My engine was overheating and when I pulled the heads and water jackets and identified swelled deflectors. In my search with local dealers, most did not have them, some did not know what they were and one told me that when they rebuild Johnson/Evinrude motors they use 5/32 fuel line instead of deflectors. My question is can you use 5/32 fuel hose for the deflectors, or do they fail prematurely?
