Engine Break-In Procedure - Mercury 200 OptiMax Manual

Engine Break‑in Procedure
IMPORTANT: Failure to follow the engine break‑in procedures can
result in poor performance throughout the life of the engine and
can cause engine damage. Always follow break‑in procedures.
GASOLINE/OIL BREAK-IN MIXTURE
NOTE: Do not use pre‑mixed gas and oil during break‑in. Use
straight gasoline during engine break‑in and after engine break‑in.
The engine break‑in procedure for an OptiMax outboard is
important to ensure proper performance and maximum life from
the engine. The following break‑in procedure allows the internal
engine parts to wear‑in evenly. Incorrect engine break‑in can
shorten the engine life.
The engine automatically receives extra oil during the first hours
of operation. For most boaters this extra oil mode will be complete
in about ten hours.
BREAK-IN PROCEDURE
1. For the first hour of operation, allow the engine to warm up for
30 ‑ 60 seconds.
a. Run the engine at varied throttle settings, the majority of
the time between 3000 and 4500 RPM or three‑quarter
throttle.
b. Change engine speed approximately every two minutes,
and avoid continuous operation at idle speed for more than
ten minutes. Short bursts of full throttle for periods up to ten
seconds are acceptable.
c. Avoid trimming the outboard out (up) beyond a vertical trim
position during operation.
NOTE: It is the driver's responsibility to always drive in a safe
manner. Improper trim angle of the outboard when driving at
speed can be difficult and dangerous. The purpose of specifying
trim angle is to help guide the operator in determining how to put
the proper load on the engine. They are intended to be guidelines
and do not suggest or require unsafe boat operation.
2. For the next three hours of operation, change engine speed
every ten minutes.
