must:
    (1) Be attached in such a manner that it cannot be removed without 
destroying or defacing the label;

    (6) date of manufacture [day(optional), month and year];
    (7) The statement ``This engine conforms to [model year] U.S. EPA 
regulations for marine SI engines.'';
    (8) Family Emission Limits (FELs);
    (9) EPA standardized engine family designation;
    (10) Engine displacement [in cubic centimeters]; and
    (11) Advertised power;
    (12) Engine tuneup specifications and adjustments. These should 
indicate the proper transmission position during tuneup, and 
accessories, if any, that should be in operation;

this paragraph. The information deleted from the label must appear in 
the owner's manual.
