John Deere Power Systems has introduced a marinized version of its most powerful diesel, which is now rated up to 610 hp. The 12.5-liter 6125SFM75 is based on the company’s 6125AFM75, redesigned to accommodate seawater aftercooling and higher power.
“We are very pleased to be able to offer marine customers our highest horsepower engine yet,” says Carl Micu, sales product manager for JDPS, in a statement. “Now that the newly configured 12.5-liter engine has an increased M4 rating, customers can get up to 610 hp out of one of our most popular engines.”
The M rating system provides guidelines for engine performance, according to the company. An engine with an M4 rating operates up to 800 hours per year, with load factors less than 40 percent and using full power no more than one hour out of each 12 hours of use. The engine is available at three other ratings: M3 (526 hp), M2 (449 hp) and M1 (380 hp). For comparison, the 380-hp M1 version can be operated 24 hours a day at full power.
“The new 6125SFM75 marine engine is perfect for such applications as charter fishing boats, pilot boats, dive boats and planing hull commercial fishing boats, as well as trawler yachts and heavy-duty recreational applications,” says Micu.
Based in Waterloo, Iowa, John Deere now offers marine engines from 80 hp to 610 hp that meet EPA Tier 2 emissions requirements. www.johndeere.com/marine
