Old Tacoma Marine, Inc.

Enterprise Foundry Co

Known remaining Enterprise diesel engines

Enterprise model numbers are a combination of three different letter designations: "D" for diesel, "M" or "S" for marine or stationary, and a designation that indicates the cylinder size (M, W, G, Q, etc). These three letter designations are followed by the number of cylinders in the model. For example, a DMQ-8 is a marine diesel engine with a 16" bore and 20"e; stroke and eight cylinders.
