It’s time for you to get the best boat oil extractor. But you cannot just pick one randomly from the market, can you?

The essence of this article is to introduce you to 5 best oil extractors so that you can easily pick the best one for yourself.

1. EWK Pneumatic/Manual Fluid Extractor (Top Pick)

You cannot go to the marketplace to have the best boat oil extractor without considering EWK. This is indeed a great extractor with many functionalities.

Its top feature is that it has both manual and pneumatic features. If you don’t have a compressor with you, you don’t have to worry about getting stranded and start working with your hands.

The pneumatic model provides you high-speed oil extraction, but if you have no compressor to use nearby, the manual feature saves the day.

With solid construction, it changes oil pretty quickly. As the tank is stout, it's able to get plenty of suction. During the pneumatic mode, its extraction speed is almost 1.6 liters per minute, using 140 psi.

On the other hand, if you are manually extracting, it won’t take you more than 8 minutes to fill 6 quarts of oil. On average, this fluid extractor can clean the oil tank within 5 minutes only.

Moreover, the device has a safety cup and three interchangeable nylon tubes. The nylon hoses provide a great touch while the safety cup and the valves are essential to stop the extraction process. The safety cup helps reduce the spilling to almost zero, which is great if you don’t want a greasy looking extractor.

Also, the whole system is amazingly engineered and very easy to use and handle. This oil extractor from EWK can be used for most land vehicles too. As far as tools go, this one will clearly be a good investment for your vehicle.


  • Has two extension hoses
  • Both pneumatic and manual pumping
  • Fast evacuation speed
  • Safety cup to reduce spilling


  • The primary suction line could be much longer

2. DasMarine Oil Extractor (Cheap Option)

This brand is suitable for both home and personal use. We actually love this compact size even though it has almost zero capacity for storing the lube. One of the reasons being, it creates no hassle to carry it around whenever needed due to its very small size.

You’ll need an extra oil tank when you suck the oil out. Just place the inlet tube inside the dipstick holder and the outlet hose into an external container. As this is an electric oil extractor, you’ll need to connect it to your boat’s battery. The extractor makes some extra noise if it doesn’t get to pump sufficient oil.

And the motor is fairly powerful with an input voltage of 12 DC and 60 watts. With that, it can transfer almost 1 liter of oil per minute. One great thing about this extractor, which most others seem to miss, is the length of the hose or tube. It is of the perfect size and length.

Moreover, this oil extractor from DasMarine is by far the easiest to use. Made out of lasting plastic and aluminum, it is one of the sturdiest oil extractor pumps there are. If you want to drain a great amount of oil on a regular basis, we suggest you consider this one.


  • Easy to use and light
  • Automatic operation mode
  • Long hose pipe
  • Energy-efficient engine


  • Makes noise while sucking oil

3. Qiilu Fluid Pump Extractor


The Qiilu oil extractor looks a lot like the one we’ve just discussed from DasMarine. It is an ideal tool for quick and clean oil changes for your boat. This high-efficiency oil pump is great for various fluids and oils.

When it comes to versatility, durability, and peak performance, the Qiilu fluid extractor comes at the forefront. This is easily one of the best electric oil extractors for a boat. It will facilitate the quickest and cleanest extraction for you. And it is quite easy to use too!

Once you connect the power clamps to your battery, simply turn on the power switch, and it starts its job. One small tip, try to stick the outlet tube to the oil container with a vise-grip clip so that it doesn’t spill oil outside.

An important feature to take advantage of is that this extractor is really versatile. Not only can you use it to extract oil from your boat but also from any other land vehicle too. It works great for motorcycles, vans, quads, cars, and any 12v vehicle.

This tiny machine is suitable for most lubricants, including oil, diesel, etc. However, never use it to suck petrol as it isn’t suitable for it. The Qiilu boat oil extractor is made with plastic and aluminum, making it tough and hardy yet light to carry.

Its powerful motor can pump approximately 150 liters of diesel per hour. But, we suggest not to use it over 30 minutes without giving it a rest to cool down a bit.


  • A dipstick bore given for oil extraction
  • Perfect tube length
  • Powerful motor for pumping oil


  • Doesn’t come with a fluid tank

4. OEMTOOLS Manual Oil Extractor


Okay, this is the most good looking oil extractor we have seen. With a single-piece construction and brilliant black and white color, this manual gear oil extractor makes fluid extraction look fun.

If you are concerned about oil spillage, transmission, and safety, then this is the safest machine you can use. One of the drawbacks of most manual oil extractors is their failure to include an automatic shut-off valve, but Oemtools, in this case, nails it. So, you have no fear of oil spillage during extraction.

