- Fail-safe rubber anti-vibration mounts
- Tuned air-intake silencer
- Electronic engine governing
- Remote start-and-stop connection
- Automatic protective shutdowns
- AC output circuit breaker
- One-side serviceability
- Oil-drain hose and drip tray
These features make the 5.5 EGCD a practical yacht generator for new installations and compatible marine generator replacements.
Smooth Three-Cylinder Diesel Engine
The Westerbeke 5.5 EGCD is powered by a naturally aspirated, three-cylinder, four-stroke diesel engine with a displacement of 58.09 cubic inches, or approximately 0.952 litres.
The engine develops approximately 12.4 hp at 1800 RPM and uses a high 23:1 compression ratio, swirl-type combustion system, Bosch-type injection pump, throttle-type injectors, and 12V glow plugs for cold starting.
Its principal engine characteristics include:
| Engine specification | Published value |
|---|---|
| Number of cylinders | 3 |
| Cylinder arrangement | Vertical inline |
| Engine cycle | Four stroke |
| Aspiration | Naturally aspirated |
| Displacement | 58.09 cu. in. / 0.952 L |
| Bore × stroke | 2.99 × 2.76 in. |
| Compression ratio | 23:1 |
| Engine output | Approximately 12.4 hp |
| Rated speed | 1800 RPM |
| Combustion system | Swirl type |
| Governor | Electronic |
| Electrical system | 12V DC, negative ground |
The three-cylinder configuration provides smoother operation than many compact single-cylinder or twin-cylinder generator sets. Combined with its 1800 RPM operating speed and tuned intake silencer, this helps reduce mechanical vibration and air-intake noise aboard the vessel.
5.5 kW Electrical Output at 60 Hz
The standard Westerbeke 5.5 EGCD 5.5 kW produces 5.5 kW of single-phase electricity at 60 Hz.
| Electrical specification | Rating |
|---|---|
| Generator model | 5.5 EGCD-614 |
| Rated output | 5.5 kW |
| Voltage | 120V |
| Rated current | 45.8 amps |
| Frequency | 60 Hz |
| Phase | Single phase |
| Number of wires | Four |
| Power factor | 1.0 |
| Engine speed | 1800 RPM |
| Starting arrangement | Remote |
These ratings are taken from Westerbeke’s official advanced specification sheet. The vessel’s required voltage, distribution arrangement, and switchboard compatibility should be confirmed before ordering.
The generator may support compatible onboard loads such as:
- Battery chargers and inverter-chargers
- Refrigerators and freezers
- Freshwater and seawater pumps
- Navigation and communication electronics
- Cabin and deck lighting
- Electrical outlets
- Entertainment systems
- Small galley appliances
- Selected air-conditioning or refrigeration loads
Actual suitability depends on the vessel’s total continuous load and the starting demand of compressors, pumps, and electric motors.
Electronic Governing for Stable Generator Frequency
The 5.5 EGCD 5.5 kW is fitted with a standard electronic engine governor.
When electrical demand increases, the governor adjusts fuel delivery to help maintain the engine’s rated 1800 RPM speed. Maintaining the correct speed is essential because generator frequency is directly linked to engine RPM.
Westerbeke states that electronic governing virtually eliminates the speed “droop” that may otherwise occur when an electrical load is applied. The published frequency regulation is approximately 0.5 Hz, or 0.6%, from no load to full load.
Stable governing can improve the performance of:
- Battery chargers
- Refrigeration compressors
- Electric pumps
- Navigation electronics
- Communication equipment
- Lighting circuits
- Other frequency-sensitive onboard systems
Correct generator sizing remains essential. Electronic governing improves load response but cannot compensate for a generator that is consistently overloaded.
Brushless Four-Pole Alternator
The Westerbeke 5.5 EGCD uses a brushless, four-pole revolving-field alternator.
Its published generator design includes:
- Brushless construction
- Four-pole electrical design
- Revolving field
- Power take-off interface
- Class H insulation
- Double vacuum epoxy-impregnated windings
- Direct-connected centrifugal cooling blower
- Approximately ±5% voltage regulation
The Class H insulation and epoxy treatment provide additional protection for the windings in humid and corrosive marine environments. Westerbeke also states that the generator’s electromagnetic-interference performance exceeds the requirements of most marine radio telephones and standard televisions.
