Paguro 3 Marine Generator

Description

Cast-aluminum water-cooled sound capsules enclose the Paguro 3 Marine Generator, creating an ultra-compact auxiliary diesel power plant for sailing yachts and small commercial workboats. Delivering 2.8 kW continuous power and 3.0 kVA surge capacity at 120V 60Hz, this generator powers onboard battery chargers, water heaters, and compact galley appliances without taking up valuable storage space.

A single-cylinder 219cc diesel engine powers a direct water-cooled synchronous alternator within an insulated cast-aluminum and fiberglass capsule. Stator coils feature 100 percent copper windings that reject operational heat into an external raw-water heat exchanger rather than machinery spaces. Weighing 154 lbs dry, this ultra-lightweight power unit occupies an exterior perimeter measuring 20.0 inches long by 15.5 inches wide by 18.5 inches high.

Key Features of Paguro 3

Yacht owners who buy Paguro 3 marine generator units acquire ultra-compact commercial power equipment built to fit tight bilge compartments. The full water-cooling circuit covers both engine and alternator, eliminating hot air exhaust inside narrow boat machinery spaces.

• 2.8 kW continuous electrical output powers onboard battery inverter chargers, galley appliances, and water heaters.
• 3.0 kVA peak surge capacity absorbs inductive starting spikes from small refrigeration compressors and bilge pumps.
• Brushless synchronous alternator eliminates carbon brushes and slip rings to minimize periodic maintenance chores.
• Paguro 3 ultra-compact marine design fits into narrow sailboat lazarettes inaccessible to conventional marine power sets.
• Full freshwater cooling circulates through the alternator housing to prevent thermal buildup inside vessel compartments.
• Heavy sound capsule suppresses mechanical diesel knock, maintaining quiet conditions aboard recreational vessels.
• Cast-iron cylinder liner ensures compression integrity across hundreds of commercial offshore running hours.
• Automatic emergency stop circuits halt the engine upon loss of raw-water coolant flow or low oil pressure.

Dynamic Voltage Drop Acoustic Metrics

Generating 52 dB(A) at 23 feet inside its sound enclosure, this generator runs without disturbing crew rest quarters. An integrated capacitor voltage regulator maintains steady 60 Hz electrical output, holding voltage drop within 3 percent under steady electrical loads. The engine absorbs momentary compressor starts from small cabin chillers, burning a modest 0.22 GPH of diesel fuel at half load.

Bilge Placement Siphon Break Specifications

Secure the mounting base to structural stringers above bilge flood lines, ensuring 8 inches of clearance around access covers. Install an anti-siphon valve loop at least 12 inches above the vessel static waterline on the cooling water injection line to prevent siphon flooding. Ground wiring interfaces through an isolated return to prevent galvanic corrosion.

Service Handling Periodic Maintenance Protocols

Unlatching the sound capsule panels provides unhindered access to check oil dipsticks and fuel priming levers. This small diesel generator is not engineered for whole-ship multi-ton central air conditioning, commercial deck cranes, or dry industrial operations.

• Inspect sea strainers for weed blockage and check engine oil before each shift.
• Change engine lubricating oil and replace fuel filter elements every 100 runtime hours.
• Inspect raw-water pump impeller condition and clean air filters every 250 runtime hours.
