PROPULSION SYSTEM

1.1 General

The Monterey 400 Sport Yacht is designed to be
powered with Volvo's Inboard Power System (IPS)
and diesel engines. Volvo provides an owner's in-
formation manual with its product. It is important
that you read the manual(s) very carefully and
become familiar with the proper care and opera-
tion of the engine and drive system. A warranty
registration card has been furnished with each new
engine and can be located in the engine owner's
manual. All information requested on this card
should be filled out completely by the dealer and
purchaser and then returned to the respective
engine manufacturer as soon as possible.
CERTAIN MOVING PARTS ARE EXPOSED AND CAN
PROVE DANGEROUS TO SOMEONE UNFAMILIAR
WITH THE OPERATION AND FUNCTION OF THE
EQUIPMENT. DO NOT ATTEMPT TO SERVICE ANY
ENGINE OR DRIVE COMPONENT WITHOUT BEING
TOTALLY FAMILIAR WITH THE SAFE AND PROPER
SERVICE PROCEDURES.

1.2 Drive Systems

The inboard engines are mounted in the stern and
coupled to the IPS drives which do all shifting,
steering, and propulsion functions. The IPS drives
are supplied by Volvo and have specific lubrication
and maintenance requirements.
Proper engine alignment is very important. This
was done by the factory when the engines were
installed and should not be required again unless
the an engine is removed, a drive is damaged or
an engine mount becomes loose. If you experi-
ence excessive vibrations or suspect that the
engine is out of alignment, please contact your
Monterey dealer.
Marine growth and galvanic corrosion is a con-
cern if the boat is to be kept in the water. Marine
growth occurs when components are left in the
water for extended periods and can cause poor
performance or permanent damage to the exposed
components. The type of growth and how quickly
it occurs is relative to the water conditions in your
boating area. Water temperature, pollution, cur-
rent, etc. can have an effect on marine growth.
If the boat is to be left in saltwater, the hull and
drive system must be protected with antifouling
Volvo Diesel Engine and IPS Drive System
paint. It is extremely important that the proper
antifouling paint is used on each component.
Contact your Monterey dealer for information on
the proper paint to use in your area.
Galvanic corrosion is the corrosion process oc-
curring when different metals are submerged in
an electrolyte. Sea water is an electrolyte and
submerged IPS components must be properly
protected. The drives are connected to sacrificial
anodes, mounted on the transom below the wa-
terline, that prevent galvanic corrosion problems.
The anodes must be monitored and replaced as
necessary. For recommendations regarding cor-
rosion protection for the IPS system, please refer
to the engine owner's manual.
MANY ANTIFOULING PAINTS DESIGNED FOR BOAT
HULLS CAN CAUSE SEVERE DAMAGE TO THE IPS
DRIVE IF THEY ARE NOT PROPERLY APPLIED.
PROPER PAINT SELECTION AND PROCEDURES
MUST BE FOLLOWED WHEN PAINTING THE IPS
DRIVE. CONTACT YOUR MONTEREY DEALER OR
ENGINE MANUFACTURER FOR INFORMATION ON
THE PROPER PAINTING PROCEDURES.

1.3 Engine Exhaust System

Inboard engines use the exhaust system to expel
exhaust gases and cooling water. Engine exhaust
exits the bottom of the boat through the IPS drive
system. The system consists of engine exhaust
manifolds, exhaust hoses and the IPS drive.
