Another water presence signal, becomes from starting difficulties as due to some roost
on the exhaust valve, the compression does not reach the proper burning value.
Spraying some lubricating oil into the cylinder while insisting with the starter, very
often the engine can be started. Better if the operation is made acting on the decompression
device, for allowing some free engine revolution for better distributing the oil and adding the
flywheel kinetic energy. When started the valve self cleans, but in some cases, of too long
time water presence, also the piston rings are locked from roost, so the engine must be opened
for repairing.

In some cases the engine does not start for external reasons like lack of fuel, air
bubbles, too flat battery. While insisting, the water pump deliver a certain quantity of water,
that is not pushed out by the engine exhaust pressure, remaining trapped into the exhaust pipe
even if correctly fitted. If that happens, drain the exhaust pipe when giving up the
unsuccessful starting operation.

When the installation is correctly planned and carried on, surveying the result during
the first operative season, the generator on board give many troubles operative seasons,
requiring lubricating oil and fuel filter replacement only, but there is another up keeping
operation that prolong considerably the unit life. It consists in a "wintering" but useful in
summer too if the set remains unemployed for more than two months. Due to temperature
difference between night and day the water remaining into the exhaust pipe and muffler water
lock causes condensation, that on the engine exhaust valve, produces roost. Spraying into the
combustion chamber some lubricating oil, and disconnecting the exhaust pipe, moving the
piston position by the handle or a flash starting attempt, avoids completely the roost risk for
long time.
Consider that on the marine engines employed for the nautical generating sets, there
are no critical connections between cooling water and fire zone, so in case of some gasket
breakage there is water sprayed out of the engine, around it into the hood and never water
entering into the piston or the sump zone.
Our technical staff is in any case at customer's disposal for additional suggestions or
solving out of standard cases for getting the complete satisfaction result, that can be always
reached putting more attention on the plant, or adding special accessories like a dry exhaust
pipe and similar.
