    Engine break in fault code?

    250 pro xs

    How long does the engine break in fault code continue to show up. I have 5-6hrs on the motor now and the code still shows up. Does it end at 10hrs?

    I thought it should be two hours. If you go into the alarms page, it will show the countdown clock.

    The clock will only count down when you meet a certain set of parameters. Did you follow the break-in procedure in your manual?

    To add to my issues with this motor after close to the last run of the day when I came off pad the motor seemed to develop a shake rough idle but only when in gear. Seems like maybe a loose wire or fouled plug. Haven’t had time to look into it more. Otherwise it seemed to run good and didn’t show any alarms other then the break in code

    Only if you are not doing the break-in properly.

    To the OP:
    CHECK TO SEE WHAT YOUR SMARTCRAFT LISTS AS TIME REMAINING.

    Can’t say I could have done it any better other than not doing all 4 hrs at once plus I had to go full throttle to hit mid 4K on my boat with trim and plate buried. And I did have a 10 min period I had to limp back to ramp after my new fury 4 let go of a blade(mercury replacing under warranty)

    It will only count off minutes as long as you are doing it right. You go by the book and it should count off in 3 hrs

    Alright I guess 20hrs it is don’t know what else to do watched my rpms through my smartcraft for 2hrs of run time and varied rpms to stay in the 4-5000ish range. Since then I can’t say I ever maintained a specific rpm for beyond a 5min period. The manual break in is very vague

    Yeah waiting on a call back and to get a new coil cable. The motor does seem to still be using a lot of oil

    Should not be anymore than 4 hours, if done properly.
    You should not have to "go full throttle" to hit the required break-in RPM's.

    I'm calling BS! The smartcraft manual said it would go off at 20 hrs, said nothing about only if break in was perfect. Besides that; all it says after the initial hour is to stay between certain rpm, and no wot for more than a few 15 seconds I think. What is there to do wrong?

    Jason: They will use more oil than normal up to around 10 hrs or so. Had a 16, and now an 18, and both used more oil than normal for awhile, then went to normal consumption.

    Sorry....but not B.S........just experience!

    If the PCM does not see the RPM's within the PROPER window the Break-In clock will NOT count down. I did mine in 4 hours total time, over the course of two days, to achieve a couple of heat cycles.

    Savage is not BSing. My last two new motors only had 120min on the break in clock in my Mercmonitor. I also just paged through my Mercmoniotor manual and break-in time is not mentioned.

    Back to the OP, you have a thread about a coil wire not hooked up properly to where a cylinder was not firing. This condition could prevent the break-in clock from counting down AND explain why you had to go to WOT to get up to get RPMs up. Additionally, as long as it is break in mode, it will be double oiling.

    From the very beginning the most rpms I could pull with both a 24 fury and a 25 tempest was 4700rpms and only able to get that with throttle buried. That’s having trim fully in and a jackplate at the lowest point. This is a heavy 21’ tournament loaded rig. At that time I don’t think the #5 cylinder had a spark issue as everything appeared to run fine. After I hit about 2hrs I opened it up with trim and raised the plate and hit 69mph and 5800rpms. Even Sunday I was able to hit 68 loaded. Then the spark issue started or at least I noticed it and couldn’t run it anymore as I was in a no wake area

    to add Sunday I put about 3hrs on the motor and it was 90% fishing rough water so most times I had the trim down and plate and was only running mid 40s varying throttle so that puts me right back into the break in requirement

    Looking forward to to hear what the mechanic has to say.

    Jason- please see the Forum Announcements, and provide the REQUIRED info when posting. Thanks!

    Since you had a plug wire loose- that can affect the possibilities (especially with how the engine is running).

    Get the engine to your DEALER and have the problems corrected.

    Regarding the Break-in Clock: It will be 120 minutes (or less), depending on the PCM Calibration.

    Clock ONLY counts down when:

    -There is HIGH LOAD (trim/jackplate tucked)

    -Engine RPM's are ABOVE 3500 RPM's.

    I have seen pontoons with over 100 hours, still in break-in (because all they do is putter around with them).

    I don't think you were hitting 68 MPH with the end missing off a spark plug wire.........The end had to be on the spark plug cable.
