Introduction:
This service manual is divided into sections concerning various systems and assemblies. Refer to the Table Of
Contents to locate the section covering the system or assembly requiring service. Each section title page has an
additional listing that will describe the section’s contents in more detail. Be sure to read Safety Information on page
i at the beginning of this manual, and pay special attention to all safety warnings as they appear throughout the
text. Since models are subject to change at any time, some photos may not depict actual product.
Good Service Practice
Service required for stern drives is generally one of
three kinds:
• Normal care and maintenance – which
includes putting a new stern drive into operation,
storing engines, lubrication, and care under special
operating conditions such as salt water and
cold weather.
• Operating malfunctions – due to improper
engine or drive mounting, propeller condition or
size, boat condition, or the malfunction of some
part of the engine. This includes engine servicing
procedures to keep the engine in prime operating
condition.
• Complete disassembly and overhaul – such
as major service or rebuilding a unit.
It is important to determine before disassembly just
what the trouble is and how to correct it quickly, with
minimum expense to the owner.
When repairing an assembly, the most reliable way to
ensure a good job is to do a complete overhaul on
that assembly, rather than just to replace the bad
part. Wear not readily apparent on other parts could
cause malfunction soon after the repair job. Repair
kits and seal kits contain all the parts needed to
ensure a complete repair, to eliminate guesswork,
and to save time.
Repair time can also be minimized by the use of special
tools. Volvo Penta special tools are designed to
perform service procedures unique to the product
that cannot be completed using tools from other
sources. They also speed repair work to help achieve
service flat rate times. In some cases, the use of substitute
tools can damage the part.
