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

Don't let rain, snow, or wind keep you in the dark. Consider these options to make sure you get the best generator for your needs.
When the power goes off, the stationary generator goes on—without your intervention. This is great if you travel a lot or have a long commute.
Several portables offer this push-button alternative to the hassle of pull-starting the engine. Just factor in the added cost (around $50) if the battery is not included. Stationary models have automatic starting.
Most portable models run only on gasoline, though some come equipped to run on a propane tank or natural-gas line—or can be converted with kits. Wheels
Believe it or not, some portables price these separately. You could probably move a wheeled generator solo, but without wheels, you'd need help. (All the ones we've tested weigh upwards of 200 pounds.) Wheels can cost up to $150 extra.
Check fuel level at a glance on a portable; this is especially useful during long blackouts.
If oil falls below minimum levels, the generator shuts down to prevent damage. This is usually standard on stationary generators, but it's increasingly common on portables, too.
On some higher-end portables; this provides cleaner power that won't overheat sensitive electronics. Some campsites require it because inverter generators typically run much more quietly.
Four or more lets you best use the wattage by spreading the load, though we recommend using these only for emergency use—or for away uses such as camping. See the next section on transfer switches.
This connects to the generator so you can plug in appliances without running (potentially risky) extension cords outdoors.

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.

Technology offers ability to combine different sized generators; generators with different fuels
Kohler Power Systems has a Mobile Paralleling Box, which delivers cutting-edge flexibility by allowing users to combine different sized generators with different fuel types. The paralleling box is specifically designed for use with Kohler’s gaseous and diesel mobile generator line.
The technology was launched during the 2015 PGA Championship. This product will bring unmatched flexibility and a new level of customization to a wide variety of applications – including large scale, world-renowned events like the PGA golf tournament.
Mix and Match
The Mobile Paralleling Box, along with a fleet of Kohler generators, allows users to mix and match different size generators to meet job requirements. Four of the new boxes can be used to parallel as many as eight generators. The Kohler Decision-Maker 3500 digital controller, which is standard on all Kohler gaseous and Tier 4 Final diesel mobile generators, provides the paralleling intelligence and network communications for remote monitoring.
Any Kohler mobile generator with the Decision-Maker 3500 digital controller will work with the Mobile Paralleling Box.
The digital controller along with the Mobile Paralleling Box makes it possible to parallel generators for applications such as using multiple smaller units to replace a larger generator, providing redundancy to a primary generator in support of critical loads, meeting system capacity demands when one generator is inadequate, or managing generators to be sequenced on or off in a predetermined order based on system output.
One Size Fits All
The new system uses contactors to connect to the bus and eliminates the need for installing or investing in motorized breakers on generators that may never be used in a parallel application. Each contactor is rated at 1,000 amps – different sized generators can parallel as long as each unit’s output is less than 1,000 amps.
The advantage of the paralleling system is that it removes the need to size circuit breakers to specific generator output.
Color-coded camlocks for input and output feeds make the new box easy to setup and maintain while unused camlock connectors are protected with lockable security bars. The system also includes two 25-foot control cables as well as lockable storage for control cables. During the PGA Championship, the Mobile Paralleling Box was used to provide power redundancy for Kohler Co. hospitality tents. A Kohler 175REOZT4 Tier 4 Final diesel unit was used as the primary power source and a Kohler 125REZGT – an EPA-certified gaseous unit that runs on LP – served as a secondary power source.
Advanced Digital Controller
Paralleling intelligence is incorporated into the Kohler Decision-Maker 3500 digital controller, which provides system monitoring and diagnostics while also offering a user-friendly display. The advanced digital controller uses a patented hybrid voltage regulator and unique software logic to manage alternator thermal overload protection features that normally require additional hardware.
Paralleling functions featured on the controller include:

