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.
Weber engine service manual.
Buoyancy Tube
Prior to storing over the winter periods the buoyancy tubes must be deflated and hosed down
End of
with fresh water, removing any small stones and weed from luffing track, then allowed to dry.
year
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. Remove the drain hose connected to the base of the heat exchanger at hose
clip and purge residual raw water, OR 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 or similar white grease to battery isolator switch, upholstery press studs and
telescopic all-round white light. Use maintenance spray on key switch. Apply a proprietary
corrosion guard to engine, electrical connections, under helm and around jet pump area.
