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
Textron engine service manual.
End of
Buoyancy Tube
year
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 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.
•
Maintenance of the Hull & Deck
•
Wash the deck regularly using a mild detergent in warm water 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 leak proof 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 After Use: Flushing Procedure 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. Run the same 50/50 antifreeze mixture through the open loop system using
•
the flush attachment and a suitable container.
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.
Conserving the Turbo Wastegate Flap
To prevent the wastegate flap from binding/jamming, spray a corrosion-protection agent onto
the shaft and bush.
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.
