Fuel system purge

- Check the fuel level in the tank.

- Open the fuel cock, unscrew the purge screw lo­cated on the upper part of the filter and pump the sys­tem using the incorporated pump. When no more air
bubbles appear, tighten the screw. In the event that
the injection system is not fully primed, carry out the
following procedure:

- Unscrew the No. 1 injector fuel pipe and turn the
engine on the starter until diesel fuel appears. Re­tighten the nut and follow out the same procedure for
the other injectors.

- Re-start the engine and check for leaks.

I DANGER : Do not smoke, approach with a naked

flame or cause a spark. Wipe up any spilt fuel.

COOLING SYSTEM

This is made up of two different systems: the sealed
cooling system and the sea water cooling system.

Sealed cooling system

This is made up of a pump driven by the crankshaft
via two V shaped belts, a water temperature heat
exchanger, an oil temperature heat exchanger inte­grated unto the engine block and a thermostat.

Seawater cooling system

This is made up of a pump, a clear - salt water heat
exchanger, supercharger air refrigerant, power steer­ing oil refrigerant (version Stern drive), reversing gear
oil exchanger and an exhaust elbow.

Coolant

Recommendations for initial start up.

- Check that the drain plug located beneath the turbo,
open the breather plug on the top of the turbo liner.

- Create a diluted 50% antifreeze and 50% clear wa­ter antifreeze mixture. The quantity required is given
in the table of technical specifications.

- Pour the mixture into the filler hole, close the
breather plug on the top of the turbo liner when the
liquid can be seen and continue filling up to the maxi­mum. Possible top-ups should be made when the
engine is cold and only with clear water. Re-start the
engine and top-up to correct level. Check for leaks.

- Every two years at the beginning of the season,
completely drain the cooling system, flush out using
clear water and re-fill in accordance with the instruc­tions provided above,. (See SILVERWAKE guarantee
terms.)

I

DANGER : Always fill the cooling system when

the engine is off and cold – Do not smoke or ap­proach with a naked flame.

- Keep away from revolving parts when the engine is
running

.

I CAUTION : Never use undiluted antifreeze. The

use of additives and other type of coolant can cause
insulating deposits to be formed, and engine over­heating.

Hot water connection

You can install an onboard hot water system by con­necting from the interior clear water system to the
engine (Ask your NANNIDIESEL agent).

I CAUTION: Before staring the engine, make sure

that the sea water inlet is open as it only needs the
pump to run dry for several seconds in order to cause
deterioration to the water pump rotor.
After cleaning the sea water filter, carefully close the
cover in order to avoid the water pump sucking in air.

warning lights stay lit

.

I CAUTION : Discover and solve the problem be-
fore starting the engine!

Check that the seawater is running through the ex­haust correctly.
Let the engine idle for 2 to 3 minutes, then subject it
to a load straightaway.
If the engine does not start at the first attempt, try
again making sure to switch off between each at­tempt.

IMPORTANT:
In the event of several unsuccessful attempts at start­ing the engine, look for the reason.
Do not keep on trying as water could be sucked into
the engine through the exhaust system!

I WARNING: Never switch of the electrical system

using the battery cut-out whilst the engine is still run­ning as this could cause damage to the alternator.

IMPORTANT: Do not let the engine idle unnecessar­ily without load.

STOPPING THE ENGINE

- Move the lever to the idle/neutral position

- Let the engine idle for few seconds so that the tem­peratures and turbo speed can stabilise.

- Never accelerate the engine before switching
off.

- Turn the key to the "O" position (vertical.)

- Switch of the battery isolation switch, close the sea
water inlet valve as well as the fuel supply.

IMPORTANT: In the event of the vessel being towed,
stop the engine and ensure that the seawater inlet
valve is close so that the engine does not accidentally
fill up with seawater.

TWIN ENGINE VESSELS:
In the event of running on only one engine, close the
sea water inlet of the stopped engine. Do not forget
to re-open it before re-starting the engine.

I CAUTION : Check the engine and the engine
compartment for possible leaks.

RUNNING IN
SERVICING UNDER GUARANTEE

Running in

We recommend that for the first 20 hours of running
you treat your engine gently and only run it at maxi­mum speed for very short periods.

Never race the engine immediately after starting with­out having let it warm up first.

IMPORTANT : After running, the engine should not
be constantly run at its maximum speed but at 200

RPM below its maximum speed

.

Servicing under guarantee

All preventive maintenance operations as well as
their timescale are given in the: SILVERWAKE. ®
Guarantee Booklet

The guarantee is conditional on these servicing op­erations. They must be carried out by an approved
NANNI DIESEL representative
All new engines are guarantee against all component
defects in accordance with the terms laid down in the
SILVERWAKE. ® Guarantee Booklet which is given
to the purchaser when the engine is delivered.

6. MAINTENANCE

I DANGER: To avoid any bodily injury, let the en-
gine cool and close the battery isolation switch before
carrying out any work.
Observe safety and environmental protection recom­mendations

IMPORTANT : These recommendations are vital.
Compliance will lengthen your engines operational
life and ensure that the conditions necessary for
meeting the normal guarantee terms are fulfilled.
Do not make any unapproved modifications to the
engine.
Damage caused by the use of unlisted or non ap­proved spare parts is not covered under the terms of
the guarantee.
All interventions and maintenance work should be
carried out by an approved NANNI DIESEL workshop

If the engine is used for a number of hours that is
less than the indicators provided, maintenance
should be carried out once a year.

In this case, we recommend that maintenance work is
carried out before laying up for the winter, the engine
will then be protected by new, clean lubrication oil.
This does not obviate the wintering operations laid
down in the SILVERWAKE guarantee.

splashes into the eyes, rinse abundantly with water
and contact a doctor immediately. Do not create a
short circuit.

RECOMMENDATIONS

In order to ensure that the alternator an its incorpo­rated regulator work perfectly, Never:

- Switch off the battery cut-out when the engine is
running (risk of damaging the regulator irrevocably).

- Reverse the battery terminals. The terminals are
marked + (positive) and – (negative) respectively;
the negative is the earth; the cable connectors and
the cables themselves should be attached correctly.

- Change the load on the circuit whilst the engine is
running.

To use several batteries, install a load proportioner.
(Ask a NANNIDIESEL representative).

In the event of starting using a back-up battery and
jump leads, carry out the following procedure:
Ignore the main battery circuit, link the backup battery
by connecting to + and - to -.
