"sea water intake got blocked
"sea water intake got blocked and burned out the inpellers in both engine,reached temp of 100.
Reolaced impellers and did a pressure test on fresh water coolant system ,lost no pressure.No water in oil no oil in water.opened heat exchangers and got out broken parts of inpeller.Removed thermostats and slightly inproved but at 3500 revs temp went up to 90 before i slowed down to 2500 revs ,temp back to normal.I have also lost about 10 knots at full revs.cooling sea water appears to be coming out at a good rate,and i don't appear to be loosing coolant.There is no miss on the engine but some steam is coming out the exhaust.Have also renewed the exhaust hose from turbo to muffler box."
