The best small marine diesel generator is one that will fit your needs. Whether it be for commercial, residential, or recreational purposes, there are many different generators to choose from.
It’s essential to understand the difference between a permanent and portable generator so you can make an informed decision when shopping.
This blog post will give you all the information you need to find the perfect little workhorse for your boat. Here’s a highlight of the 3 top Marine Generators.
The Importance of Having a Marine Generator Onboard
A small marine diesel generator is an excellent addition to any boat.
It will give you peace of mind knowing that your watermaker, lights, and other appliances can run even when there’s no shore power available.
In commercial applications, it may be required by law for some boats but in general, having a backup system onboard is always intelligent, especially if you spend a lot of time on the water.
Types of Small Marine Generators
There are two main types of small marine diesel generators that you should be aware of before making any purchases. They include:
1. Permanent Generators
A permanent generator runs off the engine powering your boat.
It can produce enough power for most recreational uses, but it may not hold up to more extensive demands or if there is a lot of demand for power at one time.
2. Portable Generators
The second type of generator is a portable unit that can be easily removed from the boat and used on land.
These are great for use in remote locations where you need to power more than just your boat, but they aren’t always equipped with features needed for more expansive or marine environments.

Best Small Marine Diesel Generators Buying Guide
When you are ready to purchase a small marine diesel generator, there are several factors that you need to take into consideration. These include:
1. Type of Generator
Smaller generators can be either portable or permanent, so make sure that you pick the best one for your specific use case and needs right now and in the future.
2. Wattage of Generator
The wattage is the overall capacity that the unit has, so you need to make sure that your generator can handle all of your equipment at once and what you might add in the future.
The higher number here isn’t always better because a lower wattage with multiple outlets may be better for your specific situation.
3. Fuel Type
Depending on where you are boating, it may be easier to use gas or diesel as a fuel source.
Diesel generators tend to have more power but are also larger and heavier than their gasoline counterparts. Gasoline is cheaper, so if budget is an issue, this might be the best option.

4. Generator Brand
You may have heard of particular brands and wanted to stick with them, but it is a good idea to look at all of your options before making a final decision.
Some generator manufacturers offer better warranties, while others are known for their overall quality over time. Make sure that you do some research to find the best brand for your needs.
5. Price
The price is an essential factor in buying any equipment, but you should also consider how much use you will get out of the generator before making a final purchase decision.
Think about what features are essential and if they are worth spending more money on to get them. If you are looking for something to use on the weekends, a less expensive generator might be best.
At the same time, if you want one that can handle more frequent usage or have additional features to maintain easily, then it may make sense to invest in a higher-quality option.
How to Make the Most Out of a Small Marine Diesel Generator?
There are a few things that you should keep in mind when using your small marine generator. They include:
- Always make sure to use the right oil for your engine and check it frequently – this will ensure maximum performance from your machine.
- Ensure to let the unit cool down before storing or transporting it, as this will also help increase the unit’s lifespan.
- Use your generator for short periods and never leave it on if you are not using it, as this can cause damage to the engine over time. This is especially important in marine environments where there are large fluctuations in temperature that could be harmful to your machine.
- Read the manual thoroughly before using your generator for the first time. This will help you avoid any damage that can be done to it if not used properly.
