Section 1 - WARRANTY

Emission Control Information Label

A tamper‑resistant emission control information (ECI) label is affixed to the engine in a visible location at the time of
manufacture. Please note that the emissions certification will not affect the fit, function, or performance of the engine.
Boatbuilders and dealers may not remove the label or the part it is affixed to before sale. If modifications are necessary, contact
Mercury MerCruiser about the availability of replacement decals before proceeding. In addition to the required emissions
statement, the label lists the family, applicable emission standard, and date (month, year) of manufacture.
IMPORTANT: Engines designated as exempt from either Federal EPA or California emission control regulations are not
covered by a separate emission control component warranty. The product's Mercury MerCruiser manufacturer's warranty is not
affected by the engine's designation under Federal EPA or California emission control regulations.

Owner Responsibility

The operator must have routine engine maintenance performed to maintain emission levels within prescribed certification
standards.
The operator may not modify the engine in any manner that alters the horsepower or allows emissions levels to exceed factory
specifications.
Warranty Policy—Diesel Models
High‑Output Recreational Use 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
specific coverage in the regions stipulated in the Global Warranty Charts for pleasure (noncommercial) applications, or the
accumulation of 1000 hours of operation, whichever occurs first. Commercial use of a product that is registered as pleasure
voids the warranty. Commercial use includes any work related 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 registration of the product.
HIGH‑OUTPUT RATING: 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 seven hours out of eight 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)
4000 RPM
This rating is for pleasure (noncommercial) applications that operate 500 hours or fewer per year.
