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 Marine Power Products, 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.
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 and ignition 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.
Any time the intake or exhaust openings are exposed during service they should be covered to protect against accidental
entrance of foreign material into the cylinders which could cause extensive internal damage when the engine is started.
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.
