Paguro 5.5 SY Generator 5 kVA 4.5 kW 3600 RPM

Description

Operate compact boat domestic electrical equipment using the Paguro 5.5 SY Marine Diesel Generator. Operating at 3,600 RPM, this single-cylinder 0.435-liter marine diesel power unit produces 4.5 kW continuous single-phase current with 5.0 kVA peak capacity. Built with total water cooling encompassing both engine and alternator, it sustains cabin air conditioning, battery chargers, and water heaters aboard pocket cruisers without cabin temperature rise.

A lightweight cast iron cylinder block integrates an aluminum cylinder head to reduce overall shipboard mass. The internal reciprocating train features a precision ground steel crankshaft, forged connecting rod, and heat-resistant aluminum piston. Engine dimensions highlight an 86 mm cylinder bore, 75 mm stroke, 20:1 compression ratio, 1.4-quart oil capacity, and dry net weight of 215 lbs inside its acoustic sound enclosure. Direct water cooling envelopes the entire electrical stator casing.

Key Features of Paguro 5.5 SY

Sailboat captains buy Paguro 5.5 SY generator packages to achieve total power independence inside tight engine compartments. This 60 Hz single-phase unit fits restricted cruiser spaces to run household appliances at anchor.

• 4.5 kW continuous 120-volt single-phase output maintains small cabin cooling and refrigeration without generator strain.
• Synchronous winding alternator design maintains precise voltage regulation without brush maintenance.
• Sealed fiberglass sound capsule suppresses diesel combustion clatter down to 53 decibels at seven meters distance.
• Paguro 5.5 SY marine diesel generator remote control screen displays real-time voltage, engine temperature, and run hours.
• Full liquid cooling jacket isolates internal engine and alternator surfaces from harsh salt air environments.
• Automatic safety shutdown system halts operation upon high coolant temperature or loss of engine oil pressure.
• Single-side routine maintenance layout places oil dipstick and raw water impeller behind one fast-access door.

Alternator Power Load Capabilities

Governed to a steady 3,600 RPM operating speed, this diesel generator produces clean 60 Hz single-phase power. Continuous electrical output generates 4.5 kW and 37.5 amps at 120 volts. Measured fuel burn records 0.28 gallons per hour at half load and 0.48 gallons per hour at full continuous rating. Pressurized internal oil channels maintain 30 to 50 PSI hot oil pressure, shielding bearing journals during steep offshore sailboat heel angles.

Compact Enclosure Fitment Clearances

The compact sound capsule measures 660 mm long, 460 mm wide, and 540 mm high, sliding into cramped lazarette compartments. Four elastomeric marine mounts cancel engine vibration transfer to stringer beds. A 1.5-inch water-cooled wet exhaust mixer drops gases overboard, requiring four inches of side maintenance clearance.

Essential Marine Maintenance Protocols

Prime fuel passages using the manual primer pump to clear air bubbles before starting the electric starter motor. Fill freshwater cooling loops completely to avoid localized cylinder head hot spots. This generator package is not engineered for non-marine installations, raw seawater engine blocks, or unventilated bilge holds.

• Drain factory break-in oil and install replacement lube filter canisters after the first 50 engine hours.
• Inspect flexible sea water pump impellers and clean fuel sediment bowls every 200 engine hours.
• Descale heat exchanger tube bundles and replace internal protective zincs every 12 months.

Manufacturer Warranty Pack Manifest

Paguro includes a 24-Month limited marine manufacturer warranty on this unit. The wooden freight box contains the complete encased generator package, remote digital start panel, flexible fuel line kit, factory load test printout, and operator maintenance binder.
