Picking up a new Merc 225 Pro XS late next week. Im sure the dealer will have break in advice, but I was wondering what the board has to say.
Thanks

Use the owners manual, not the forums.
This is what I recommend.

Thank You Leon Pugh
checkout the FAQ on that subject

Is this a new 2-stroke or 4-stroke ProXS?

In the CORRECT forum for the new 225 ProXS (This one if it's a powerhead on your Optimax, the FOURSTROKE FORUM if it's a new ProXS V8), you will find instructions in the FAQ Section that outline a combination of what's shown in the engine owners manual AND some very helpful into to potentially extend the engine's health and life.Originally Posted by wjh
Sorry Leon... Heat cycling isn't found in ANY of the manuals. Only HERE in the Forums.

In General: 10 Hours of Break-in (Total).
For the First Two Hours of Operation: Start the engine and allow it to reach operating temperature. Get the boat on plane, and operate the engine at up to 4500 RPM's (Important: Vary engine RPM's every 2-5 minutes). Run the engine to FULL THROTTLE for 60 seconds once every 10 minutes (approximately).
Additional Recommendation: Though not listed in Owner's Manuals, it is an excellent idea to have the engine make at least two (2) complete HEAT CYCLES during the first 2 hours of operation. A heat cycle consists of: Ambient temp, start engine, come to operating temp, run engine for at least 5 minutes on plane, return to idle, stabilize engine temp, shutdown engine and allow to cool to ambient temp. Note: Heat cycles CAN be done on different days.
For the Next 8 Hours of Operation: Full throttle may continue to be used, but engine RPM's should be varied/changed at least once every 5 minutes.
