This 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. We reserve the right to make changes to this
manual without prior notification.
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 MotorGuide products, including the use of mechanics' common
hand tools and the special MotorGuide 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, when using a service procedure and/or tool that is not recommended by the manufacturer,
be completely satisfied that neither your personal or product safety is 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.
Refer to dealer service bulletins, operation maintenance and warranty manuals, and installation manuals for other pertinent
information concerning the products described in this manual.
Precautions
It should be kept in mind, while working on the product, that the electrical systems are 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.
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 reuse, care should be taken to
select a replacement that matches the original.
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.
Performing service or maintenance without first disconnecting the battery can cause product damage, personal injury, or
death due to fire, explosion, electrical shock, or unexpected motor starting. Always disconnect the battery cables from the
battery before maintaining, servicing, installing, or removing motor components.
