General Information

Owner/Operator Responsibilities

It is the operator's responsibility to perform all safety checks, to ensure that all lubrication and maintenance instructions are
complied with for safe operation and to return the unit to an authorized Mercury MerCruiser dealer for a periodic checkup.
Normal maintenance service and replacement parts are the responsibility of the owner/operator and as such, are not
considered defects in workmanship or material within the terms of the warranty. Individual operating habits and usage
contribute to the need for maintenance service.
Proper maintenance and care of your power package will ensure optimum performance and dependability and will keep your
overall operating expenses at a minimum. See your authorized Mercury MerCruiser dealer for service aids.

Dealer Responsibilities

In general, a dealer's responsibilities to the customer include predelivery inspection and preparation such as:
• Ensure that the boat is properly equipped.
• Prior to delivery, make certain that the Mercury MerCruiser power package and other equipment are in proper operating
condition.
• Make all necessary adjustments for maximum efficiency.
• Familiarize the customer with the onboard equipment.
• Explain and demonstrate the operation of the power package and boat.
• Provide you with a copy of a Predelivery Inspection Checklist.
• Your selling dealer should fill out the Warranty Registration Card completely and mail it to the factory immediately upon
sale of the new product.

Maintenance

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 engine starting. Always disconnect the battery cables from the
battery before maintaining, servicing, installing, or removing engine or drive components.
Fuel vapors trapped in the engine compartment may be an irritant, cause difficulty breathing, or may ignite resulting in a fire
or explosion. Always ventilate the engine compartment before servicing the power package.
IMPORTANT: Refer to the maintenance schedule for the complete listing of all scheduled maintenance to be performed. A
repair shop or person of the owner's choosing may maintain, replace, or repair emission control devices and systems. Certain
other items should be performed only by an authorized Mercury MerCruiser dealer. Before attempting maintenance or repair
procedures not covered in this manual, we recommend that you purchase a Mercury MerCruiser service manual and read it
thoroughly.
NOTE: Maintenance points are color‑coded for ease of identification.

Do‑It‑Yourself Maintenance Suggestions
Present day marine equipment, such as your Mercury MerCruiser power package, are highly technical pieces of machinery.
Electronic ignition and special fuel delivery systems provide greater fuel economies, but also are more complex for the
untrained mechanic.
If you are one of those persons who likes to do it yourself, here are some suggestions for you.
• Do not attempt any repairs unless you are aware of the Cautions, Warnings, and procedures required. Your safety is our
concern.
• If you attempt to service the product yourself, we suggest you order the service manual for that model. The service manual
outlines the correct procedures to follow. It is written for the trained mechanic, so there may be procedures you don't
understand. Do not attempt repairs if you do not understand the procedures.
