MD = 1993-1994 BY = 1997-1998
HU = 1994-1995 WT = 1998-1999

LK = 1996-1997
The next letter is also 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. When needed this code is noted in the charts. There are instances where it is needed to find the right column for an engine.
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.
4.3GLPBYC = 4.3L, G=GM, L=limited output, carbureted (no i), P=power steering, BY=built 1997-1998, C=service code for version control.
5.8FSiPNCACE = 5.8L, Ford, Superior output, injected, power steering, NC=built 1995-1996, A service code, certified emissions.
7.4GLPHUS = 7.4L, GM, limited output, carbureted, power steering, HU=built 1994-1995, S service code.
3.0GLMMDA = 3.0L, GM, LIMITED output, carbureted, manual steering, MD=built 1993 1994, A service code.
Red Engines, 2000
Beginning in 2000 the gas engines are painted red again. The naming system was also changed. The first part of the name is the same as the charcoal engines, up to the letters for the fuel system.
- The two numbers are the displacement.
- Next is a letter that indicates who made the base engine. New engines have been added that use Volvo Penta's new Ocean Series sterndrives, these engines have an OS for this letter.
- After that, one or two letters that note the fuel system and/or output.
- For 3.0L only, there is an M or P for the steering
- For Inboard engines only, there is an I after the lower case i.
- Then a dash (-) followed by a one or two letter suffix. This is the major change from the charcoal engines above.
- The first letter is the version control, this is present on all current engines. .A is the first version, -B is the second version, etc. There is no link between the suffix and production years. All engines with .A were not built the same year. A 5.7GXi-B and a 5.0GXi-B are not similar. A 4.3GL-D is newer than and different from a 4.3GL-C.
- The second letter, if present is always an F, it notes that the engine is freshwater cooled.
Examples: 3.0GLM-C, 4.3GXi-DF, 5.0OSi-E, 8.1GXiI-B
¨Today we have V6 / V8 denoting the number of cylinders and configuration
- a dash followed by the power output of the engine
- a dash if C or E are included (see below)
- optionally the letter C for engines with catalytic converter
- optionally the letter E for engins with EVC
- a dash followed by the version control suffix
