BOLLARD™ 9kW Marine Generator

High-efficiency compact generators with dedicated secondary excitation windings for unsurpassed voltage control.

BOLLARD™ 9kW Marine Generators are built with Isuzu 3CH1 engines and EPA certified Final Tier 4, CARB, EU, and MOC.


Unsurpassed Quality & Reliability
BOLLARD™ Generators are designed and built in the USA specifically for the rugged conditions of commercial use. The expected time between overhauls on the BOLLARD™ packaged generator set is 20 to 50 thousand hours.

High Efficiency Generators
Heavy Duty windings engineered for 80 deg. C rise of 40 deg. C ambient yield extended insulation service life, high electrical efficiency for maximum fuel economy, and superior motor starting at all voltages. Dedicated auxiliary excitation windings are standard, resulting in even higher motor starting together with 300% sustained short circuit capacity in a unique compact design.

The BOLLARD™ MG-9-12.5 Gen-Sets are EPA certified Final Tier 4, CARB, EU, and MOC. They meet the lowest emissions levels available on the market today without exhaust aftertreatment resulting in reduced maintenance and operating costs while preserving our clean air and water quality.

Keel Cooling, Heat Exchange, or Radiator Compatibility

Premium Marine Grade Protection
BOLLARD™ generators feature Imron™ 2 part marine epoxy overcoats on the engine, generator, and base frame. Accessory brackets are typically powder coated, and fasteners are primarily stainless steel to protect your investment from the harsh marine environment.

Heavy Duty Air Intake Filtration & Silencing
For increased performance, extended engine life, and quiet operation.

Heavy Duty Structural Steel Base Frame & Reduced Noise
For ease of installation, added structural integrity, safety and durability. Superior vibration and noise dampening with a high mass flywheel, polyurethane vibration isolators, mass loaded & stiffened base frame, and de-noised engine.

Water Jacketed Exhaust Manifold and Expansion Tank
Provides low engine room temperatures and greatly reduces fire hazard.

Controls, Gauges & Instrumentation
Standard enclosed prewired digital auto-start control panel with push button start/stop. Safety shutdowns are programmed for high water temp, low oil pressure, and over-speed. Included are LED readout of oil pressure, engine hours, DC system voltage, water temperature, engine speed in RPM, Generator Voltage and Frequency. Custom panels offer, auto-start/stop function for inverter or paralleling interface, load sharing, digital generator KW output LEDs and full function electrical distribution switchboards.
