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.
