Preventive Maintenance
To achieve maximum operating safety and service life, it is vital to maintain the en-
gine and its fittings in accordance with the maintenance schedule. This gives instruc-
tions on when and how to carry out maintenance. Always consult an authorized Volvo
Penta service dealer, who will have the equipment and trained staff to help you.
For boats used for commercial purposes, there is also a program of preventive main-
tenance known as “Condition Test”, which is part of the “Cost Control Program”. This
program is carried out every 6 months, and every other time in accordance with an
extended program.
A maintenance program well carried out gives better operating economy and fewer
unplanned periods of non-operation.
