Warranty Information
Warranty Registration United States and Canada
1. To be eligible for warranty coverage, the product must be registered with Mercury Marine. At the time of sale, the dealer
should complete the warranty registration and immediately submit it to Mercury Marine via MercNET, E‑mail, or mail. Upon
receipt of this warranty registration, Mercury Marine will record the registration.
2. Warranty coverage is not effective until your product is registered with Mercury Marine.
3. You may change your address at any time, including at time of warranty claim, by calling Mercury Marine or sending a
letter or fax with your name, old address, new address, and engine serial number to Mercury Marine’s Warranty
Registration Department. Your dealer can also process this change of information.

NOTE: Registration lists must be maintained by Mercury Marine and any dealer on marine products sold in the United
States, should a safety recall notification under the Federal Safety Act be required.
Warranty Registration—Outside the United States and Canada
1. It is important that your selling dealer fills out the Warranty Registration Card completely and mails it to the distributor or
Marine Power Service Center responsible for administering the warranty registration and claim program for your area.
2. The Warranty Registration Card identifies your name and address, product model and serial numbers, date of sale, type of
use and the selling distributor's and dealer's code number, name and address. The distributor or dealer also certifies that
you are the original purchaser and user of the product.
3. A copy of the Warranty Registration Card, designated as the Purchaser's Copy, must be given to you immediately after the
card has been completely filled out by the selling distributor or dealer. This card represents your factory registration
identification, and should be retained by you for future use when required. Should you ever require warranty service on this
product, your dealer may ask you for the Warranty Registration Card to verify date of purchase and to use the information
on the card to prepare the warranty claim forms.
4. In some countries, the Marine Power Service Center will issue you a permanent (plastic) Warranty Registration Card within
30 days after receiving the Factory Copy of the Warranty Registration Card from your distributor or dealer. If you receive a
plastic Warranty Registration Card, you may discard the Purchaser's Copy that you received from the distributor or dealer
when you purchased the product. Ask your distributor or dealer if this plastic card program applies to you.
5. For further information concerning the Warranty Registration Card and its relationship to Warranty Claim processing, refer
to the International Warranty. See Table of Contents.
IMPORTANT: Registration lists must be maintained by the factory and dealer in some countries by law. It is our desire to have
ALL products registered at the factory should it ever be necessary to contact you. Make sure your Mercury Marine distributor or
Mercury Marine authorized dealer fills out the warranty registration card immediately and sends the factory copy to the Marine
Power International Service Center for your area.
Warranty Policy–Diesel Models
High‑Output Recreational Use Worldwide Limited Warranty
What is Covered
Mercury Marine warrants each new engine/drive package (Product) to be free of defects in material and workmanship during
the period described following.
Duration of Coverage
The warranty period begins on the date the product is first sold to a recreational‑use retail purchaser or the date on which the
product is first put into service, whichever occurs first. This Limited Warranty provides coverage for two (2) years or 1000 hours
of use, whichever occurs first. Commercial use of the product voids the warranty. Commercial use includes any work or
employment related use of the product, or any use of the product which generates income during any part of the warranty
period, even if the product is only occasionally used for such purposes. The repair or replacement of parts, or the performance
of service under this warranty does not extend the term of this warranty beyond its original expiration date. Unexpired warranty
coverage can be transferred from one recreational use customer to a subsequent recreational use customer upon proper
re‑registration of the product.

Section 1 - Warranty
90-8M0069748 eng APRIL 2012 Page 3
High-Output Rating
A High‑Output Rating applies to variable load applications where full power is limited to one (1) hour out of every eight (8)
hours of operation. Reduced power operation (the 7 hours out of 8 hours in which the engine is not operated at full power) must
be at or below cruise speed. Cruise speed is dependant on the engine's maximum engine rated speed (RPM):
Full Power Engine Rated Speed (RPM) Cruise Speed
Reduction from Engine Rated Speed (RPM)
3500–4500 RPM 400 RPM
This rating is for pleasure (non–commercial) applications that operate 500 hours or fewer per year.
Conditions That Must Be Met to Obtain Warranty Coverage
Warranty coverage is available only to retail customers that purchase from a Dealer authorized by Mercury Marine to distribute
the product in the country in which the sale occurred, and then only after the Mercury Marine specified pre‑delivery inspection
process is completed and documented. Warranty coverage becomes available upon proper registration of the product by the
authorized dealer. Inaccurate warranty registration information regarding recreational use, or subsequent change of use from
recreational to commercial (unless properly re‑registered) may void the warranty at the sole discretion of Mercury Marine.
Routine maintenance outlined in the Operation, Maintenance, & Warranty Manual must be timely performed in order to obtain
warranty coverage. Mercury Marine reserves the right to make any warranty coverage contingent upon proof of proper
maintenance.
What Mercury Marine Will Do
Mercury Marine’s sole and exclusive obligation under this warranty is limited to, at our option, repairing a defective part,
replacing such part or parts with new or Mercury Marine certified re‑manufactured parts, or refunding the purchase price of the
Mercury Marine product. Mercury Marine reserves the right to improve or modify products from time to time without assuming
an obligation to modify products previously manufactured.
How to Obtain Warranty Coverage
Warranty claims must be made through a Mercury Marine authorized repair facility. The customer must provide Mercury Marine
with a reasonable opportunity to repair and reasonable access to the product for warranty service. The purchaser shall not,
unless requested by Mercury Marine, ship the product or parts of the product directly to Mercury Marine.

