Playing with BIG Blocks
Here’s a sampling of new diesels for power-hungry hulls.

The latest generation of marine diesels deliver massive amounts of dependable power, weigh less, run smoother at low speeds, make less noise, emit no smoke, and are often more fuel efficient than engines produced only a few years ago. A substantial number of the improvements in these new engines result from the extensive re-engineering required to comply with the stringent EPA and International Tier 2 emission specifications.
Engine manufacturers are constantly working to develop the optimum engine for each application, whether slow and steady or short bursts of high power. Although it is a bit of an oversimplification, it can be useful to consider that an internal combustion engine of a given weight can convert a fixed amount of fuel into mechanical energy before it requires a major overhaul. The fuel can be burned slowly, over many thousands of hours, or rapidly, in as little as a few hundred hours. Engines designed to run for many thousands of hours are not necessarily “better” engines than those that will require an overhaul after only one thousand hours, their service life reflects their design for a specific application. ...
