Unhappy Spark Plugs And Water Dont Mix

Just Working On My 525sc To Find Out Why Oil Temp Climbed All Of A Sudden Yestarday And Decided To Change The Plugs While I Was At It And Found One Plug Too Have What I Think Is Water Getting On It And Burning,head Gaskets Were Done 50 Hrs Ago,seems To Run Good Under Throttle,no Water In Oil,does Load Up After Idling For Awhile, Could This Be A Head Gasket Seaping Or An Exhaust Header Leaking,I Have Cim Headers,THE HOLE IS NUMBER 6

Can Headers Be Repaired Or Do They Have To Be Replaced?

You can have them repaired by a good welder who is familiar with marine exhaust systems. The headers tend to crack near the welds.
