Engine Break-In Procedure - Mercury 200 OptiMax DTS 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 premixed 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
high 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.
