    150 4-Stroke Cutting Out

    I need some help everyone! I have a 2013 150 4-Stroke (SN: 2B059230) that started cutting out this trip out.

    Engine runs smooth and normal at startup. Trim works fine up and down.

    Upon take off the engine starts cutting out and shaking violently at 2700 RPM's. Will not go any higher and trim up will not work, but trim down does.

    Drop below 2600 RPM's and engine is back to running smooth but trim up still does not work, trim down does still work.

    Drop below 1500 RPM's and engine is still smooth and trim up and down start working again.

    No beeps and no alerts on smartcraft gauge.

    Any ideas?

    Probably need to get the engine on the Computer Diagnostic System (G3) to monitor and made sure that the shift position is reporting correctly (as well as a number of other items, including printouts of the Run History and Freeze Frame (Fault) History).

    To any following this we were able to resolve the problem this weekend. The screw that holds the Pin Eye Rod in place was missing. Allowing the Pin Eye Rod to rotate and cause the ECM to think the trim was way too high. With the screw in place the trim goes from 0 to 14. While the screw was missing the trim reported back at 25.
