Description

John Deere Power Systems has introduced the new 4045SFM85 marine engine to its powerful, reliable marine engine offerings. The new 4.5L engine offers high power to weight ratio for repowering and new boat construction, and is ideal for planing and semi-displacement hulls.

The new PowerTech 4045SFM85 has two ratings for light-duty commercial vessels, highspeed governmental applications and high-speed pleasure craft, which includes an M4 rating with 205 kW (275 hp) at 2600 rpm and M5 rating with 235 kW (315 hp) at 2800 rpm.

The PowerTech 4.5L engine ratings join the existing lineup of John Deere Marine Tier 3
propulsion engines. The 4045SFM85 ratings will meet U.S. Environmental Protection Agency Marine Tier 3 and Recreational Craft Directive II emissions regulations, as well as International Maritime Organization 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 inboard 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 piece 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.
