John Deere Power Systems (JDPS), Waterloo, IA, has announced it will begin production on three new PowerTech marine engines, the 6068AFM75, 6090SFM75 and 6135SFM75.
Scheduled to be launched in early 2010, all three engines are designed for recreational and commercial applications and meet the EPA Tier 2 and EU emissions requirements. They are also MARPOL Annex VI compliant.
“All of these engines are optimum choices for cruisers, trawler yachts, houseboats and other recreational applications,” said Dave Flaherty, marine marketing manager for John Deere Power Systems. “The new 6090SFM75 and 6135SFM75 are especially suited for sportfishing boats and other high horsepower applications. The 6068AFM75 is an ideal genset engine for mega yachts, as well as a propulsion engine for trawler yachts and smaller recreational vessels.”
The PowerTech 6068AFM75, which offers a displacement 6.8L, is a six-cylinder, electronically-controlled, turbocharged and air-to-coolant aftercooled marine engine designed with low-speed torque and a power rating of 330 hp. The six-cylinder PowerTech 6090SFM75 – an air-to-seawater aftercooled marine engine – has a larger displacement of 9.0L, offers up to 500 hp and is electronically-controlled and turbocharged.