Warranty coverage may be terminated for used product obtained in any of the following ways:

inconvenience, slip fees, insurance coverage, loan payments, loss of time, loss of income, or any other type of incidental or
consequential damages are not covered by this warranty. Also, expenses associated with the removal or replacement of boat

including Mercury Marine authorized dealers, has been given authority by Mercury Marine to make any affirmation,
representation, or warranty regarding the product, other than those contained in this limited warranty. If such affirmation,
representation, or warranty is made, it shall not be enforceable against Mercury Marine.

direct result of corrosion for the period of time described in the following:
Duration of Coverage
This limited corrosion warranty provides coverage for three (3) years from either the date the product is first sold, or the date on
which the product is first put into service, whichever occurs first. The repair and replacement of parts, or the performance of

coverage can be transferred to subsequent (non‑commercial use) purchaser upon proper re‑registration of the product.
Warranty coverage may be terminated for used product repossessed from a retail customer, purchased at auction, from a
salvage yard, or from an insurance company that obtained the product as a result of an insurance claim.

the boat, and routine maintenance outlined in the Operation, Maintenance & Warranty manual must be timely performed
(including without limitation the replacement of sacrificial anodes, use of specified lubricants, and touch‑up of nicks and
scratches) in order to maintain warranty coverage. Mercury Marine reserves the right to make warranty coverage contingent
upon proof of proper maintenance.
What Mercury Will Do

part or parts with new or Mercury Marine certified re‑manufactured parts, or refunding the purchase price of the Mercury

Engine Data Label
A tamper‑resistant engine data label is affixed to the engine at the time of manufacture. It contains important information. Note
that the engine data label will not affect the fit, function, or performance of the engine and neither boatbuilders nor dealers may
remove the engine data label or the engine component it is affixed to before sale. If modifications are necessary or the engine
data label is damaged, contact Mercury Marine about the availability of a replacement.
The owner or operator is not to modify the engine in any manner that would alter the horsepower or allow exhaust gas emission
levels to exceed their predetermined factory specifications.

Features and Controls
Audio Warning System
Your power package is equipped with an audio warning system. The audio warning system monitors critical components and
informs the operator when a malfunction has occurred. The warning system is not capable of protecting the power package
from damage caused by a malfunction.
When an electronic control system detects a recordable malfunction, the audio warning system will sound to alert the operator.
The duration and type of horn sound depend upon the nature of the fault condition. In the case of any horn sounding, the user
should refer to the helm displays to understand the specific situation.
For the operator to view the fault code of the malfunction indicated and any recommended actions, the power package must be
equipped with a gauge package that supports the warning system and can display fault codes.
The following instruments have screens that display fault codes:
• VesselView
• SmartCraft System Tachometer
• SmartCraft System Speedometer
NOTICE
The sound from an audio warning horn indicates that a critical fault malfunction has occurred. Operating a power package
with a critical fault can damage components. If the audio warning horn emits a sound, do not continue operations unless
avoiding a hazardous situation.
If the audio warning sounds, stop the engine immediately if you are not in a hazardous situation. Investigate the cause and
correct it, if possible. If you cannot determine the cause, consult an authorized repair facility.
Digital Throttle and Shift
Digital Throttle and Shift (DTS) operating instructions are provided in a separate manual. Refer to Mercury Diesel's SmartCraft
and DTS Operator's Manual.
Instrumentation
VesselView
Your power package may be connected to a SmartCraft VesselView display. The interactive VesselView display continuously
reports real‑time information about speed, performance, engine fault codes, fuel status, water temperature and depth, and
other operating data. When VesselView detects a problem with any connected system, it displays an alarm message to the
boat operator.
27198
VesselView
VesselView may also be connected to other vessel systems such as GPS, generators, and cabin environmental controls. This
vessel integration allows the operator to monitor and control a wide range of vessel systems from a single display.
Refer to your VesselView operations manual for detailed instructions on how to operate this display.

90-8M0069748 eng APRIL 2012 Page 11
SmartCraft Speedometer and Tachometer Digital Gauges
The SmartCraft instrument package, if equipped, augments the information provided by VesselView. The instrument package
may display:
• Engine RPM
• Boat speed
• Coolant temperature
• Oil pressure
• Battery voltage
• Fuel consumption
• Engine operating hours
SmartCraft tachometer and speedometer
a - Tachometer
b - Speedometer
c - LCD display
The SmartCraft instrument package also aids in identifying the fault codes associated with the engine audio warning system.
The SmartCraft instrument package displays critical engine alarm data and other potential problems on its LCD display.
For basic operation information on the SmartCraft instrument package and for details on the warning functions monitored by the
system, refer to the manual provided with your gauge package.
System Link Digital Gauges
Some instrumentation packages include gauges that augment the information provided by VesselView and the SmartCraft
tachometer and speedometer. The owner and operator should be familiar with all the instruments and their functions on the
boat. Because of the large variety of instrumentation and manufacturers, have your boat dealer explain the gauges and normal
readings that appear on your boat.
The following types of digital gauges may be included with your power package.
