Outboard Installation; Important Information - Mercury 135 Pro XS OptiMax Manual

Important Information

BEFORE STARTING THE ENGINE
Lack of oil pressure in the system can cause severe internal
engine damage during start‑up. Prime the oil injection pump on
new or rebuilt engines or after performing maintenance on the
oiling system.
Refer to Priming the Oil Injection Pump for instructions.
FUEL REQUIREMENTS
Do not use premixed gas and oil in this engine. The engine
automatically receives extra oil during engine break‑in. Use a
fresh supply of the recommended gasoline during engine
break‑in and after engine break‑in.
OIL RECOMMENDATION
Recommended Oil
OptiMax Oil or Premium Plus TC‑W3 is a higher grade oil that
provides increased lubrication and extra resistance to carbon
buildup when used with good or varying grades of gasoline.
IMPORTANT: Oil must be NMMA certified TC‑W3 2‑Cycle oil.
Periodically consult with your dealer to get the latest gasoline
and oil recommendations. If Mercury Precision or Quicksilver
2‑Cycle Outboard Oil is not available, substitute another brand of
2‑Cycle outboard oil that is NMMA Certified TC‑W3. The use of
an inferior 2‑Cycle outboard oil can reduce engine durability.
Damage from use of inferior oil may not be covered under the
limited warranty.
