Sample of Engine ID's
These engines were built during the joint venture with OMC and were painted a dark charcoal color. They were usually named by long character strings that contain two numbers followed by a series of letters.
Examples:
1.) The two numbers are the displacement
2.) Next is a letter that indicates who made the base engine. G=GM, F=Ford
3.) After that, one or two letters that note the fuel system and/or output.
L = limited
s = superior
X = exceptional
i = fuel injected (no I means carbureted) .
Then a space
4.) Then one letter for the steering system.
P = power steering
M = manual steering
I = inboard
X = exact steering
J = Jet Drive
5.) The next two letters are the most important for finding parts. These are random letter pairs that indicate the years of production for the engine.
MD = 1993-1994
HU = 1994-1995
NC = 1995-1996
LK = 1996-1997
BY = 1997-1998
WT = 1998-1999
EF = 1999-2000
6.) The next letter is random and is used for version control.
An "A" may not be the first version.
A "C" may not have been built before an "S".
An "S" in one engine's name may not mean the same thing as an "S" in another engine's name, especially if the engines have different displacements or production years.
7.) Some names have the letters "CE" at the end. This indicates the engine meets certain emission requirements. The only service part affected is the ECU. These part numbers are noted when needed in the catalogs. These engines went out of production in 2000.
