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

In general, a dealer's responsibilities to the customer include predelivery inspection and preparation:
• Before delivery, making certain that the Mercury Diesel power package is in proper operating condition.
• Making all necessary adjustments for maximum efficiency.
• Explaining and demonstrating the operation of the power package and the boat.
• Providing a copy of the Predelivery Inspection Checklist.
• Filling out the Warranty Registration Card completely and mailing it to the factory immediately upon sale of the new
product. All power packages must be registered for warranty purposes.

Cleaning Care Recommendation

Do Not Use Caustic Cleaning Chemicals

IMPORTANT: Do not use caustic cleaning chemicals on any part of the Mercury Diesel power package. Some cleaning
products contain strong caustic agents. For example, some hull cleaners contain hydrochloric acid. These cleaners can
degrade some of the components they contact, including critical steering fasteners.
Damage to steering fasteners may not be obvious during visual inspection, and this damage may lead to catastrophic failure.
Some caustic cleaning chemicals may cause or accelerate corrosion. Exercise caution when using cleaning chemicals around
the power package, and follow the recommendations on the packaging of the cleaning product.

Cleaning Gauges

IMPORTANT: Never use high‑pressure water to clean gauges.
Routine cleaning of the gauges is recommended to prevent a buildup of salt and other environmental debris. Crystalized salt
can scratch the gauge display lens when using a dry or damp cloth. Ensure that the cloth has a sufficient amount of fresh water
to dissolve and remove salt or mineral deposits. Do not apply aggressive pressure on the display lens while cleaning.
When water marks cannot be removed with a damp cloth, mix a 50/50 solution of warm water and isopropyl alcohol to clean the
display lens. Do not use acetone, mineral spirits, turpentine type solvents, or ammonia based cleaning products. The use of
strong solvents or detergents may damage the coating, the plastics, or the rubber keys on the gauges. If the gauge has a sun
cover available, it is recommended that the cover be installed when the unit is not in use to prevent UV damage to the plastic
bezels and rubber keys.

Cleaning Remote Controls

IMPORTANT: Never use high‑pressure water to clean remote controls.
Routine cleaning of the remote control external surfaces is recommended to prevent a buildup of salt and other environmental
debris. Use a cloth towel which has a sufficient amount of fresh water to dissolve and remove salt or mineral deposits.
When water marks cannot be removed with a damp cloth, mix a 50/50 solution of warm water and isopropyl alcohol to clean the
remote control. Do not use acetone, mineral spirits, turpentine type solvents, or ammonia based cleaning products. The use of
strong solvents or detergents may damage the coating, the plastics, or the rubber components on the remote control.

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.
