Reliable Low-Speed Marine Power for Yachts and Professional Vessels

The New 22.0 EDE D-NET 22 kW 60 Hz Marine Diesel Generator is a low-speed, electronically governed marine diesel generator set developed to provide stable onboard electricity for motor yachts, sailing yachts, cruising catamarans, passenger vessels, commercial workboats, and other professional marine applications.

Designed for compatible 60 Hz marine electrical systems, the Westerbeke 22.0 EDE D-NET 22 kW delivers 22.0 kW of electrical power while operating at 1800 RPM. Its naturally aspirated four-cylinder diesel engine, brushless four-pole alternator, electronic governor, electronic voltage regulation, freshwater cooling, EZ-Bleed fuel system, digital diagnostics, remote-start capability, and automatic safety shutdowns make it a dependable source of auxiliary power.

The standard single-phase configuration supplies 120/240V AC power and is rated at approximately 183.3 amps at 120V or 91.7 amps at 240V. Westerbeke’s documentation also references three-phase configurations for applications requiring an alternative electrical arrangement.

Its 22 kW capacity may support compatible marine air-conditioning systems, refrigeration equipment, water makers, battery chargers, freshwater and seawater pumps, navigation electronics, communication equipment, galley appliances, lighting, entertainment systems, and other substantial onboard loads.

The original 22.0 EDE D-NET 22 kW is no longer in production. A unit advertised as new will generally be unused dealer inventory, warehouse stock, or a surplus generator rather than a recently manufactured model. Customers should therefore confirm its serial number, production date, storage condition, electrical configuration, included accessories, and warranty eligibility before ordering.

Customers looking for the Westerbeke 22.0 EDE D-NET 22 kW for sale should also confirm the vessel’s electrical demand, machinery-space dimensions, voltage, phase, exhaust arrangement, cooling-water supply, optional sound enclosure, and installation accessories.

Purpose-Built Westerbeke Marine Generator Engineering

The Westerbeke EDE D-NET generator range was developed specifically for onboard marine electricity generation. Unlike portable generators or general industrial units adapted for vessel use, the 22.0 EDE D-NET 22 kW integrates marine cooling, water-injected exhaust compatibility, digital monitoring, electronic speed control, voltage regulation, vibration isolation, remote operation, and service-friendly construction.

The generator is designed for operating conditions that may include:

• Continuous vessel movement and vibration
• Salt-laden marine air
• High machinery-space humidity
• Restricted ventilation
• Changing electrical demand
• Extended operation away from shore power
• Simultaneous operation of multiple onboard systems
• High startup demand from compressors and electric motors

The D-NET platform was offered with Westerlink communication or optional NMEA 2000-compliant databus communication. This allowed compatible generator information to be transmitted through a vessel’s networked monitoring system rather than requiring separate analogue wiring for every monitored function.

Customers comparing the Westerbeke 22.0 EDE D-NET 22 kW price should consider more than its rated electrical output. Low-speed operation, electronic governing, digital diagnostics, alternator construction, cooling-system design, safety protection, service accessibility, installation compatibility, replacement-parts support, and optional sound attenuation all contribute to its overall value.

Smooth Four-Cylinder Diesel Performance

The Westerbeke 22.0 EDE D-NET 22 kW uses a naturally aspirated, four-cylinder, four-stroke diesel engine designed to provide smooth and dependable generator operation.

Its published engine characteristics include:

• Four cylinders in a vertical inline arrangement
• Four-stroke diesel operation
• Naturally aspirated air intake
• Indirect fuel injection
• Approximately 134.1 cubic inches or 2.197 litres of displacement
• 3.43-inch bore
• 3.64-inch stroke
• 22.6:1 compression ratio
• Electronic engine governing
• 1800 RPM operation at 60 Hz
• Approximately 37 horsepower at 1800 RPM
• Cast-iron cylinder head and block
• Forged crankshaft supported by five main bearings
• Overhead valves

These specifications are taken from Westerbeke’s official advanced technical literature for the 22.0 EDE D-NET 22 kW.

The four-cylinder configuration provides smoother power delivery than smaller single-cylinder, twin-cylinder, and many three-cylinder generator platforms. Its 1800 RPM operating speed also reduces mechanical frequency compared with high-speed 3600 RPM generator sets.