When the lights go out, there is no better feeling than the security provided when your standby generator starts up and restores power to your home or business. Owners purchase a generator for a variety of reasons, whether it is convenience, to back up a business, to run well pumps, or for life safety concerns. Whatever the reason, it is important that an owner feels confident that when the power fails, their generator will operate as intended. Much like a car, a standby generator requires maintenance, and upkeep to ensure it is working at peak performance when you need it the most.
Yearly maintenance agreements
More and more homeowners and businesses are installing generators and seeking companies to maintain them. When storms roll through and cause massive power outages, the demand for service on generators is extremely high. If you have had your generator maintained as part of a regular routine maintenance plan, the chances that it will work for you during an outage arehigh; if you have a problem, however, you will find that companies provide priority service to those customers who have existing maintenance agreements. It's not that companies don't want new business, but it is important to ensure the satisfaction of the loyal customer base a company has already established. Becoming part of that customer base before an extended power outage is the best way to ensure prompt service.
Keep your ears open
One of the easiest ways to identify potential problems with your generator before there is a power outage is by monitoring the weekly exercise. Most standby generators have a programmable exercise timer, where the generator starts and runs for 15 to 20 minutes per week. It is important to know your scheduled exercise time, and what the generator sounds like during normal operation. If you are not at home during the exercise time, you can also check the hour meter and make sure it has advanced each week. Our technicians are happy to provide operator training so you know what to look for. If you notice that the generator has not exercised, a service call can help return it to normal operation before the power goes out.
Look for qualified generator service companies
Servicing generators is a profession that is constantly evolving and proper training is needed to keep up with industry changes. South Shore Generator, for example, currently employs 14 full-time generator technicians, who are factory trained in residential, large industrial, marine, portable and mobile generator applications. Don't be afraid to ask which factories a company represents and which they are qualified to provide
warranty repairs for.
Don't forget about your automatic transfer switch
The automatic transfer switch, commonly referred to as the ATS, is often the brains of the operation when it comes to a standby generator system. The ATS is what senses when normal power fails, signals the generator to start, and transfers the facility load to generator power. It is important to have your service company conduct a simulated power outage during your maintenance, or after repairs, to ensure the ATS and generator are both working properly together.
Investing in a generator is the first step in providing security and peace of mind for your home or business. It is important to remember that once you purchase a generator, you can help make sure it is going to work for you when you need it the most. Proper maintenance, monitoring for weekly exercise and familiarizing yourself with the owner's manual are all important steps toward protecting your investment. Don't wait until you need service in an emergency to look for a service company — yearly maintenance agreements are a great way to move yourself to the top of the priority list.
The compact generators offer reliable power options at greater cost savings
Kohler Power Systems has two compact gaseous-fueled generators to meet growing demand for cost-effective mobile power in new markets. The units can easily switch between optional on-board LP fuel tanks and external LP liquid, LP gas or natural gas fuel sources. The two models (50 kVA – 70 kVA) are part of the industry-leading mobile generator line.
The 50REZGT and 70REZGT are ideal for the event rental, construction, commercial and water utility markets. The compact gensets are engineered to provide reliable power in any situation from disaster recovery and special events to serving as primary power at construction sites and backup power at water utilities, commercial retail and healthcare facilities.
The two models can help reduce users’ fuel costs by 15 to 20 percent* compared to diesel fuel. The propane’s benefits extend beyond affordability.
Propane has become the alternative fuel of choice for an expanding range of residential and commercial applications because of its efficiency and lower emissions. Equipment like Kohler’s mobile generators will give professionals more opportunities to enjoy the benefits of clean, affordable, American-made propane on the jobsite.
Better for the environment
The 50REZGT (50 kVA) features a 4.3-liter naturally aspirated engine while the 70REZGT (70 kVA) features a 5.7-liter engine. The two models feature optional on-board LP tanks, so users working in areas without a propane gas supply can use on-board fuel and then switch to an on-site supply when available. The on-board tank is built for a 24-hour run time, while connection to an external LP or natural gas supply offers extended usage.
In addition to being more cost effective than diesel, LP burns cleaner so these Kohler mobile generators produce fewer toxins and less smog-producing carbon monoxide. LP also flashes to vapor at atmospheric pressure, which reduces the risk of accidents from fuel spills. The gaseous-fueled generators also feature a three-way exhaust catalyst and an electronic isochronous governor. They can be customized with optional add-ons like cam-locks and a voltage selector switch.
Both the 50REZGT and 70REZGT are certified for prime power and standby applications by the Environmental Protection Agency, and certified by the California Air Resources Board, which sets strict air quality standards.
For the Kohler mobile generators, servicing is easier thanks to the company’s patent-pending enclosure, which is easily pulled off after removing some bolts, offering straightforward access to all parts without disconnecting any wires or additional parts. In addition, the mobile generators include a fluid containment system to collect any leaking engine fluids. All Kohler generators come with a standard three-year warranty managed through a service network of more than 10,000 dealers across the United States dedicated to meeting the needs of commercial and residential customers.
The 50REZGT and 70REZGT are available now. Designed with customization in mind, the line offers a choice of fuel, a wide range of engine sizes, and custom receptacle connectors, fuel tanks and paint or decal packages.
