Notice to Users of This Manual
This service manual has been written and published by the Service Department of Mercury
Marine to aid our dealers’ mechanics and company service personnel when servicing the
products described herein.
It is assumed that these personnel are familiar with marine product servicing procedures.
Furthermore, it is assumed that they have been trained in the recommended service
procedures of Mercury MerCruiser product, including the use of mechanics’ common hand
tools and the special Mercury Marine or recommended tools from other suppliers.
We could not possibly know of and advise the marine trade of all conceivable procedures
and of the possible hazards and/or results of each method. Therefore, anyone who uses
a service procedure and/or tool, which is not recommended by the manufacturer, first must
completely satisfy himself that neither his nor the products safety will be endangered.
All information, illustrations and specifications contained in this manual are based on the
latest product information available at the time of publication. As required, revisions to this
manual will be sent to all dealers contracted by us to sell and/or service these products.
We reserve the right to make changes to this manual without prior notification.
Refer to dealer service bulletins, operation maintenance and warranty manuals and
installation manuals for other pertinent information concerning the products described in
this manual.
It should be kept in mind, while working on the product, that the electrical system is capable
of violent and damaging short circuits or severe electrical shocks. When performing any
work where electrical terminals could possibly be grounded or touched by the mechanic,
the battery cables should be disconnected at the battery.
Any time the intake or exhaust openings are exposed during service they should be covered
to protect against accidental entrance of foreign material which could enter the cylinders and
cause extensive internal damage when the engine is started.
It is important to note, during any maintenance procedure replacement fasteners must have
the same measurements and strength as those removed. Numbers on the heads of the
metric bolts and on the surfaces of metric nuts indicate their strength. American bolts use
radial lines for this purpose, while most American nuts do not have strength markings.
Mismatched or incorrect fasteners can result in damage or malfunction, or possibly personal
injury. Therefore, fasteners removed should be saved for reuse in the same locations
whenever possible. Where the fasteners are not satisfactory for re-use, care should be
taken to select a replacement that matches the original.

Engine Mechanical Components
Many of the engine mechanical components are designed for marine applications. Unlike
automotive engines, marine engines are subjected to extended periods of heavy load
and wide open throttle operation and, therefore, require heavy-duty components. Special
marine engine parts have design and manufacturing specifications that are required to
provide long life and dependable performance. Marine engine parts also must be able to
resist the corrosive action of salt or brackish water that will rust or corrode standard
automotive parts within a short period of time.
Failure to use recommended Mercury / Quicksilver service replacement parts can result in
poor engine performance and/or durability, rapid corrosion of parts subjected to salt
water and possibly complete failure of the engine.
Replacement Parts
Use of parts other than the recommended service replacement parts, will void the warranty
on those parts that are damaged as a result.
Electrical and fuel system components on Mercury MerCruiser Engines and Stern
Drives are designed and manufactured to comply with U.S. Coast Guard Rules
and Regulations to minimize risks of fire or explosion.
Use of replacement electrical or fuel system components, which do not comply to
these rules and regulations, could result in a fire or explosion hazard and should
be avoided.
When servicing the electrical and fuel systems, it is extremely important that all
components are properly installed and tightened. If not, any electrical component
opening would permit sparks to ignite fuel vapors from fuel system leaks, if they
existed.
