Section 4 - Maintenance

Owner and 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 a Mercury Diesel–authorized repair facility for a periodic checkup.
Normal maintenance service and replacement parts are the responsibility of the owner or operator and are not covered by 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 Mercury Diesel–authorized repair facility for service aids.

Dealer Responsibilities

Below is a list of Mercury Diesel dealer predelivery inspection and preparation responsibilities:
• Verify that the power package is in proper operating condition.
• Make any necessary adjustments for maximum efficiency.
• Explain and demonstrate the operation of the power package and the boat.
• Provide a copy of the Predelivery Inspection Checklist.
• Fill out the warranty registration card completely and mail it to the factory immediately upon sale of the new product. All
power packages must be registered for warranty purposes.

Maintenance

Neglect or improper maintenance, repairs, or inspections of the power package can result in product damage or serious injury
or death. Perform all procedures as described in this manual. If you are not familiar with proper maintenance or service
procedures, consign the work to an authorized Mercury Marine dealer.
Accidental engine starting can cause serious injury or death. Remove the key from the ignition switch and engage the lanyard
stop or E‑stop switch to prevent the engine from starting when performing service or maintenance on the power package.
Engine components and fluids are hot and can cause serious injury or death. Allow the engine to cool before removing any
components or opening any fluid hoses.
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 Maintenance Schedule for a complete listing of all scheduled maintenance to be performed. Some
tasks can be done by the owner or operator, while others should be performed by an authorized Mercury Diesel repair facility.
Before attempting maintenance or repair procedures not covered in this manual, we recommended that you purchase the
appropriate Mercury Diesel service manual and read it thoroughly.
Before performing any maintenance on your Mercury Diesel engine:
• Protect yourself with suitable work clothing and personal protection equipment.
• Stop the engine, remove the ignition key, and press the emergency stop switch.
• Move the throttle to the neutral position.
• Allow the engine to cool.
• Ventilate the engine compartment for at least five minutes before beginning work.
• Disconnect the battery, if servicing any electrical components. Always disconnect the negative (–) lead first and reconnect
it last.
