A. Part Number: For part ordering - Note N.S.S. for Reference Numbers, (not shown above) - means Not Sold
Separately by Mercury Marine, however, in some cases, the G.M. Part Number (for the item) is given in the De-
scription Column.
B. Reference Number: For part Shown on exploded parts view.
C. Description: This is the most important column because it gives:
1) Description of Part: Ref. No. 1 is a Cylinder Block Assembly, No. 13 is the Balanced Shaft, etc.
2) What parts are included with a certain part: Notice how the Description of Part, for Ref. Nos. 1, and 10
through 13, are at the left side of the column. Description of Part for Ref. Nos. 2 thru 9 are indented under “Cylin-
der Block”. If Ref. No. 1 (Cylinder Block) was ordered, all indented parts (Ref. Nos. 2 thru 9) would come with
the part. Ref. Nos. 10 thru 14 would not come with Ref. No. 1 and would have to be ordered separately. If 2 Cylin-
der Blocks were listed, both cylinder blocks would come with the indented parts. In some cases, an indented part
will have another part indented under it. The second indented part will come with the first indented part.
3) Serial number break: If serial number information is listed, check product serial number to ensure that
correct part is ordered.
4) Special information: Many times special information will be shown after description such as; L.H. Rotation,
R. H. Rotation, Filter up, Filter Down, etc. This will help in selecting the correct part.
D. Quantity: Quantity that has to be ordered.
E. Special Information Block: Additional information, part numbers for gasket sets, etc.