The Oemtools oil extractor is simply a great relief if you want to drain out the oil in the old fashioned way. Designed for you to enjoy a complete mess-free and stress-free evacuation, this will drain out all the lube necessary.

Using this extractor is also very easy with two specialized dipstick adopters, and one five-foot flex hose. The overflow protection that you get from the shut-off valve ensures zero spillage of fluids. It is also made as one-piece so that there is no gap through which fluid can spill out.

It also comes with a 1.4 gallons reservoir that provides large enough space for draining fluid from multiple engines if necessary. This amount of storage capacity ensures great efficiency. Additionally, the five feet flex hose allows smooth operation.

What we liked most about this extractor is its versatility. Because you can use it to drain fluid, extract oil, and another low viscosity coolant like water.

Another impressive thing is the oversized handle, making it easy and wide enough to accommodate comfortably the grips of any user. It doesn’t matter if it is the first time you’re using an oil extractor since this unit has been made very easy to operate and handle.

Not everyone is ecstatic about pumping oil manually with their hands. It takes a person a little bit of strength and pressure to create the vacuum inside the extractor. But this oil transfer pump runs with electricity, which means you can connect it with the battery of your boat, car, a generator, or any other power source.

With a powerful motor, this can handle a maximum pressure of 0.8 MPA, which results in a transmission of 4 liters of fluid per minute. This is more than any of the oil extractors we have discussed so far. If you are in a constant move, this 12V pump can serve you correctly.

What to Look for before Buying?

When you visit the marketplace, you’ll notice many types of oil extractors, each claiming to be the best. But that excessive hype doesn’t always carry the truth. So, you must know what really matters in the best oil extractor for boats.

Three Primary Categories

First, you must know and understand there are three primary types of oil extractors: manual, pneumatic, and electric extractors.

Manual Extractors

As the name suggests, this doesn’t require an electrical connection and needs you to pump it with your hand to create the vacuum for the pump.

Pneumatic Extractors

By connecting to an air compressor, this type of extractors suck the oil out of the engine. It also has some manual side to it.

Electric Extractor

These are a bit costlier but are more efficient for sucking out the oil clean. It gets the electricity from the vehicle's energy source, battery.

Important Features to Consider

Important Features to Consider

When you invest in a boat oil extractor, let it have the best return for the money. Look for the following features to get the best outcome.

Convenient Size

For ensuring efficiency and to reduce time consumption, look for a size big enough to drain the tank in one go but not too big to handle.

Usually, the capacity of the reservoir ranges from 1.5 liters to 100 liters. If you are using it for personal use only, we suggest not to go over 10 liters capacity.


Mind that the fluid you’ll be extracting is harmful to sensitive human skin and body. Try to obtain those extractors with additional safety features, including automatic shut-off valve and multiple suction pipes.


When you’re using the oil extractor for your personal use, compact size works the best. Smaller the size means lesser in weight and easier to carry around when you’re out.

But if it is needed for commercial purposes, then those massive setups require larger sized extractors for fast and efficient cleaning.

Frequently Asked Questions

Here we have some of the most commonly asked queries regarding the best oil extractors:

1. How does an oil extractor work?

Oil extractors work using the principle of air vacuuming. It creates a vacuum inside the module, which sucks the fluid at one end of the tube and emits that fluid at the other end.

2. Why should I use an oil extractor?

It saves you a great amount of time, frequent visits to the auto shops, and a good sum of money in the long run. They come in handy during emergencies.

3. What is the best way to clean an oil extractor?

You can clean the exterior of your boat oil extractor with a wet cloth or hot water. But to clean the inside of the unit and the hoses, you should use alcohol.

Hot water, however, cleans the interior as well, but sometimes won’t dry off causing the oil afterward to be emulsified. Alcohol, on the other hand, evaporates easily.

4. Can oil extractors be used to pump gas tanks?

These extractors are rated to transfer oil, diesel, and sometimes water but not gasoline. Gasoline releases vapors, which might leak out around the motor, making dangerous ignition or explosion.

5. How long does an oil extractor last?

It depends on how much you use it and take care of it. Even if you are using it on a regular basis, keeping it clean from time to time will make it last at least five years. Sometimes it lasts longer with minor changes like tubes and hoses.

Take Away

We want to reiterate to you that a good oil extractor will always save you a lot of time, energy, and money in the long run.

So to make your life easy, we tried our best to pick the best oil extractor for boats with the best quality and highest efficiency.
