2. Lowest water level
ECM00290
CAUTION:
If the fresh water level is below the level
of the anti-cavitation plate, or if the water
supply is insufficient, engine seizure may
occur.
5. Cooling system flushing is essential to
prevent the cooling system from clog-
ging up with salt, sand, or dirt. In addi-
tion, fogging/lubricating of the engine is
mandatory to prevent excessive engine
damage due to rust. Perform the flush-
ing and fogging at the same time.
