Product catalog summary

Specifications
The N6.300 E propulsion engine features a power output of 224 kW (305 hp) at the crankshaft, with a displacement of 6.8 liters. It is configured with 6 cylinders in line and operates as a 4-stroke diesel engine. The bore and stroke measure 106.4 x 127 mm, and it has a compression ratio of 17.0:1. The engine's rated speed is 2600 rpm, with an idle speed of 650 rpm. It delivers a peak torque of 1005 Nm at 2000 rpm and has a dry weight of 735 kg. The engine base is John Deere, and it uses a rotary fuel injection pump that is electronically controlled. The air intake is turbocharged with an air-to-seawater aftercooler, and it features a closed cooling system with a heat exchanger. The mounting angle is 9° front up and 0° front down. The alternator is 24 Volt, 50 Amp, and the engine complies with IMO Marpol Annex VI and NRMM (97/68/EC) Tier 2 emission standards.

Technical Description
The engine block includes replaceable wet-type cylinder liners and a water-cooled exhaust manifold. The fuel system features a fuel filter and a mechanical fuel injection pump that is electronically controlled. The lubrication system includes a replaceable full-flow oil filter, oil dipstick, and oil cooler. The cooling system is closed with a heat exchanger, gear-driven self-priming raw water pump, coolant circulating pump, and water-cooled exhaust elbow. The electrical system includes a 24V 50A alternator, 24 Volt starter motor, and complete instrumentation with key switch and alarms. The air intake is turbocharged with an air-to-seawater aftercooler. Other features include a flywheel SAE 3, flexible engine mounting, and damper pulley.

Optional Equipment & Accessories
Options include keel cooling adaptation, dry exhaust elbow, complete marine propulsion systems, marine transmission adaptation kits, throttle and shift controls, additional instrumentation, flying bridge extension harness, rigid engine mounting, power take-off, and type approval.

Rating
The engine is rated for up to 1000 annual operating hours with a load factor up to 35%. Full power can be used for no more than 30 minutes out of each 8 hours of operation, with the remaining time at or below cruising speed.
