Description

New Paguro 5.5 SY 4.5kW Marine Generator for Sale

If you’re researching the Paguro 5.5 SY price, the Paguro 5.5 SY Generator 5 kVA / 4.5kW Marine Generator is a compact, quiet, and efficient marine diesel generator designed for sailing yachts, motorboats, catamarans, trawlers, liveaboard vessels, and other recreational craft with limited engine-room space. Powered by a proven single-cylinder Yanmar diesel engine, this compact marine genset provides dependable onboard electrical power for essential equipment while maintaining low noise levels and minimal vibration.

The Paguro 5.5 SY is designed for boat owners who need more than a basic portable power source. It is a purpose-built marine generator set engineered to operate in demanding onboard environments where space, cooling, sound control, and dependable electrical output are important. With 5 kVA / 4.5kW of continuous electrical power, the generator can support battery charging, refrigeration, lighting, navigation electronics, water pumps, entertainment systems, and selected comfort equipment when correctly sized for the vessel’s electrical load.

Although some product listings describe this model as operating at 3600 RPM, the manufacturer’s 50Hz specification identifies the Paguro 5.5 SY as a 3000 RPM generator. The exact frequency, voltage, and speed configuration should therefore be confirmed before ordering.

Why Choose the Paguro 5.5 SY?

The Paguro 5.5 SY Marine Generator combines compact dimensions with practical marine engineering. Its small footprint makes it suitable for vessels where engine-room space is restricted, while the soundproof enclosure helps maintain a quieter onboard environment during cruising, overnight anchoring, or extended liveaboard use.

A major advantage of this model is its water-cooled synchronous brushless alternator. The alternator is cooled through a stainless-steel water jacket, helping control operating temperatures without requiring large volumes of cooling air to pass through the acoustic enclosure. This supports consistent generator performance while helping reduce operating noise.

The generator also uses a dual anti-vibration mounting system. Internal soft mounts isolate the engine and alternator assembly, while external flexible mounts further reduce the transmission of vibration into the vessel. This makes the Paguro 5.5 SY a practical low-vibration yacht generator for owners who value onboard comfort.

Its compact construction does not compromise service access. The multilayer GRP soundproof capsule separates into two sections, allowing technicians to reach important service components even when the generator is installed in a confined machinery space.

Quiet and Efficient Onboard Power

Noise and vibration are important considerations when selecting a diesel generator for boats, particularly aboard sailing yachts, liveaboard vessels, and smaller motor yachts where accommodation spaces may be close to the engine room.

The Paguro 5.5 SY addresses this through a soundproof enclosure made from multilayer reinforced material with high-density acoustic absorption and thermal insulation. The enclosure is designed to reduce operating noise while also providing practical access for routine servicing.

The manufacturer lists an acoustic output of approximately 53 dB(A) under its stated test conditions. Actual onboard noise may vary depending on installation quality, exhaust design, ventilation, engine-room insulation, and measurement distance.

The dual anti-vibration system further improves onboard comfort by helping isolate mechanical movement from the vessel structure. Correct installation of the exhaust system, cooling-water circuit, flexible fuel lines, and mounting arrangement is essential to achieve the intended low-noise performance.

Reliable Electrical Power for Boats and Yachts

The Paguro 5.5 SY provides stable AC electrical power for a range of everyday onboard systems. Its synchronous alternator is designed to manage short-duration starting loads, making it suitable for equipment that may require additional current during start-up. The generator provides a listed peak current capability of 60A.

Typical onboard applications may include:

• Battery charging systems
• Marine refrigeration
• Freezers and ice makers
• Interior and exterior lighting
• Navigation electronics
• Radar and communication equipment
• Freshwater pumps
• Small watermakers
• Entertainment equipment
• Galley appliances
• Laptop and device charging
• Selected marine air-conditioning loads

Actual equipment capacity depends on total running demand, starting current, voltage, power factor, and how many appliances operate simultaneously. A complete onboard load assessment should be completed before selecting any yacht generator.

Engineered for the Marine Environment

The Paguro 5.5 SY Marine Generator is designed around the operating requirements of small and medium-sized vessels. The Yanmar L100 is a compact, four-cycle, single-cylinder diesel engine selected for efficient operation and straightforward maintenance.

Marine cooling is supported by a stainless-steel water-to-air heat exchanger and a self-priming cooling pump. Components exposed to seawater are manufactured from AISI 316L stainless steel, helping improve corrosion resistance in demanding saltwater environments.

The synchronous brushless alternator reduces routine maintenance because there are no alternator brushes requiring scheduled replacement. Capacitor voltage regulation supports dependable electrical output, while Class H insulation provides additional thermal protection during operation.

A dedicated 12V / 8A battery-charging circuit supports the generator’s starting battery, helping maintain reliable starting capability when the system is correctly installed and maintained.

Compact Installation and Service Access

The Paguro 5.5 SY is particularly suitable where installation space is limited. Its compact acoustic enclosure allows it to fit into machinery spaces where a larger conventional marine generator may be difficult to accommodate.

Before ordering, confirm:

• Available engine-room dimensions
• Generator service clearances
• Required AC voltage and frequency
• Total continuous electrical demand
• Starting loads of onboard equipment
• Cooling-water intake arrangement
• Wet-exhaust routing
• Fuel supply and return requirements
• Engine-room ventilation
• Electrical cable sizing
• Access for routine maintenance

Proper installation is essential for reliable cooling, low operating noise, safe exhaust discharge, and long generator life.
