cleaned out what I can see. I have be advised to run
Sulfamic Acid, in a solution, through the cooling system-- haven't done this
yet -- Others suggest Muriatic Acid but warn of losing gaskets. Other than a
total removal of the engine and machine shop "cooking" --- I've run out of
ideas-- Any suggestions?? Ralph
