NO PASSENGERS ON BOARD WHILE LIFTING.
WARNING!!!
ALL EQUIPMENT MUST BE UNLOADED FROM THE BOAT FOR LIFTING
OR DAVIT HANDLING.
BEFORE LAUNCHING THE BOAT, OPEN THE AFT DRAIN HOLE TO DRAIN
ANY RAINWATER FROM THE BOTTOM OF THE BILGE (CLOSE THE
DRAIN HOLE AGAIN BEFORE LAUNCHING).

BUOYANCY CHAMBER –Installing the buoyancy chamber on the hull
BUOYANCY CHAMBER
BUOYANCY CHAMBER
Your boat’s buoyancy chamber is made from STRONGAN DUOTEX®1100 Decitex, 1000 gr/m² or
NEOPRNE CSM-CR 1100 Decitex, 1050 gr/m².
The maintenance recommendations are specified in VOLUME I of the owner's manual.

BUOYANCY CHAMBER - INFLATING THE BUOYANCY CHAMBER
PRESSURE GAUGE
DANGER!!!
NEVER USE A COMPRESSOR OR COMPRESSED AIR CYLINDER.
INFLATION
1º/ Place all valves in inflation position.
2º/ Fit the adaptor that matches the diameter of the "easy-
push" valve to the inflation tube tip.
3º/ Attach the hose connector to the inflation pump inflation
valve.
To properly inflate your tube, the inflator needs to be properly
placed on the ground.
The tube will inflate quickly if the inflator is operated smoothly
and unhurriedly.
4./ Inflate the tube starting with the first compartment (a) from the bow (front), until a pressure of
200 mb is reached.
5./ Then inflate the compartments (b) in the middle, until a pressure of 220 mb is reached, as read
on the pressure gauge left on the first compartment.
6./ Then inflate the aft compartments (c) to a pressure of 240 mb, still leaving the pressure gauge in
the same location. The partitions (1) enable the pressure between each chamber to balance out.
7º/ Inflation is completed: screw on the inflation valve plugs.

Page 16 / 33
614225 - Edition 1
BUOYANCY CHAMBER –PRESSURE
NOTE: Observing a slight air loss before screwing the valve cap on is perfectly normal.
Only the plugs provide final airtightness.
PRESSURE
The tube has 5 compartments. Each one should be at a pressure of 240 mb / 3.4 PSI.
It is the buoyancy chamber's correct pressure.
The ambient temperature of the air or the
Ambient temperature
Pressure inside the
buoyancy chamber
water proportionally influences the
+1°C
+4 mb / 0.06 PSI
internal pressure of the buoyancy chamber.
-1°C
-4 mb / 0.06 PSI
It is therefore important to be able to anticipate changes.
Check and adjust the pressure of inflatable compartments (by inflating or deflating) depending on
the temperature (particularly when temperature variations are high between the morning and
evening in particularly hot regions) and check that the pressure does not exceed the recommended
pressure zone (from 220 to 270 mb).
RISK OF PRESSURE LOSS
Example:
Your boat is exposed to bright sunlight on the beach (temperature = 50°C) at the recommended
pressure level (240 mb/3.4 PSI). When you put it in the water (temperature = 20°C), the temperature
of the inflatable compartments and the pressure inside them will fall in step (by up to 120 mb) and
YOU WILL NEED TO REFLATE to regain the millibars lost due to the difference in temperature between
the ambient air and water.
It is normal to observe a drop in pressure at the end of the day when the outdoor temperature drops.

BUOYANCY CHAMBER –PRESSURE
RISK OF OVERPRESSURE
Example:
Your boat is inflated to its recommended pressure (240 mb/3.4 PSI) at the start or the end of the day
(low outside temperature = 10°C). During the day, your boat is exposed to bright sunlight on the beach
or on the deck of a yacht (temperature = 50°C). Temperature inside the inflatable compartments will
increase (up to 70°C) especially with a dark colour buoyancy chamber, causing the pressure to double
(480 mb). YOU WILL NEED TO DEFLATE to return to the recommended pressure.
DANGER!!!
IF YOUR BOAT IS OVERINFLATED, THE PRESSURE WILL ABNORMALLY
WEAR THE INFLATABLE STRUCTURE WHICH MAY LEAD TO A BREACH
OF THE ASSEMBLY.
SHOULD AN OVERPRESSURE OCCUR
Release air by pressing on the valve knob

PROPULSION SYSTEM
PROPULSION SYSTEM
General
Comply with the ZODIAC and the TORQEEDO recommendations for the assembly, use and servicing of
the engine and the battery.
To get the best out of your boat, please consult your dealer.
The engine bolts must be fitted through the transom using a screw hole sealing procedure (e.g: using
Sikaflex sealant).
ENGINE RIGGING
As all of the electrical system is already installed, the engine just needs to be connected to the boat.
The engine power cables are designed to be routed through the engine duct (1) and exit through the
bench via the cable gland sleeve (2). Finally, complete by connecting the cables to the isolator switch
(3) ensuring the polarities are respected

USING YOUR BOAT
USING YOUR BOAT
How to drive your boat
Before starting, refer to the Owner's Manual Volume I.
NOTE: Check that the buoyancy chamber is correctly inflated.

2
Isolator switch set to "ON", powered up
Put on and connect the circuit breaker*
3
4
Throttle lever in neutral
Move the engine starter to position (2)
* If the coxswain falls overboard, immediately stopping the engine considerably reduces the risks of
serious or fatal injury caused by being run over by the boat. Always couple the two ends of the
emergency circuit breaker correctly.
DANGER!!!
- TURN OFF THE ENGINE IMMEDIATELY AS SOON AS A SWIMMER COMES
CLOSE TO THE BOAT. THEY RISK BEING SERIOUSLY INJURED BY A ROTATING
PROPELLER.
WARNING!!!
WHEN UNDERWAY, KEEP ALL LOCKERS, DECK HATCHES AND TANK ACCESS
HATCH CLOSED.
BREAKING WAVES CAN BE A SIGNIFICANT DANGER FOR STABILITY AND
CAUSE FLOODING.
- SHOULD A DECK HATCH SEAL BECOME DAMAGED, PLEASE CONTACT YOUR
DEALER TO ENSURE REPLACEMENT AS SOON AS POSSIBLE.
- AVOID ABRUPT MANOEUVRES AT FULL SPEED. REDUCE SPEED IN WAVES
FOR THE COMFORT AND SAFETY OF PASSENGERS.
