Phasor KK3-8.5 – 8.5kW Keel Cooled Diesel Generator 60Hz
Commercial workboat fleets operating in sandy shallows rely on this Phasor KK3-8.5 auxiliary generator, generating 8.5 kW at 120V/240V from an 1123cc 3-cylinder Kubota diesel via a closed keel-cooled loop at 470 lbs.
- Grid-cooled closed circuit eliminates raw-water impeller maintenance
- 8.5 kW continuous rating powers commercial deck tools
- Three-cylinder Kubota diesel delivers low-vibration operation
- Automatic shutdown protects against high coolant temperatures

The Phasor KK3-8.5 is a keel-cooled marine diesel generator for vessels requiring 8.5 kW of 120/240V single-phase 60Hz AC power. It uses a Kubota D1005-E4BG three-cylinder diesel engine at 1,800 RPM and a direct-coupled brushless generator with solid-state voltage regulation. This open-frame model is intended for vessels with a correctly engineered closed-loop keel-cooling, grid-cooling, or skin-cooling circuit.
Unlike a standard heat-exchanger generator, the KK3-8.5 rejects heat through the vessel’s external cooling circuit rather than relying on raw water as the primary cooling method. An optional sound enclosure may be available separately. The remote panel provides oil-pressure, coolant-temperature, voltage, and hour-meter monitoring, while automatic shutdown protection responds to low oil pressure and high coolant temperature.
Before Ordering
Confirm required continuous and surge load within 8.5 kW, 120/240V single-phase 60Hz compatibility, adequate keel-, grid-, or skin-cooling capacity, available installation space, structural support for approximately 210 kg, sound-enclosure requirement, diesel fuel layout, exhaust route, ventilation, starting-battery circuit, AC distribution and transfer-switch design, grounding plan, service access, and qualified installation requirements before purchase.
