9 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 AQUANAMI engine service
manual.
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 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 Jettender 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.
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.
