PROPULSION SYSTEM
3.1 General
Your boat is designed to be powered with single or
twin inboard engines and outdrive systems. Each
manufacturer of the various inboard/outboard
drive systems provides an owner’s information
manual with its product. It is important that you
read the manual(s) very carefully and become
familiar with the proper care and operation 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
out completely by the dealer and purchaser and
then returned to the respective engine manufac-
turer 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
TOTALLY FAMILIAR WITH THE SAFE AND PROPER SERVICE
PROCEDURES.
3.2 Drive Systems
The inboard engine is mounted in the stern and
coupled to a transom mounted outdrive which
does all shifting, steering, and propulsion func-
tions. The outdrive is supplied by the engine
maintenance requirements. Twin engine boats will
be equipped with two engines and two outdrives.
Proper engine alignment is very important. This
was done by the factory when the engine was
installed and should be checked once per season
with Volvo engines and once every three years
with Mercruiser engines thereafter. If you expe-
rience 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 ex-
posed components. The type of growth and how
quickly it occurs is relative to the water conditions
in your boating area. Water temperature, pollu-
tion, current, etc. can have an effect on marine
growth. If the boat is to be left in saltwater, the
hull and outdrive must be protected with antifoul-
ing paint. It is extremely important that the prop-
er 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. Seawater is an electrolyte and
submerged engine components must be properly
anodes to prevent galvanic corrosion problems.
The anodes must be monitored and replaced as
necessary.
On some outdrives, the standard anode may not
provide an acceptable level of protection when
a drive is used in fresh water and a magnesium
anode must be used. A magnesium anode, when
used for combined operation in both fresh and
saltwater, or water with a low salt content, will
deteriorate quicker and must therefore be replaced
