FORT LAUDERDALE — Cummins MerCruiser Diesel showcased a pair of its new TDI 4.2-liter diesel inboards at the Fort Lauderdale International Boat Show, marking the beginning of its business relationship with Volkswagen. The German engine company is now manufacturing the 4.2-liter V-8, which carries a 350-hp rating, under the CMD brand name.
Volkswagen is also manufacturing — and marinizing — 1.9-, 2.5- and 3.0-liter diesels for CMD at its plant in Salzgitter, Germany. The 1.9-liter is an inline 4-cylinder engine with a 40- to 75-hp rating; the 2.5-liter, an inline 5-cylinder engine, has a rating of 55 to 165 hp; and the 3.0-liter V-6 is rated from 225 to 265 hp.

The twin-TDI (turbocharged direct injection) diesels were mounted in a custom-built 37-foot center console from Statement Marine — the same boat that recently attempted to break the New York-to-Bermuda Challenge record but failed because of weather conditions.
"Volkswagen is going to be an outstanding partner with the technology they have and the performance of their engines," said Kevin Grodzki, Mercury Marine president of sales and marketing and commercial operations." The scope and scale that they have as a manufacturer and a partner is going to change the industry. And with our distribution and service network, that technology will be brought to a much wider base."
Potential applications could include twin 4.2-liter engines installed in vessels as large as 40 feet, including express cruisers and sportfishing boats, according to CMD. The 350-hp engine also could find its way into large runabouts. Additionally, the diesels in the CMD lineup could be candidates for trawlers and sailboats.
The EPA Tier 2 diesels push the Statement Marine vessel to a top speed in the low 50-mph range, said the owner of the boat, Chris Fertig, who was running it for media representatives at the boat show. Pricing information was unavailable.
