OPERATION

The engine break‑in procedure for your OptiMax engine 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.
First hour
• Allow engine to warm‑up for 30–60 seconds.
• Avoid continuous operation at idle speed for more than 10
minutes.
• Run the engine the majority of time between 3000–4500 RPM,
approximately three quarter throttle.
• Vary engine speed; change engine speed approximately
every two minutes.
• Short bursts of full throttle for periods up to 10 seconds are
acceptable.
Next three hours
• Change engine speed every 10 minutes.
