MAINTENANCE

Mercury Marine recommends that you have the dealer do
periodic maintenance checks on your power package. Have
them winterize it in the fall and service it before the boating
season. This will reduce the possibility of any problems occurring
during your boating season when you want trouble‑free boating
pleasure.
IMPORTANT: Refer to
Maintenance Charts
(on following pages)
for complete listing of all scheduled maintenance to be
performed. Some listings can be done by the owner/operator,
while others should be performed by an authorized Mercury
Marine dealer. Before attempting maintenance or repair
procedures not covered in this manual, Mercury Marine
recommends purchasing a Mercury Marine Service Manual.
Servicing High‑Horsepower Engines
All high‑performance engines require frequent maintenance and
inspection schedules due to the extreme duty cycles and related
stress these products endure. Failure to follow the detailed
maintenance and service schedule as written and supplied by
Mercury Marine could lead to catastrophic engine failure and
increased owner expense.
