Outboard Care

To keep your outboard in the best operating condition, it is
important that your outboard receive the periodic inspections and
maintenance listed in the Inspection and Maintenance
Schedule. We urge you to keep it maintained properly to ensure
the safety of you and your passengers, and retain its dependability.
Record maintenance performed in the Maintenance Log at the
back of this book. Save all maintenance work orders and receipts.
SELECTING REPLACEMENT PARTS FOR YOUR
OUTBOARD
We recommend using original Mercury Precision or Quicksilver
replacement parts and Genuine Lubricants.
