Now in its latest edition, the Diesel Directory has become a trusted reference tool across the maritime industry, offering a detailed, no-frills snapshot of the current diesel engine market. Whether readers are repowering an aging workboat or specifying a newbuild, the 2025 guide helps cut through the noise with straightforward, up-to-date data on available engine models, horsepower ranges, and manufacturers.

Compiled and verified by the WorkBoat editorial team, the directory features contributions from top engine builders, distributors, and marine power specialists. “We built this resource with one thing in mind — helping marine professionals make smarter power decisions,” said the editorial staff. “We’re not interested in fluff. Just the facts on diesel power, presented clearly and concisely.”

The Diesel Directory includes engine specs from leading names in marine propulsion and reflects the latest emissions standards, fuel trends, and power demands shaping today’s workboat sector.
