Our power boat
, a 44ft trawler
style, took sea water
up the exhaust
while stopped in a seaway. The motor
a Caterpillar 3208 N 210 hp was not running and water
was cleared promptly by removing engine
components and physically barring the motor
over. It then started successfully.
Since then we have changed the oil
twice and an oil
analysis showed 5% sea water was present. We have changed the oil again (a third time) and await further analysis.
We have been told that Cat 3208's can have a reduced amount of riser in the exhaust
system and have now fitted a rubber flap on the exhaust which appears to work well.
The motor starts very easily and appears to run well . All gauge readings show the correct levels.
My question is should we do doing anything else to prevent engine
damage or deterioration?
