BOLLARD™ 99kW Marine Generator


Tier 3 marine diesel is fully rebuildable with removable cast iron liners and manifolds with an expected life between overhauls of 40,000-50,000 hrs.

The MGP99 brushless generator delivers full power at exceptionally low winding temperatures. What that means to you is the highest kW per gallon of fuel burn on the market today. Simply put, the BOLLARD™ MGP99 has the lowest cost of ownership of any 99kW generator on the market today.


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 40 to 50 thousand hours.

High-Efficiency Generators
Heavy Duty windings engineered for 80°C rise of 40°C ambient yield extended insulation service life, high electrical efficiency for maximum fuel economy, and superior motor starting at all voltages. PMG dedicated excitation is standard, resulting in even higher motor starting together with 300% sustained short circuit capacity along with VFD and paralleling compatibility.

The BOLLARD™ MG50 –MGP395 Gen-Sets are EPA certified Tier 3 Marine, CARB, EU, and MOC. They meet the lowest emissions levels available on the market today without exhaust after-treatment 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 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 baseframe, and de-noised engine.

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

Controls, Gauges, & Instrumentation
Standard enclosed prewired J1939 digital control panel with key start/stop and run/idle switch. Safety shutdowns are programmed for high water temp, low oil pressure, and over-speed. Included are LED readout of all J1939 trouble codes and diagnostics. Custom panels offer, auto-start/stop function for inverter or paralleling interface, load sharing, digital generator output LEDs and full function electrical distribution switchboards.

Optional SEADRIVE™ Front Power Take Off System
Compact heavy duty housing, pre aligned, easy to install, service friendly, integrated torsional coupling, and available with or without a clutch.
