I have a farymann diesel
, 1 cylinder in a sailboat I recently aquired. it is raw water
cooled and had not been started for about 18 months prior. in the last 30 days that I have been working on the boat and run the engine
is chalky white. there is not a visible sheen on the water
and the chalkiness dissipates quickly in the water
. I have run the engine
for 15-30 minute periods and the color of water does not clear up. I have plumbed a fresh water flush system into the intake hose and hoped that may clear things up.
the engine oil
does not indicate water intrusion.
anybody know what the chalky white water means?
