OCTOBER 19, 2017 — John Deere Power Systems has added three new marine engines to its range.
The new 4.5 liter PowerTech 4045SFM85 offers high power to weight ratio for repowering and new boat construction, and is well-suited for planing and semi-displacement hulls. Two new auxiliary engines, the 6090HFM85 and 6135HFM85, are specifically designed for radiator-cooled marine gen-set and auxiliary applications.
The 4.5 L PowerTech 4045SFM85 has two ratings for light-duty commercial vessels, high-speed governmental applications and high-speed pleasure craft. The M4 rating delivers 205 kW (275 hp) at 2,600 rpm. The M5 rating delivers 235 kW (315 hp) at 2800 rpm. The 4045SFM85 ratings will meet U.S. Environmental Protection Agency Marine Tier 3 and Recreational Craft Directive II emissions regulations, as well as IMO Tier II standards for commercial and recreational applications. The engine is pending approval by American Bureau of Shipping, DNV GL, Lloyd’s Register and Bureau Veritas and will be the only ABS-certified, 315 hp, 4-cylinder in-board diesel engine.
“We’re excited to offer type approvals for this power range in the near future,” said Heather Balk, marine market planner for John Deere Power Systems. “Type approvals offer peace of mind to boat owners that this new engine from John Deere will pass marine authority safety tests and design reviews.”
The engine uses a waste-gated turbocharger that provides more torque capability at the low and middle rpm range, which is most notable during vessel acceleration, and features replaceable cylinder liners, making it possible to rebuild the engine for extended service life.
NEW MARINE GENSET AND AUXILIARY ENGINES
The new 6090HFM85 and 6135HFM85 engines are specifically designed for radiator-cooled marine genset and auxiliary applications. The new PowerTech 6090HFM85 is rated for variable speed at 242 kW (325 hp) at 2,000 rpm and for generator drive and constant speed auxiliary at 262 kW (351 hp) at 1.800 rpm. The PowerTech 6135HFM85 is rated for variable speed at 373 kW (500 hp) at 2,000 rpm and for a generator drive and constant speed auxiliary at 458 kW (614 hp) at .1800 rpm.
The engines are type approved by the American Bureau of Shipping and are well-suited for gen-set, constant speed and variable speed auxiliary applications, particularly when wet manifolds and marine society classification certificates are desired or required. The ratings of both engines meet U.S. Environmental Protection Agency Marine Tier 3 emissions regulations and are compliant with IMO Tier II standards for commercial applications. .
“We’re excited to offer these additional air-cooled ratings, which are designed specifically for the marine gen-set and marine auxiliary engine markets, to the current 9.0L and 13.5L radiator-cooled, dry exhaust manifold engines,” said Ms. Balk “The range of engine options allow our customers to select the best product for a variety of generator and auxiliary application needs including pumps, winches, cranes and hydraulics.”