Because the alternator is brushless, it avoids routine maintenance associated with carbon brushes while supporting reliable long-term electrical production.
Freshwater Cooling with Heat Exchanger
The Westerbeke 5.5 EGCD 5.5 kW uses a freshwater-cooled engine with a shell-and-tube heat exchanger.
Engine coolant circulates internally through the cylinder block, cylinder head, and freshwater-cooled exhaust manifold. Raw water drawn through the vessel’s seawater intake removes heat through the heat exchanger before being discharged through the water-injected exhaust system.
The cooling system includes:
- Closed freshwater coolant circuit
- Shell-and-tube heat exchanger
- Gear-driven raw-water pump
- Coolant-recovery tank
- Freshwater-cooled exhaust manifold
- 45-degree water-injected exhaust elbow
- One-inch raw-water connection
Freshwater cooling supports stable engine temperature and helps protect the internal engine passages from direct seawater exposure.
Routine maintenance should include inspection of the raw-water strainer, pump impeller, coolant level, heat exchanger, hoses, clamps, zinc anodes where fitted, and exhaust-injection elbow.
Self-Bleeding Fuel System
The generator uses a self-bleeding marine diesel fuel system with primary and secondary filtration, a Bosch-type injection pump, throttle-type injectors, and a 12V electric fuel-transfer pump.
The electric transfer pump assists fuel delivery and can simplify priming following routine filter replacement.
Fuel-system installation should include:
- A suitable marine fuel-water separator
- Correctly sized supply and return hoses
- Accessible fuel shutoff valves
- Secure hose support
- Protection from excessive heat
- Clean, uncontaminated diesel fuel
Published approximate fuel consumption at 1800 RPM is:
| Generator load | Fuel consumption |
|---|---|
| 100% load | 0.66 US gal/hr / 2.5 L/hr |
| 75% load | 0.53 US gal/hr / 2.0 L/hr |
| 50% load | 0.42 US gal/hr / 1.6 L/hr |
| 25% load | 0.34 US gal/hr / 1.3 L/hr |
Actual consumption will vary with generator condition, installation, ambient temperature, fuel quality, and connected electrical demand.
Remote Starting and Safety Protection
The Westerbeke 5.5 EGCD 5.5 kW includes an instrument panel with a safety-stop switch and a plug-in connection for remote starting and stopping.
Standard protective shutdowns monitor:
- Engine overspeed
- Engine underspeed
- Low starting-battery voltage
- Low engine-oil pressure
- High exhaust temperature
- High engine-coolant temperature
The generator also includes an AC circuit breaker and a 50-amp, 12V battery-charging alternator.
These protections help shut down the generator when potentially damaging conditions are detected. They do not replace regular checks of the oil level, coolant, raw-water flow, exhaust system, belts, fuel supply, and electrical connections.
Full-Torque Power Take-Off Interface
A useful feature of the 5.5 EGCD 5.5 kW is its full-torque power take-off interface.
With a correctly engineered customer-supplied electric clutch and hydraulic pump, the interface may be used to power compatible auxiliary systems such as:
- Bow or stern thrusters
- Hydraulic winches
- Compressors
- Emergency propulsion or “get-home” systems
- Other approved hydraulic accessories
The complete hydraulic installation must be properly engineered so that the attached load does not exceed the generator engine’s available power or interfere with normal electrical production.
Quiet 1800 RPM Operation
The 5.5 EGCD 5.5 kW is designed for smooth, relatively quiet operation through the combination of:
- Three-cylinder engine balance
- Low-speed 1800 RPM operation
- Tuned air-intake silencer
- Fail-safe rubber anti-vibration mounts
- Freshwater-cooled exhaust manifold
- Water-injected exhaust system
Westerbeke describes the model as providing three-cylinder smoothness and quiet, slow-speed operation.
Final onboard noise levels will also depend on the vessel’s:
- Machinery-space insulation
- Generator foundation
- Ventilation openings
- Wet-exhaust layout
- Muffler selection
- Hose and cable support
- Structural vibration transmission
