    Thank you. 

    Could there be a mistake re UL vs ULS? I was told this is an 80HP engine, any way to visually inspect whether it is 80 or a 100HP?

    Lastly, to confirm, this has a 2000 Hours TBO?

    Thank you kindly!

    What color are the valve covers? (Black or Green??).  (see https://www.rotax-owner.com/en/support-topmenu/technical-information/rotax-engine-specifications )

    The factory says that 4425258  is a ULS.  Do you have the engine logbook?  Are you sure you did not misread the serial?

    There is perhaps an infinitesimal chance that your engine could have been built up out of recycled parts, and a non-original serial tag was attached - but I think that is highly unlikely...

    Hello again,

    Turns out the serial number provided to me was read off a book. The engine serial number stamped is: 4404508

    Any info/help would be appreciated!

    Thank you

     912 UL2 

     309120010

    TBO depends upon whether or not all service bulletins have been complied with ... for 912UL TBO extension info, consult sb-912-057-ul
