About Marine Generators

Marine generators are indispensable for delivering power to boats, ships, yachts, and other watercraft on the water and away from the shore. Fishing operations, oil and gas companies, cruise ship lines, marine biologists, and countless other entities rely on marine generators for consistent, reliable electricity for onboard systems and appliances when shore power is unavailable.

The terms “marine generator” and “marine genset” are sometimes used interchangeably, but they aren’t the same thing. A marine genset refers to the entire system, which includes the power generator, diesel or gas engine, alternator, control system, and other components.

Why Do I Need A Marine Generator?

Marine generators deliver steady power—often under demanding conditions related to saltwater and high heat and humidity levels—that keeps essential electrical systems running smoothly. These include navigation equipment, communication systems, lights, heating and cooling systems, and appliances.

Note that some marine generators can provide backup power, proving handy during power outages and emergencies.

Marine Generator Fuel Types

Marine generators typically run on gasoline or diesel, but these generators are far more fuel-efficient than the watercraft’s main engines. Due to the volatility of gasoline and the prevalence of diesel-powered marine engines, diesel marine generators are the more common type.

You’ll also find hybrid marine generators that employ an electric motor, batteries, and traditional diesel engine. Benefits include greater fuel efficiency, quieter operation, and less costly ongoing maintenance.

The Range Of Marine Generators

Marine generators are primarily distinguished by their rated electrical capacity, measured in kilowatts (kW). You’ll find various power outputs available from marine generator manufacturers. Models in the 3.5-kW neighborhood are well-suited for smaller boats, and larger units exceeding 1,000 kW are ideal for cruise ships, container ships, and other large commercial vessels.

How To Buy A Marine Generator

Marine generators typically have durable designs that can withstand the intense vibrations, water, heat, and other elements they may face. Built for long-term, ongoing operation, they also use noise-reducing components and corrosion-resistant materials like stainless steel and aluminum.

Marine Generator Buyer’s Checklist

Before you buy a marine generator: 

• Make sure its capacity meets your electrical requirements
• Ensure your boat can handle the unit’s size and weight 
• Consider units that use the same fuel type as your vessel 
• Check that crucial alarm and/or monitoring systems are included
