Tracker by Mercury Marine Outboard, Mercury MerCruiser
Inboard or Sterndrive Engine (Product) will not be rendered
inoperative as a direct result of corrosion for the period of time
described below.
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 or replacement of
parts, or the performance of service under this warranty, does
not extend the life of this warranty beyond its original expiration
date. Unexpired warranty coverage can be transferred to
subsequent (noncommercial use) purchaser upon proper
reregistration of the product.
CONDITIONS THAT MUST BE MET IN ORDER 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

documented. Warranty coverage becomes available upon proper
registration of the product by the authorized dealer. Corrosion
prevention devices specified in the Operation and Maintenance
Manual must be in use on the boat, and routine maintenance
outlined in the Operation and Maintenance 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.

obligation under this warranty is limited to, at our option,
repairing a corroded part, replacing such part or parts with new

right to improve or modify products from time to time without
assuming an obligation to modify products previously
manufactured.
HOW TO OBTAIN WARRANTY COVERAGE: The customer

inspection to a Mercury dealer authorized to service the product.
If purchaser cannot deliver the product to such a dealer, written
notice must be given to Mercury. We will then arrange for the
inspection and any covered repair. Purchaser, in that case, shall
pay for all related transportation charges and/or travel time. If the
service provided is not covered by this warranty, purchaser shall
pay for all related labor and material, and any other expenses
associated with that service. Purchaser shall not, unless

directly to Mercury. Proof of registered ownership must be
presented to the dealer at the time warranty service is requested
in order to obtain coverage.

use of the product, or any use of the product which generates
income, for any part of the warranty period, even if the product is
only occasionally used for such purposes.

WARRANTY INFORMATION
eng 5
Corrosion damage caused by stray electrical currents (onshore
power connections, nearby boats, submerged metal) is not
covered by this corrosion warranty and should be protected
against by the use of a corrosion protection system, such as the
Mercury Precision Parts or Quicksilver MerCathode system
and/or Galvanic Isolator. Corrosion damage caused by improper
application of copper base antifouling paints is also not covered
by this limited warranty. If antifouling protection is required,
Tri‑Butyl‑Tin‑Adipate (TBTA) base antifouling paints are
recommended on Outboard and MerCruiser boating applications.
In areas where TBTA base paints are prohibited by law, copper
base paints can be used on the hull and transom. Do not apply
paint to the outboard or MerCruiser product. In addition, care
must be taken to avoid an electrical interconnection between the
warranted product and the paint. For MerCruiser product, an
unpainted gap of at least 38 mm (1.5 in.) should be left around
the transom assembly. Refer to the Operation and Maintenance
Manual for additional details.
