• Serial number and production date
• New, unused, rebuilt, or used condition
• Warranty eligibility
• Voltage and phase
• Installed D-NET control version
• NMEA 2000 or Westerlink configuration
• Sound enclosure and accessories
• Parts and service support
• Packing dimensions and shipment requirements

Quiet Four-Cylinder Power at 1800 RPM

The Westerbeke 15.0 EDT uses a four-cylinder, four-stroke, naturally aspirated diesel engine with a vertical inline configuration. Its displacement is approximately 107.27 cubic inches or 1.758 litres, with a 3.07-inch bore, 3.62-inch stroke, and 22:1 compression ratio. The engine is rated at approximately 25 hp at 1800 RPM.

Key engine characteristics include:

• Four-cylinder vertical inline configuration
• Four-stroke diesel operation
• Naturally aspirated air intake
• 1.758-litre displacement
• Swirl-type combustion system
• Electronic engine governor
• Freshwater cooling
• 1800 RPM operation at 60 Hz
• Cast-iron cylinder block and head
• Forged crankshaft supported by five main bearings

The four-cylinder engine provides smooth power delivery, while the relatively low 1800 RPM operating speed helps reduce mechanical frequency compared with compact 3600 RPM generator sets. Westerbeke also fitted a tuned air-intake silencer and fail-safe rubber anti-vibration mounts to reduce transmitted vibration and intake noise.

This makes the Westerbeke 15 kW marine generator suitable for vessels where dependable power, comfortable onboard operation, and extended generator use are important.

15.0 kW Single-Phase Marine Electrical Output

The standard Westerbeke 15.0 EDT-614 configuration provides 15.0 kW at 120/240V, 60 Hz and 1800 RPM.

Electrical specification	Published rating
Rated output	15.0 kW
Voltage	120/240V
Frequency	60 Hz
Phase	Single phase
Number of wires	Four
Power factor	1.0
Rated current	125/62.5 amps
Engine speed	1800 RPM
Starting method	Remote electric start

The same generator platform was adjustable for 50 Hz operation, where its published rating was 12.0 kW at 230V and 1500 RPM. Westerbeke also offered compatible three-phase versions.

Before purchasing a 15 kW yacht generator, the vessel’s electrical demand should be professionally assessed. Generator sizing should consider:

• Normal continuous electrical consumption
• Air-conditioning compressor startup
• Refrigeration startup current
• Battery-charger and inverter demand
• Water-maker requirements
• Pump and motor loads
• Simultaneous appliance use
• Future electrical additions
• A reasonable operating reserve

An undersized generator may experience difficult motor starting, voltage reduction, frequency instability, overload trips, excessive engine loading, or premature component wear.

A generator that is substantially oversized may also spend too much time operating under light load. Correct sizing should therefore be based on the vessel’s actual load profile rather than simply selecting the largest generator that fits the machinery space.

D-NET Digital Display and Diagnostics

The Westerbeke D-NET control system provides simplified generator operation, system monitoring, and diagnostic information through a digital display.

The panel monitors information such as:

• Engine oil pressure
• Engine-coolant temperature
• Exhaust temperature
• Starting-battery voltage
• Generator voltage
• Generator frequency
• Generator operating status
• Warning and shutdown conditions

Illuminated indicators allow important operating conditions to be reviewed at a glance. Additional information can be accessed through the digital screen, reducing the need to interpret basic numeric fault codes manually.

The generator was supplied with Westerlink communication and could be equipped with NMEA 2000-compliant databus communication. Compatible installations could connect generator data to remote digital displays or a vessel’s networked monitoring system.

NMEA 2000 compatibility should be verified from the serial number and installed electronic package. Some generators may require the appropriate communication module, cabling, termination, and compatible vessel display.

Electronic Governing for Stable Frequency

The Westerbeke 15.0 EDT uses an electronic engine governor to maintain the correct operating speed as electrical load changes.

When a compressor, pump, charger, or motor starts, the generator experiences a sudden increase in load. The governor automatically adjusts fuel delivery to help maintain 1800 RPM and stable 60 Hz output.

Westerbeke specifies frequency regulation of approximately 0.5 Hz, or 0.60%, from no load to full load. The manufacturer describes the electronic governor as virtually eliminating the speed droop that may otherwise occur when electrical loads are applied.

Stable engine speed helps support reliable operation of:

• Marine air-conditioning compressors
• Refrigeration systems
• Battery chargers
• Electric motors
• Navigation electronics
• Communication systems
• Lighting and monitoring circuits
• Sensitive onboard electronics

Generator performance also depends on correct wiring, grounding, cable sizing, circuit protection, ventilation, and sensible load management.

Brushless Four-Pole Alternator

The 15.0 EDT D-NET 15 kW uses a brushless four-pole revolving-field alternator with a direct-connected centrifugal cooling blower.

Published alternator characteristics include:

• Brushless construction
• Four-pole design
• Revolving electrical field
• Single-bearing arrangement
• Class H insulation
• Approximately ±5% voltage regulation
• Approximately 0.5 Hz frequency regulation
• Direct-connected cooling blower
• Marine electromagnetic-interference protection

The four-pole design enables the alternator to produce 60 Hz power at 1800 RPM. A conventional two-pole 60 Hz generator would normally operate at 3600 RPM.

Brushless construction reduces maintenance associated with carbon brushes, while Class H winding insulation supports dependable performance at elevated electrical and machinery-space temperatures. Westerbeke states that electromagnetic interference is controlled to levels exceeding the requirements of most marine radio telephones and standard televisions.

Freshwater Cooling with Marine Heat Exchanger

The 15.0 EDT D-NET 15 kW uses a freshwater-cooled engine with a marine heat exchanger.

