¾ Service
Maintenance
The good functioning and the efficiency of the mechanical components mainly depend on a
constant and correct maintenance.
TAKING VISION OF THE ENTIRE MANUAL allows to properly perform the
operations of ordinary and extraordinary maintenance.
The lack of the recommended operations can compromise the lifetime and the integrity of the
transmission and bring to failure or injury to the operator.
In the event of breakdown or anomaly, the prompt reaction from the specialized personnel will
guarantee a higher lifetime of the assembly, preventing further damage in the years.
GENERAL SAFETY RECOMMENDATIONS
IMPORTANT:
Before starting any operation, read this paragraph carefully.
Safety precautions
The correct use and the correct repair of the assembly and its components are very important for
security and reliability. The recommended procedures, that are listed on this service manual, have
been tested as operative ways to act. Strictly follow each procedure making use both of writings
and illustrations.
Some of these procedures show the usage of pertinent tools designed to perform every operation
clearly and correctly.
Some specific tools must be used, where necessary, to perform some proper operations. It is
impossible to manage every working procedure or all the possible methods with their own risks,
therefore whoever uses not recommended tools must be aware that the safety of the operator and
the boat will be endangered.

Recall icons
= DANGEROUS OPERATIONS FOR THE SAFETY OF THE OPERATOR
= WEAR PROTECTIVE GLOVES FOR HIGH TEMPERATURE
= OPERATION REQUIRING PARTICULAR ATTENTION AND PRECISION FROM
THE OPERATOR
= OPERATION DAMAGING THE COMPONENT OR PRODUCT IF NOT
PERFORMED CORRECTLY
Repair
The procedure for assembly / disassembly of the transmission allows to perform the complete
overhaul of the group and is assisted with photos, for a complete and safe guide for each
operation.
It is assumed that the transmission has been removed from the vessel. The deep knowledge of
the assembly allows the correct estimate of the kind of procedure to be followed, which may only
require the disassemble of a few components, operating on a part of the transmission only.
