Phasor JD4-65.0 65kW 1800RPM Diesel Marine Generator

The Phasor JD4-65.0 is a high-capacity commercial marine diesel generator for vessels requiring 65 kW of 120/240V single-phase 60Hz AC power. It uses a John Deere 4045TFM turbocharged four-cylinder diesel engine operating at 1,800 RPM and a direct-coupled brushless generator with solid-state voltage regulation. The base configuration is open frame, with a sound enclosure available as an optional configuration for installations requiring additional attenuation.

The generator uses freshwater heat-exchanger cooling with a raw-water circuit. It includes a deluxe remote instrument panel with engine and electrical monitoring, automatic shutdown for low oil pressure, high coolant temperature, and overspeed protection. This is a high-capacity generator that requires professional load assessment, heavy-duty structural support, substantial ventilation, marine fuel supply, exhaust, cooling, distribution, grounding, and transfer-switch design.

Key Specifications

Electrical Compatibility

This generator is intended for high-demand 120/240V single-phase 60Hz systems. Confirm continuous demand, simultaneous loads, power factor, largest motor-starting surge, distribution architecture, and future expansion before selecting a 65 kW genset. A three-phase alternator option, if required, must be confirmed against the exact model configuration.

High-load vessel systems should use a formal load study that includes air conditioning, watermakers, large battery chargers, refrigeration, pumps, galley equipment, workshop loads, and all other connected equipment. Do not assume the rated 65 kW capacity can support every load operating at the same time.

Installation Considerations

Install the generator on a rigid vibration-isolated foundation designed for approximately 1,077 kg, with safe access for oil, filters, coolant, raw-water pump, turbocharger, exhaust, electrical terminals, and optional sound enclosure. Provide correctly sized diesel fuel feed and return, seawater intake, strainer, wet exhaust, engine-room ventilation, starting battery, AC breakers, grounding, and shore-power transfer isolation. Installation and commissioning should be completed by a qualified marine generator technician.

Before Ordering

Confirm required continuous and surge load within 65 kW, exact 120/240V single-phase 60Hz or approved alternate configuration, available installation space, structural support for approximately 1,077 kg, required sound-enclosure configuration, diesel fuel layout, raw-water intake, exhaust route, ventilation capacity, starting-battery circuit, AC distribution and transfer-switch design, grounding plan, service access, and qualified marine-generator installation requirements before purchase.
