How to Choose a Marine Generator

A marine generator will keep the current flowing to all of your electrical equipment on your boat

Marine generator

Today’s sport-fishing boats brim with power-hungry electrical equipment, from air conditioning to audio systems, spreader lights to live-bait pumps, refrigerators to radars and microwaves to water makers.

Supplying enough current for all of these accessories can pose a challenge, particularly on extended trips to fish remote waters with few marinas and no shore power. One option is to run the main engines to keep power flowing to the AC/DC system. Yet fumes, vibration, noise and fuel consumption render this practice annoying, especially on anchor or tied to the dock.

A quiet-running marine generator offers a more pleasing solution. Whether you’re adding, upgrading or ordering a new boat, consider these factors when choosing among the many brands and models of gensets.

If adding a genset, think about location. Generators go below deck, often in the engine room or an aft compartment. Determine how easily you can access the space for installation and maintenance, as well as how the new unit will affect weight distribution.

On boats less than 30 feet in length, fitting in a genset could prove impossible. In these cases, a portable marine generator might be your only option.

Fuel of Choice

For convenience, choose a genset that operates on the same fuel as your boat. For example, with gasoline inboards, select a gasoline genset so you can tap the main tank.

There is one possible exception. On an outboard fishing boat, which runs on gas, it’s sometimes wise to have a diesel generator. Outboard boats rarely feature ventilation for below-deck compartments. Diesel (less volatile than gas) is safer to use in such enclosed spaces. You’ll need a separate diesel tank, so account for that when evaluating available space. If adding a genset, you’ll also need to customize a system to usher air to the generator.

Most large sport-fishing boats usually have diesel inboards, so a diesel generator makes the most sense. Whether you choose gas or diesel, a separate canister-style fuel filter helps ensure delivery of clean, water-free fuel to the genset.

Output Options

Marine generators are rated by kilowatt output — from as little as 3.5 kW to as much as 200 kW. To determine the right model, add up the power needs for the accessories you plan to run. Then select a genset with about 20 percent more output than your total requirement.

Resist thinking that more is better. A genset running at insufficient load leads to carbon buildup and other complications. On the other hand, don’t run all of your accessories at once. A genset operates best when carrying 35 percent to 70 percent of its rated load.

Installation Details

Gensets are water cooled, so when adding a unit plan on installing a water intake with a strainer to keep debris from clogging the cooling system. Also, you’ll need plumbing for cooling water to exit overboard.

Most gensets come with remote ignition switches and basic gauges for installation above deck — usually near the helm or in a cabin — and a second control panel on or near the genset.

Quiet and Clean

Thanks to insulating shields, isolation mounts, mufflers and underwater exhaust, marine generators are quieter than ever. Carbon monoxide (CO) is a concern, especially with gas generators. Yet companies such as Kohler (www.kohler.com) now make low-CO gasoline generators with lower emissions. The Kohler Low CO models feature self-monitoring systems that shut down the generator if CO builds to dangerous levels.

As the electrical demands of today’s sport-fishing boats grow, so too does the need for a convenient way to keep the current flowing. Today’s gensets deliver, whether at the dock or far from the marina.

Add a Portable Generator to Your Boat and Expand Your Boating Options

Joseph Coupal - Tuesday, May 16, 2017
South Shore Generator - Kohler Marine Generator

When mariners gather for a discussion about all things boating, a topic that often comes up relates to generators. The generator discussion usually reveals some level of confusion among participants. Some are confused about how powerful their generators should be for their type of boating. Others have concerns about noise and fuel consumption, while still others are concerned about pollution. All of these concerns are legitimate.

Like any other piece of boating equipment, the choice of size and type of generator depends on how it is to be used. If the plan is to take it to the beach to provide power for a sound system or to keep the drinks cold, any number of small, portable gasoline units weighing as little as 50 pounds are available. There are many well-built players in the marine generator market. Research—an indispensable boating skill—will help locate and price these units in any skipper’s local area. Many of these small units are as quiet as the inside of a library—about 60 decibels—and they are so light and small they can easily be carried on all but the smallest boats. Many small boats have them on board as a safety item to provide emergency battery charging, since almost all of them are capable of producing direct current (DC).

If the generator is going to be used to power tools that are part of a vessel’s repair or maintenance system—such as a welding machine on a metal boat—the smaller portable units will generally not do the job. Any generator with an output of at least 5kW will be required if it is to be used as part of the repair and maintenance system of the boat, and it will not produce enough power to run all repair tools at the same time. However, it is perfectly adequate if the person doing the repairs is prepared to use one, or at the most, two power tools at the same time.

A generator of 12.5kW will produce the same power as is usually found in a small land-based home or condo and will generally enable all normal and regular electrical equipment to be operated at once. Larger boats, particularly those equipped with multiple chillers for air conditioning, or electric stoves, ovens, and refrigeration, should be looking at generators capable of producing 15-20kW.