Lower-speed four-cylinder operation may contribute to:

• Reduced vibration
• Smoother power delivery
• Lower operating noise
• Improved onboard comfort
• Better performance during extended operation
• Reduced mechanical stress when correctly maintained

A properly sized diesel marine generator allows vessel owners to operate major electrical systems while underway or at anchor without relying continuously on marina shore power.

22.0 kW Single-Phase Electrical Output

The standard Westerbeke 22.0 EDE-614 configuration provides the following electrical ratings:

Electrical Specification	Rating
Rated Electrical Output	22.0 kW
Voltage	120/240V
Frequency	60 Hz
Electrical Configuration	Single Phase
Number of Wires	Four
Power Factor	1.0
Rated Current	183.3/91.7 Amps
Operating Speed	1800 RPM
Starting Method	Remote Electric Start
Alternator Type	Brushless, Four Pole

The generator platform could also be adjusted for 50 Hz operation, producing 17.0 kW at 230V and 1500 RPM. Westerbeke’s documentation additionally states that three-phase configurations were available at compatible ratings.

The vessel’s normal electrical demand should remain within the generator’s rated output while preserving sufficient reserve for equipment startup.

Motor-driven systems can draw considerably more electrical current during startup than during normal operation. This commonly applies to:

• Marine air-conditioning compressors
• Refrigerators and freezers
• Water makers
• Freshwater pumps
• Seawater pumps
• High-output battery chargers
• Ventilation motors
• Hydraulic power packs
• Galley appliances
• Laundry equipment

An undersized generator may experience:

• Voltage drop
• Frequency instability
• Difficult motor or compressor starting
• Excessive engine loading
• Circuit-breaker operation
• Protective shutdown
• Increased exhaust smoke
• Reduced generator service life

A professional marine electrical load assessment should consider continuous demand, startup current, simultaneous equipment operation, battery-charger consumption, operating reserve, and possible future additions.

Selecting an excessively large generator is not always the correct solution. A generator that spends long periods operating at very light load may not achieve ideal engine operating temperature or combustion conditions. The most appropriate generator is one sized around the vessel’s realistic operating profile.

Electronic Governing for Stable Frequency

One of the principal features of the22.0 EDE D-NET 22 kW is its electronic engine governor.

The governor automatically adjusts fuel delivery as connected electrical demand changes. When a large compressor, pump, charger, or motor starts, the generator engine experiences an immediate increase in mechanical load. Without effective speed control, engine RPM and electrical frequency may fall temporarily.

Electronic governing helps the engine maintain its rated 1800 RPM operating speed, supporting stable 60 Hz power and reducing frequency droop.

This can improve the operation of:

• Marine air-conditioning compressors
• Electric motors
• Battery chargers and inverter-chargers
• Refrigeration equipment
• Navigation electronics
• Communication systems
• Lighting circuits
• Monitoring systems
• Sensitive onboard electrical components

Westerbeke’s published specification indicates frequency regulation of approximately 0.3 Hz, or 0.50%, from no load to full load. The manufacturer described the electronic governing system as virtually eliminating the speed droop that may occur when electrical load is applied.

Stable generator performance still depends on correct installation, proper cable sizing, effective grounding, adequate ventilation, suitable circuit protection, and sensible electrical-load management.

Brushless Four-Pole Marine Alternator

The Westerbeke 22.0 EDE D-NET 22 kW uses a brushless four-pole revolving-field alternator designed for dependable onboard electrical production.

Its published alternator features include:

• Brushless construction
• Four-pole design
• Revolving electrical field
• Power takeoff interface
• Class H winding insulation
• Electronic voltage regulation
• Approximately ±2% voltage regulation
• Approximately 0.3 Hz frequency regulation
• Direct-connected centrifugal cooling blower
• Marine electromagnetic-interference protection

Westerbeke specifies voltage regulation of approximately ±2% from no load to full load, supporting consistent electrical output as vessel demand changes.

Brushless alternator construction reduces maintenance associated with carbon brushes while supporting reliable long-term operation.

The four-pole design allows the generator to produce 60 Hz electricity at 1800 RPM. By comparison, a two-pole 60 Hz generator generally operates at 3600 RPM.

