Section 5 - 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, 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 Mercury Diesel authorized repair facility for service aids.

Dealer Responsibilities

It is the dealer's responsibility to provide predelivery inspection and preparation:
• Before delivery, making certain that the Mercury 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.
• Completing the warranty registration and immediately submitting it to Mercury Marine via MercNET, e‑mail, or mail. All
power packages must be registered for warranty purposes.
Do‑It‑Yourself Maintenance Suggestions
Mercury power packages are highly technical, complex pieces of machinery. Only qualified personnel using the proper tools
should attempt major repair.
• Your safety is our concern. Always read and understand the Cautions, Warnings, Important Notices, and Notes.
• Do not attempt repairs unless specifically trained in that procedure.
• Reference the correct service manual for the product. Do not attempt repairs unless qualified.
• Special tools and equipment are required to perform certain repairs. Failure to use the correct special tools and equipment
can result in severe damage to the product.
• Always have a Mercury Diesel authorized repair facility service your power package and do periodic maintenance
inspections to help provide safe and trouble‑free boating.

Inspection

Inspect your power package often and at regular intervals to help maintain its top operating performance and correct potential
problems before they occur. The entire power package should be checked carefully, including all accessible engine parts.
1. Check for loose, damaged, or missing parts, hoses, and clamps; tighten or replace as necessary.
2. Check electrical connections and leads for damage.
3. Remove and inspect the propellers. If badly nicked, bent, or cracked, contact your Mercury Diesel authorized repair facility.
4. Repair nicks and corrosion damage on power package exterior finish. Contact your Mercury Diesel authorized repair
facility.