Internal coolant circulates through the engine and exhaust manifold. Raw water from the vessel’s seawater intake passes through the heat exchanger, removes engine heat, and is normally discharged through the water-injected exhaust arrangement.

The cooling package includes:

• Closed freshwater cooling circuit
• Marine heat exchanger
• Raw-water pump
• Freshwater-cooled exhaust manifold
• Coolant-recovery tank
• Water-injected exhaust elbow
• Thermostatic temperature control

The published cooling-system capacity is approximately 8 US quarts or 7.6 litres. The generator uses a 1-inch seawater connection and a 2-inch outside-diameter exhaust-elbow connection.

Routine cooling-system maintenance should include checking:

• Coolant level and concentration
• Raw-water intake and seacock
• Seawater strainer
• Raw-water pump impeller
• Heat-exchanger tubes
• Cooling hoses and clamps
• Thermostat
• Exhaust mixing elbow
• Wet-exhaust hose
• Siphon-break installation
• Machinery-space ventilation

Restricted cooling-water flow, a blocked strainer, worn impeller, fouled heat exchanger, damaged exhaust elbow, or poor ventilation may cause overheating even when the generator is operating below full electrical load.

Self-Bleeding Diesel Fuel System

The Westerbeke 15.0 EDT incorporates a self-bleeding diesel fuel system with a 12V electric fuel-transfer pump.

Published fuel-system features include:

• Bosch-type injection pump
• Solenoid fuel shutoff
• Throttle-type injectors
• Primary and secondary replaceable filters
• Electric fuel-transfer pump
• Fuel supply and return connections
• Self-bleeding operation

The recommended fuel-line dimensions listed in the specification are a minimum 1/4-inch inside diameter for the supply line and a maximum 3/8-inch inside diameter for the return arrangement.

Approximate full-load fuel consumption is 1.47 US gallons per hour or 5.6 litres per hour at 1800 RPM. At the 12 kW, 50 Hz rating and 1500 RPM, published consumption is approximately 1.12 US gallons per hour or 4.2 litres per hour.

Actual consumption will depend on electrical loading, fuel quality, installation, maintenance, ambient temperature, and engine condition.

A correctly sized marine fuel-water separator should be installed between the fuel tank and generator. Fuel hoses, shutoff valves, supply lines, and return lines must comply with the vessel’s applicable marine standards.

Automatic Safety Shutdown Protection

The D-NET system monitors important generator operating conditions and can stop the engine when potentially damaging conditions occur.

Published shutdown functions include:

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

The digital diagnostics panel helps the operator identify the condition that caused a warning or shutdown.

Other standard features include:

• AC output circuit breaker
• 50-amp battery-charging alternator
• 12V starting motor
• Remote-start capability
• Coolant-recovery tank
• Oil-drain hose and drip tray
• Belt guard
• Power takeoff interface

Automatic shutdowns reduce the risk of major damage but do not replace routine inspection. Operators should still check engine oil, coolant, seawater flow, fuel supply, electrical connections, exhaust components, and machinery-space ventilation before operation.

Starting and Charging System

The generator uses a 12V DC negative-ground electrical system with a reduction-gear starting motor, solenoid-actuated starting circuit, glow-plug starting aid, and a 50-amp belt-driven charging alternator.

The published specification lists approximately 270 cold-cranking amps for the starting system. Battery selection and cable sizing should still account for cable length, ambient temperature, installation requirements, and applicable marine electrical standards.

The engine’s lubricating-oil capacity is approximately 5.5 US quarts or 5.2 litres, and the lubrication system uses a full-flow spin-on oil filter.

Optional Westerbeke Sound Guard SST

The Westerbeke 15.0 EDT D-NET 15 kW can be fitted with an optional Sound Guard SST acoustic enclosure. The original specification identifies Sound Guard part number 53463 for the digital generator.

The enclosure uses powder-coated aluminium panels supported by a corrosion-resistant stainless-steel base and frame. Its removable panels improve service access while helping reduce airborne generator noise.

Approximate Sound Guard SST specifications are:

Enclosure measurement	Specification
Length	39.5 in. / 1,003 mm
Width	23.2 in. / 589 mm
Height	25.3 in. / 643 mm
Weight	94 lb. / 43 kg

The enclosure increases the generator’s overall installation size and weight. Machinery-space dimensions, panel-removal clearance, ventilation, hoses, and cable routes should be verified before ordering.

Dimensions, Weight and Installation

The Westerbeke model page lists the base generator at approximately:

Measurement	Specification
Length	35.20 in. / 894 mm
Width	19.10 in. / 485 mm
Height	24.00 in. / 610 mm
Dry weight	588 lb. / 267 kg

The main dimensional drawing shows a principal generator-body length of approximately 34.6 inches, with additional projecting components contributing to the published overall length. Installers should use the correct Westerbeke installation drawing for the generator’s serial number and configuration.

The generator is rated for a maximum continuous inclination of approximately 15 degrees in all directions.

Before installation, confirm:

• Available machinery-space dimensions
• Generator lifting and removal route
• Dry and operational weight
• Mounting-centre dimensions
• Service access
• Sound-enclosure clearance
• Combustion and cooling airflow
• Raw-water inlet position
• Wet-exhaust routing
• Fuel supply and return
• Starting-battery cable route
• AC output cable route
• Remote-control wiring
• NMEA 2000 or Westerlink cable route

Replacing an existing marine diesel generator requires more than matching the kilowatt rating. Voltage, frequency, phase, mounting, weight, cooling connections, exhaust configuration, fuel system, switchboard arrangement, and controls must also be reviewed.