Potential benefits include:

• Lower operating speed
• Reduced brush-related maintenance
• Stable electrical output
• Improved winding protection
• Reliable response to changing loads
• Suitability for extended marine operation
• Lower mechanical operating frequency

Westerbeke states that the alternator’s electromagnetic-interference performance exceeds the requirements of most marine radio telephones and standard television equipment.

Electrical performance still depends on correct vessel wiring, grounding, cable sizing, transfer switching, circuit protection, ventilation, and load management.

Freshwater Cooling with Marine Heat Exchanger

The Westerbeke 22.0 EDE D-NET 22 kW uses a freshwater cooling system with a marine heat exchanger.

Internal coolant circulates through the engine and freshwater-cooled exhaust manifold. Seawater removes heat through the heat exchanger before being discharged through the generator’s water-injected exhaust system.

The cooling arrangement includes:

• Closed freshwater coolant circuit
• Marine heat exchanger
• Gear-driven raw-water pump
• Freshwater-cooled aluminium exhaust manifold
• Coolant-recovery tank
• 45-degree water-injected exhaust elbow
• Thermostatically controlled engine temperature

The published cooling-system capacity is approximately 6 US quarts or 5.7 litres. The generator uses a 1-inch seawater connection and a 3-inch outside-diameter exhaust-elbow connection.

A properly maintained marine generator cooling system supports stable engine temperature, reliable operation under sustained load, efficient heat transfer, and longer service life.

Routine maintenance should include inspection of:

• Engine coolant level and condition
• Raw-water intake and seacock
• Seawater strainer
• Raw-water pump and impeller
• Cooling hoses and clamps
• Heat-exchanger tubes
• Thermostat
• Exhaust mixing elbow
• Wet-exhaust hose
• Waterlift muffler
• Siphon-break arrangement
• Machinery-space ventilation

Restricted seawater flow, a blocked strainer, damaged impeller, fouled heat exchanger, restricted exhaust elbow, or inadequate ventilation may cause overheating even when the generator is operating below its rated electrical capacity.

EZ-Bleed Marine Fuel System

The 22.0 EDE uses Westerbeke’s EZ-Bleed diesel fuel system, designed to simplify operation and routine servicing.

Published fuel-system features include:

• Bosch-type mini fuel-injection pump
• Bosch-type injectors
• Full-flow replaceable fuel filter
• 12V electric fuel-transfer pump
• Fuel supply and return connections
• Self-bleeding fuel arrangement
• Electric fuel shutoff
• Indirect-injection combustion system

The electric fuel-transfer pump assists fuel circulation, while the EZ-Bleed arrangement can reduce the amount of manual bleeding required after routine filter replacement or minor fuel-system servicing.

The published approximate full-load fuel consumption at 1800 RPM is:

Operating Condition	Approximate Fuel Consumption
Full Load at 1800 RPM	1.99 US gal/hr
Full Load at 1800 RPM	7.5 L/hr

Actual fuel consumption may vary according to electrical demand, engine condition, fuel quality, maintenance, installation, machinery-space temperature, and operating environment. 22.0 EDE D-NET 22 kW

Clean diesel fuel remains essential. A properly sized marine fuel-water separator should be installed between the vessel’s fuel tank and the generator.

Westerbeke specifies a minimum 1/4-inch inside diameter for the fuel supply line and a maximum 3/8-inch inside diameter for the return arrangement. Fuel lines should be securely supported, protected from excessive heat, and fitted with appropriate shutoff valves.

Remote Starting, Digital Monitoring and Automatic Safety Shutdowns

The Westerbeke 22.0 EDE D-NET 22 kW includes a digital display and diagnostics panel designed to simplify generator operation and system monitoring.

The D-NET control system can provide information relating to:

• Starting-battery voltage
• Generator voltage
• Generator frequency
• Engine oil pressure
• Coolant temperature
• Exhaust temperature
• Generator operating condition
• System warnings and shutdowns

The panel uses illuminated indicators to provide an at-a-glance view of generator status. Additional operational and diagnostic information can be reviewed through the display without requiring the operator to interpret basic numeric fault codes.

