1. INTRODUCTION
The Owner’s manual, which you received together with a boat, will help you operate your
CORSIVA 650 TENDER motorboat safely and appropriately so you may use it with pleasure.
Manual contains the description of the boat, its equipment and installation systems as well
as practical information about its use and maintenance.
Read the information carefully before using the boat.
This Owner's Manual is not a detailed guide of the boat’s maintenance or troubleshooting. In
case of difficulties, contact your manufacturer or its dealer.
Always employ trained and qualified people for maintenance or repairs.
Repairs which may impact on safety features of the yacht should be evaluated, carried out
and documented by qualified people.
The boat manufacturer is not responsible for the modifications made without its consent
therefore any modification of the boat repeals the boat’s warranty.
Always keep your boat in a good condition and take into account the boat’s deterioration
that will follow in time as a result of intensive use or improper handling of the boat.
Each boat, regardless of how it is strong, can be severely damaged if is not properly used.
Always adjust the speed and direction of the boat to the conditions on the water.
This owner’s manual owner is not a course of safety yachting or sailing skills.
If this is your first boat or if you change the boat’s type (to which you do not know) for your
own comfort and safety, make sure that you got the experience in leading the boat and
operating it. Your dealer, a national sailing federation or boat clubs will be pleased to
provide you all information on local marine schools or qualified instructors.
With wishes of successful cruises,

3. GENERAL SAFTY RULES
3.1. Safety
Even if all was planned the safety of the sailing remains heavily dependent on the weather,
sea conditions, the experience and knowledge of the crew.
Always check the weather forecast before leaving and see that the circumstances should be
expected to the boat’s construction category.
Before you prepare your boat for sailing, check local water sailing legislations under which
you have to obey.
Check the restrictions for swimming; speed limit restrictions and outboard noise and fumes
reduction.
Stimulants
Never sail under the influence of alcohol or drugs.
The combination of noise, vibration, sun, wind and water movement causes fatigue. The
effects of alcohol on the water are worse than on land.
3.2. Passengers on board
During boarding the passengers, stop the engine.
Moving the engine level to the neutral position is not sufficient.
The boat’s helmsman is responsible for passengers and cargo.
Do not overload the boat.
The boat is evaluated relatively to the maximum of load and capacity.
If in doubt, contact your dealer or the yacht manufacturer.
WARNING
Stimulants and sailing do not go together. Operating a boat while being under
the influence of alcohol or other forbidden substances is illegal and dangerous.
Weakening eyesight or assessment of the situation can lead to a disaster.
WARNING
The helmsman cannot allow anyone to sit on the parts of the boat not intended
for it. In particular the boat edges, seatbacks, transom, bow, or anywhere
where an unexpected acceleration or sudden stop will cause a person fall
overboard.

3.3. Life-saving equipment
There should be a boat type and weather conditions’ appropriate safety equipment on the
boat (life jackets, safety harnesses, etc.) In some countries equipment is indicated and
required by the local law.
Carefully read the manual of a life raft.
The crew should be familiar with the use of all safety equipment and emergency
maneuvering (man overboard, towing, etc.). Sailing schools and clubs regularly organize
training sessions.
All persons should wear appropriate rescue measures (lifejackets / buoyancy aids), while
they are on board. Please note that in some countries there is a legal requirement to wear a
permanent rescue equipment.
WARNING
Always turn off the engine when the boat is located near people in the water.
Even at low engine power, the screw can cause serious injuries.
WARNING
Read carefully the instructions placed on the life jackets label and follow them.
Checking the condition of life jackets, make sure it fits the body.
Try vest before you fall into the water.
WARNING
It is important for children and non-swimmers to wear life jackets. Children
who cannot swim require special instruction on how to use lifejackets.

CORSIVA YACHTING
10
Remember:
✔any change in arrangement of the masses on the side (eg. the addition of a fishing tower,
a change in the engine etc.) can significantly affect the stability, trim and behavior of the
boat,
✔amount of bilge water should be as small as possible,
✔stability is decreased by adding any high-mounted weight,
✔gaps in bad weather, lockers, doorways should be closed to minimize the risk of flooding,
✔stability may be reduced when towing,
✔air chambers can’t be pierced,
✔breaking waves are a serious threat to stability.
DANGER
Information about stability and freeboard, floatation and buoyancy is fulfilled
only when:
✔The weight of empty boat (with engine) does not exceed 1140 kg,
✔The maximum power of engine does not exceed 66, kW
CAUTION
The fulfillment of the stability requirement and freeboard as well as buoyancy
and flotation does not guarantee the boat will not overturn or sink if all criteria
of exploiting the boat are not kept.
The helmsman of boat is responsible for complying to proper sea practice in
reference to safety of crew and boat.

7. ENGINE
The manufacturer leaves the derived hoses in engine
compartment so its dealer or customer could attache the
engine in the future. (see the photo).
To drive the boat, you should apply the motor with the
maximum power recommended by manufacturer of the
boat – max. 66, kW (90 HP). The engine might be with a
long column.
The engine should be in such a position so it wouldn’t allow the screw to cavitate. Cavitation
of screw reduces the engine efficiency and and in consequence the towing power. The
excessive diving of engine introduces additional resistance of hull, which reduces the sailing
speed.
CAUTION
Always follow the rules of maintenance and service included in the owner’s
book by the engine manufacturer, in particular:
✔apply the suitable fuel or the mixture with the proper proportion of oil and
the fuel,
✔check the level of fuel tank before starting the engine,
✔after starting the engine check if cooling water is carried away through the
exhaust,
✔do not make any noise or waves in the harbor, do not exceed the speed
limit,
✔follow the manufacturer’s instructions while usage, maintenance and winter
storage of the yacht,
✔do not use the engine with power exceeding the acceptable power of the
boat.
CAUTION
Carry out the inspection of driving screw after its intensive exploitation. It will
prevent its damage, let you keep the screw in good state and lengthen the
vitality of engine.
Sailing to the shallow shore especially from a stern side can lead to damage or
loss of the lower part of the engine.

7.1. Engine compartment
Hiding the engine in compartment makes boarding or leaving from the deck easy while the
boat is stern moored. Additionally, hidden engine reduces the noise, which a running engine
produces, improving for crew comfort during cruises.
The engine compartment of the boat is a special place and special attention should be
devoted to it due to the gravitational excretion of exhaust gases.
7.1.1. Gravitational ventilation
DANGER
NEVER cover the ventilation grills.
NEVER modify the ventilation system of the engine compartment of the boat.
Ventilation grates are placed on
both sides of a engine
compartment as well as its
cover. They are for supplying
fresh air and shedding outside
exceeded heat and petrol fumes.

CORSIVA YACHTING
14
7.1.2. Mechanical ventilation
The exhaust gases from the
engine exhaust are
discharged through a hose,
which on the one side is
connected to the engine, and
on the other to the end of
exhaust, which exhausts
them out of the boat.
The exhaust end is obligatory
mounted on the back wall of
the stern.
Apart from the gravitational ventilation
system there is a mechanical exhaust
ventilation system which removes an excess
of exhaust gases to the atmosphere.
Suction of an exhaust system is on the left
side of the engine compartment.
DANGER
The threat of life loss.
NEVER INTERFERE IN EXPULSION OF EXHAUST SYSTEM!
Any interference with exhaust system brings unsealing the system and
therefore the risk of exhaust gas poisoning.
DANGER
The exhaust fan should be turned on before starting the engine and should
work at all times when engine is running.
