particular service or operation that may be hazardous if performed incorrectly or carelessly.

to these special instructions when performing the service, plus common sense operation,
are major accident prevention measures.

This installation manual has been written and published by Mercury Marine to aid the boat
manufacturer involved in the application and installation of the products described herein.
It is assumed that these personnel are familiar with the installation procedures of these
products, or like or similar products manufactured and marketed by Mercury Marine. That
they have been trained in the recommended installation procedures of these products which
includes the use of mechanics’ common hand tools and the special Mercury Marine or
recommended tools from other suppliers.
It is the responsibility of the OEM to select the appropriate engine/transom/drive package
(including the correct gear ratio and propeller) for a given boat. Making an appropriate
selection requires knowledge of the boat (weight, length, hull design, intended use and duty
cycle, desired speed) that is uniquely in the possession of the OEM. While Mercury employs
people capable of assisting the OEM on such issues, the final decision rests with the OEM.
Mercury recommends that any new or unique hull/power package combination be
thoroughly water tested prior to sale, to verify (among other things) that the boat performs
as desired, and that the engine runs in the appropriate rpm range.
We could not possibly know of and advise the marine trade of all conceivable procedures
by which an installation might be performed, and of the possible hazards and/or results of
each method. We have not undertaken any such wide evaluation. Therefore, anyone who
uses an installation procedure and/or tool, which is not recommended by the manufacturer,
first must completely satisfy himself that neither his nor the product’s safety will be
endangered by the installation procedure selected.
It is recommended that a Mercury Marine Sales Application Engineer (SAE) be contacted
for assistance if specific application or installation problems are encountered.
All information, illustrations, and specifications contained in this manual are based on the
latest product information available at time of publication. As required, revisions to this
manual will be sent to all OEM boat companies.