Depending on the installed configuration, generator communication may be provided through:

• Westerlink databus communication
• Optional NMEA 2000-compliant communication
• Remote Westerlink digital display
• Remote NMEA 2000 digital display
• Remote start-and-stop control

Actual communication compatibility should be confirmed from the generator’s serial number, control module, wiring harness, and installed vessel network.

Automatic safety systems are designed to stop the generator when potentially damaging conditions are detected.

Published shutdown protection includes:

• Engine overspeed
• Engine underspeed
• Low engine-oil pressure
• High engine-coolant temperature
• High exhaust temperature

Other standard electrical and control features include:

• AC field breaker
• 40-amp battery-charging alternator
• 12V starting motor
• Glow-plug starting aid
• Remote electric starting
• Power takeoff interface

These features are listed in Westerbeke’s original advanced specification sheet.

Automatic shutdown protection helps reduce the risk of major generator damage but does not replace regular inspection. Operators should continue checking oil level, coolant, seawater flow, fuel supply, belts, hoses, exhaust components, electrical connections, and machinery-space ventilation.

Quiet 1800 RPM Operation

Noise and vibration are important considerations aboard yachts, passenger boats, charter vessels, and liveaboard craft.

The Westerbeke 22.0 EDE D-NET 22 kW combines:

• Low-speed 1800 RPM operation
• A smooth four-cylinder engine
• Tuned air-intake system
• Fail-safe rubber anti-vibration mounts
• Freshwater-cooled exhaust manifold
• Water-injected marine exhaust
• Electronic governing
• Optional acoustic enclosure

Westerbeke described the generator as smooth and quiet, crediting its 1800 RPM operation, four-cylinder engine, tuned intake design, and electronic governor.

A correctly installed quiet marine generator should also include:

• Suitable machinery-space insulation
• A properly sized waterlift muffler
• Correct wet-exhaust routing
• Adequate combustion and cooling ventilation
• Flexible fuel and cooling connections
• Properly supported hoses and electrical cables
• Sufficient maintenance clearance
• Correctly positioned anti-vibration mounts

Final onboard sound levels depend on the complete installation rather than the generator alone. Hull construction, machinery-space insulation, ventilation openings, exhaust layout, hose support, and structural vibration transfer all influence the result.

Optional Westerbeke Sound Guard SST

For installations requiring additional sound attenuation, the Westerbeke 22.0 EDE D-NET 22 kW was available with an optional Sound Guard SST enclosure.

The Sound Guard SST uses a stainless-steel base and frame with powder-coated aluminium panels. Removable panels provide maintenance access while helping reduce airborne generator noise.

Approximate enclosure specifications are:

Measurement	Specification
Length	45.0 in. / 1,143 mm
Width	26.0 in. / 660 mm
Height	27.0 in. / 686 mm
Approximate Enclosure Weight	120 lb. / 54 kg

These dimensions and weight are shown in Westerbeke’s official 22.0/17.0 EDE specification drawing.

Because the original 22.0 EDE D-NET 22 kW is discontinued, current availability of the correct enclosure should be confirmed using the generator serial number and approved Westerbeke documentation.

The enclosure should be selected and installed using the correct dimensional drawing to ensure adequate clearance for airflow, hoses, electrical connections, panel removal, and routine maintenance.

Width	22.4 in. / 569 mm
Height	25.4 in. / 645 mm
Dry Weight	Approximately 829 lb. / 376 kg
Maximum Continuous Inclination	20° in All Directions

The dimensions and weight are published on Westerbeke’s official product-support page and advanced specification sheet.

Before installation, the vessel owner or engineering team should confirm:

• Machinery-space dimensions
• Mounting-point locations
• Generator lifting and removal route
• Dry and operating weight
• Service clearances
• Ventilation requirements
• Raw-water inlet position
• Wet-exhaust routing
• Fuel supply and return connections
• AC cable access
• Starting-battery cable routing
• Remote-control harness routing
• D-NET or NMEA 2000 cable route
• Sound-enclosure clearance
• Access to filters, belts and service points

When replacing an existing boat generator, matching only the electrical rating is insufficient. Voltage, frequency, phase, dimensions, mounting arrangements, weight, cooling requirements, exhaust routing, fuel-system compatibility, electrical protection, switchboard integration, and monitoring systems must also be evaluated.
