No wonder this diesel engine was constantly overheating, half the water jackets were partially to fully closed with calcium built up over years. Important to note is lack of use results in water sitting idle in your diesel engine. Like stagnant water on land, the effect can be noted in an increase in "undesirables".
My nightmares of underused salt water cooled engines, include visions of the salt sitting on metal - yikes! Over time, water evaporates increasing internal salt levels. The judge of this case issues the innocent diesel a life sentence - corrosion!
In this tip, Robert teaches how to identify and prevent internal engine corrosion. Add to this a yearly flush with fresh water, and you are well on your way to increasing reliability and maximizing the life expectancy of your marine, diesel engine.
