Overview Phasor LP1 3.5 kW Marine Generator 120/240V
The Phasor LP1 3.5 kW Marine Generator 120/240V is a 60 Hz marine diesel generator built with a Kubota EA300NB engine and Sincro electric end. This model is designed for buyers who want a clearly specified 3.5 kW unit with 120/240V output, slower 2800 RPM operation, and core protective features such as automatic shutdown for low oil pressure and high coolant temperature.
Its build includes a freshwater heat exchanger cooling system, a heavy duty syncro-cogged timing belt drive system, four point stainless steel isolation mounts, and a stainless steel water cooled exhaust riser. Phasor also uses a single circuit control system with no printed circuit boards or relays, which may appeal to buyers looking for a more straightforward mechanical setup.

Applications
This generator is suited to marine buyers looking for a compact diesel-powered onboard generating unit with verified 3.5 kW output and 120/240V, 60 Hz electrical specifications. It may also fit projects where buyers prioritize slower operating speed, mechanical simplicity, and clearly listed service parts over unnecessary added complexity.
Why Choose This Marine Generator
The LP1 stands out for its clear model identity and practical specification set. You get a Kubota diesel engine, Sincro electric end, freshwater heat exchanger cooling, integrated shutdown protection, and a spare parts kit that adds useful service items from the start. Phasor also lists a limited 5 year warranty, which adds confidence for buyers comparing compact marine diesel generator options based on confirmed product details rather than broad marketing claims.
Another practical point is the stated connection data, dimensions, weights, and service-related hardware. Buyers can review line sizes, exhaust diameter, operating speed, and dimensional references with or without soundshield, while also noting that the 4 Gauge remote panel will not work with this generator.