In the past, smaller boats in the 25 to 30-foot range were simply not big enough to be able to carry the weight of an onboard built-in generator system. Similarly, gasoline-powered boats could not have onboard generators due to safety concerns because of gas fumes. However, in recent years a number of small diesel-powered generators have made their way onto the market. Some of them are referred to as “ignition proof” in that their operation will not trigger a gas fume explosion if installed in older gasoline-powered boats. They also have the advantage of being relatively lightweight. Many produce small output, diesel-powered generators in the 2.6 to 4kW range that are useful in even the smallest vessels. Not only do these smaller units provide power for 110V AC tools and equipment, they can keep batteries topped up through various available battery chargers.

With the ever-increasing availability of lithium ion batteries that can be charged very rapidly without adverse effects, generators that produce three-phase power are coming onto the market. These units can produce enough power to charge (through a special charger) a set of lithium batteries in a faction of the time single-phase power can do the same job. Standard appliances don’t like three-phase power, however. A number of smaller generators offer a three-phase option. Another option most of the manufacturers are now making available is a generator with Direct Current (DC) output. These units produce battery-charging power for vessels using an inverter to produce AC current from an onboard battery bank.

Any skipper who is considering adding a new generator to his boat should spend some time determining exactly what his electrical load is likely to be. All electrical appliances have the power requirements listed on the nameplate or electric motor. The power requirement will be listed in watts. When on full, electric heaters, refrigerators and freezers usually require 1,500 watts—to run them all at the same time will take 4.5kW. Don’t forget about a microwave, electric cooktop, water heater, and electronics. After all appliances and systems are examined and the skipper factors in how the electrical system will be used, the total power requirements will be determined and a decision on the type and size of generator can be made.

Updating Your Marine Generator Can Pay Off in Many Ways – Wareham, MA

Joseph Coupal - Monday, April 17, 2017
South Shore Generator - Kohler Marine Generator

New generators use less fuel, burn cleaner, and produce more power than their predecessors.

As the season nears, it’s a good time to assess any needs or shortcomings your boat might have. The engines were serviced and they’re purring like proverbial kittens. New props were installed and you managed not to ground them. The electronics are current, even the canvas looks brand new. But what about the generator?

Like an insurance policy, or even a loyal deckhand, many of us take the generator for granted. It always kicks on when we need it and provides much-needed juice for the myriad appliances many boats now carry.

Updating your boat’s generator can pay off in a number of ways. The latest and greatest models finally utilize electronic fuel injection to improve efficiency and reduce the output of carbon monoxide.

A control pad makes for simple operation.

Generator sizes are based on their output. The amount of kilowatts they produce is usually the number in the model name. Kohler is one of the manufacturers making low-CO generators, which reduce carbon monoxide emissions, making it safer and more comfortable to be aboard a boat while the generator is running. The Kohler uses throttle-body injection.

Kohler has its own small-footprint diesel model gensets starting with the 490-pound, three-cylinder 6EKOD, which produces 6 kW and offers sophisticated functioning and touchscreen interface. It fits in a 31- by 21- by 22-inch envelope, which should save space in your engine compartment. The 9EKOZD is also powered by a three-cylinder diesel and produces 9 kW. It fits into a 34- by 21- by 22-inch space and weighs 548 pounds. Finally, the 11EKOZD is an 11-kW model based on a four-cylinder diesel engine, weighing in at 616 pounds. Each Kohler genset is available in 50- or 60-hertz models and comes with advanced controllers that provide trouble-free operation. The new touch-style control pad has power and start/stop buttons, a two-line, 12-character display, and a simpler setup process. There’s even a USB port for quick software installations and maintenance downloads. The controller has power management, a fuel primer, a hybrid voltage regulator, and an interface with SmartCraft instrumentation.

If you’re wondering if you need a generator or you can still get by with an inverter, most experts say that if your electronic accessories require more than 3.5 kW, you need a generator. Add up the power requirements for each appliance you plan to run off the generator. Once you arrive at a total in kilowatt-hours, choose a generator rated to produce at least 20 percent more.

Trying to go cheap with a genset rated too close to your total will cost you in the end. Your new generator will wear out quickly and you’ll wind up buying the correct size replacement unit sooner than should be necessary. Don’t go off the deep end in the other direction either. Using an oversize genset runs the unit at an insufficient load, which will cause it to operate inefficiently, which increases fuel consumption. A generator should run at least at 25-percent load with the ideal being 35 to 70 percent.

Finally, if you like to take longer cruises, install a remote canister-style fuel-water separator in-line for your generator. Most gensets come with a small integral fuel-water separator, but the remote version can save you some headaches by preventing contaminants from getting to that smaller filter because it will clog quickly. Position the remote separator ahead of the motor in the hose routing and make it accessible so you can change the element or clean it out if it gets clogged.
