Routine Maintenance; Winterising/Dry Storage - Williams TURBOJET Manuel Du Propriétaire

Lifting the Turbojet
Instructions for the correct use of lifting strops are
contained in the strop bag; please read these
carefully.
CAUTION. Damage to the tender may
result if the following procedure is
not adopted.
Lifting strops are available as an
optional accessory. Ensure
fastenings are attached correctly
before lifting.
WARNING. Risk of
injury or death. When
Williams lifting strops are used please refer to
instructions supplied with the strops and adhere to the Safe
Working Load values as follows: All Turbojet models: 750 kg max.

Routine Maintenance

To ensure a long service life and to
maintain the tender in a safe and reliable
condition, please follow these routine
maintenance instructions. Williams
cannot accept any responsibility for
damage or injury resulting from incorrect
maintenance or improper adjustment
carried out by the owner.
1 Wash the tender regularly with fresh water
to remove salt deposits.
2 Check engine oil level. When topping
up, follow the engine manufacturer's
recommendations. Engine must be at
running temperature when checking
oil level.
3 Check coolant level.
4 Flush open loop cooling system.

5 Apply a good quality marine grease
containing Teflon (eg Quicksilver 101) to all
control cables, both under the helm and at
the pump.
6 Check bilges for water ingress, oil or fuel
contamination and clean if necessary.
7 Lightly grease the extending running light
pole base using white grease or similar.
8 Check the condition of all anodes.
9 Loss of tube pressure over 24 hours is not
unusual. Temperature and atmospheric
pressure will affect tube pressures. Check
pressures regularly.
10 For boats used in tropical environments,
the frequency of routine maintenance
should be increased accordingly.

Winterising/Dry Storage

Store the boat covered in a clean, ventilated
and dry place that is not affected by major
variations in temperature or humidity. For full
information on servicing please refer to
the Rotax engine service manual.
GENERAL
Carry out a thorough inspection of the engine
compartment and bilges to ensure they are
clean and completely dry. If possible, raise the
front of the boat to allow any residual water to
drain towards the stern where it can be easily
removed.
BUOYANCY TUBE
Prior to storing over the winter periods, the
buoyancy tubes must be deflated and hosed
down with fresh water, removing any small
stones and weed from the luffing track, then
allowed to dry. Use a proprietary tube cleaner
and polish to ensure optimum condition. Store
with the tubes lightly inflated where possible.
UPHOLSTERY
Where possible, remove all upholstery from
the boat and store in a dry place. Ensure
upholstery is cleaned using a proprietary
upholstery cleaner and is fully dry before
storage.
MAINTENANCE OF THE
HULL AND DECK
Wash the deck in warm water after use,
using a mild detergent and hose down to
remove sand etc. The hull and deck should be
regularly polished using a good quality gelcoat
polish to minimise fade and UV chalking.
BATTERY
The battery used in the Turbojet is of the
dry cell type. This means that the electrolyte
content is absorbed in a special fabric which
requires no topping up and is leakproof in any
position. When the boat is not being used for
an extended period of time, disconnect the
earth terminal. A trickle-charging device, such
as an Accumate, will extend battery life.
FUEL SYSTEM
Fuel will become stale over a period of several
months. A full fuel tank prevents moisture and
mildew from developing within the tank. Fuel
begins to break down after approx. 30 days.
Adding a fuel stabilizer in the recommended
ratio will minimise this.
COOLING SYSTEM
Flush the open loop water circuit to remove
salt, sand, shells and other contaminants
that may be trapped in the raw water cooling
circuit (refer to Exhaust System Flushing
section).
Measure the anti-freeze content of the engine
coolant with a commercially available anti-
freeze tester. A 50/50 mixture of distilled water
to propylene glycol provides sufficient frost
protection to approx. -37°C.
ENGINE OIL CHANGE
It is important to change the oil. Used engine
oil contains water, unburned fuel and small
metal particles. When old oil is left in the
engine for longer periods, corrosion and
degradation of bearings within the engine may
occur.
CONSERVING THE CYLINDERS
Unscrew the spark plugs and fill approx. 10ml
of clean engine oil directly into each spark plug
bore. Crank the engine a few times with the
starter. Screw in the spark plugs again.
GREASE CABLES
Grease all control cables at both ends and
exercise to ensure good coverage
GENERAL CORROSION PROTECTION
Apply Vaseline, dielectric grease or a similar
white grease to battery isolator switch,
upholstery press studs and running light pole
base. Use maintenance spray on key switch.
Apply a proprietary corrosion guard to engine,
electrical connections, under helm and around
jet pump area.
