EWK Oil Extractor

The Top Oil Extractor for Boat

If you're looking for an oil extractor for a boat but don't have the time to do your own research and to compare prices, then go for the EWK Pneumatic/Manual Oil Extractor Pump. 

It's the most powerful one among all. Suitable for most occasions.

Draining out oil in the traditional way can be a time consuming process.

A better approach is to have your own oil extractor in case of emergency. A boat oil extractor can keep your boat clean without all the hassle.

The right boat oil extractor is perfect for removing all kinds of fluid, including engine oil, coolants, transmission fluids, and gear oil.

Any engine that uses oil will work much better after cleaning and replacing the fluid.

If you own a boat with a great oil extractor, you can handle DIY projects on your own. With it, you can also efficiently drain the engine while saving a lot of money that would normally be spent on servicing.

Top 5 Oil Extractors for Your Boat

If you're in need of choosing the right boat oil extractor, it may not be wise to just pick a random oil change pump from the Internet. 

Here are 5 of the best oil extractors so that you can easily pick one that will meet your needs.

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

EWK is one of the top oil change kits on the market today. This is indeed a great extractor with many functionalities.

Its top feature is that it has both manual and pneumatic options available. If you don’t have a compressor with you, you don’t have to worry about getting stranded without the tools you need.

The pneumatic model can do high-speed oil extraction by using a compressor. But if you have no compressor with you, the manual hand pump feature can definitely save the day.

The unit is built solidly and it changes oil very quickly. With such a stout tank, it's able to get plenty of suction. In pneumatic mode, its extraction speed is almost 1.6 liters per minute, using 140 psi.

If you are using the manual extraction method, it won’t take you more than eight minutes to fill 6 quarts of oil. On average, this fluid extractor can clean the oil tank in about five minutes.

This device also 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 included in the kit helps reduce the spilling to almost zero, which is great if you don’t want a greasy looking extractor.

Also, the whole oil change system is amazingly engineered and very easy to use and handle. This oil extractor from EWK can be used for most land vehicles too.

When it comes to essential tools for your boat, this one will clearly be a good investment and vehicle in the long term.

For most people, this one is the right choice, but it's not cheap.

If you are looking for a less expensive option, check the third one we mentioned. That one is good enough for occasional use. However, it's not as powerful or as rugged. If you have the money, we recommend you go with the EWK.


  • 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. OEMTOOLS Manual Oil Extractor (Runner Up)

This extractor from OEMTools is the best looking one we've seen.

The difference between this one and the one from EWK is that it only has a manual operation feature. 

However, this one is more than just an oil extractor. It can easily remove engine oil, radiator fluid, transmission fluid, water, and more. It's suitable for most light and heavy duty vehicles and boats.

With a hardy, single-piece construction and brilliant black and white color, this manual gear oil extractor makes fluid extraction look fun.

If you are concerned about safely extracting oil and transmission fluid, then this is one of the safest machines you can use.

One of the drawbacks of many manual oil extractors is their failure to include an automatic shut-off valve. This isn't the case with OEMtools, and they absolutely nailed it. So, you have no fear of oil spillage during extraction.

The OEMTools oil extractor is simply a great option if you want to drain liquids from the gear pump in the old fashioned way.

Designed for you to enjoy a complete mess-free and stress-free evacuation, this will drain out all the liquids you've got.

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 fluid spillage. It is also made as one-piece so that there is no gap through which fluid of any temperature can spill out.

It also comes with a 1.4 gallon reservoir that provides large enough space for draining fluid from multiple engines if necessary. This helps you get more done in less time than with some other models. 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 comfortably accommodate the grips of any user.

It doesn’t matter if it's the first time using an oil extractor, or you've done it many times. This unit is extremely easy to operate and handle.

If you don't need a pneumatic operation option, and you're OK with manual, then go for this one. 


  • It features a 1.4 gallons fluid capacity
  • Provides a shut-off valve
  • Large handle for a comfortable grip
  • Leak-proof single-piece structure
  • Versatile to extract all kinds of fluids
  • Can be used for various purpose 


  • Length of the dipstick tube is a bit short

3. DasMarine Oil Extractor (Cheap Option)

This brand of pump kit is suitable for both home and personal use for any type of vessel. We actually love this compact size even though it has almost no capacity for storing oil.

Since it's so small, it's incredibly easy to carry around or to fit in almost any storage area.

Unlike the first one we mentioned, if you buy this one, you’ll need an extra oil tank to store the oil. Just place the inlet tube inside the dipstick holder and the outlet hose into an external container.

Since this one is an electric oil extractor, you’ll need to connect it to your boat’s battery, and it will require minimum effort on your part. Also, the oil change pump will make 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 oil change kit, which most others seem to miss, is the length of the hose or tube. This one has the perfect size and length.

This oil extractor from DasMarine is by far the easiest to use. Made out of lasting plastic and aluminum, it is also one of the sturdiest oil extractor pumps there are.

If you only drain oil occasionally, then we suggest you consider this one. It's a good value, works pretty well, and is easy to use.

Just keep in mind that you get what you pay for, and don't expect it to be quite as durable as the first EWK one. This oil change kit also doesn't have a manual hand pump option.


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


  • Makes noise while sucking oil

4. Qiilu Fluid Pump Extractor

The Qiilu oil extractor looks a lot like the one we mentioned above from DasMarine. It is an ideal tool for a quick and clean oil change, 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 is one of the options to consider.

This is easily one of the best electric oil extractors for a boat. It will facilitate the quickest and cleanest extraction for you. This oil change system is quite easy to use also.

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. This may take a little extra effort to complete. 

This oil changer is extremely versatile and easy to use. 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 that.

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. This one is also easy to transport if you need to use it on the go.


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


  • Doesn’t come with a fluid tank

5. YOMNEE Electric Transfer Pump

This is the most versatile pump we came across. It can be used in many areas like auto and marine engines, drinks transfer, summer cooling, garden cleaning, agricultural irrigation, industrial applications, DIY, and more. Due to its small size, you can also store it in any available space.

Not everyone is ecstatic about pumping oil manually with their hands. It takes 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.

The versatility of the Tomnee transfer pump is so great that it can drain fluid from any equipment, including your boat, shipbuilding, chemical and medical equipment, floor and carpet cleaning, water treatment equipment, etc.

In addition, the cable has an impressive 70cm length to ensure your comfort while operating.

Also, this powerful electrical boat oil extractor can suck a good amount of fluid and transfer into an outside container without consuming too much energy.

Once you insert it into your boat or car’s oil pan, it will powerfully drain out all the fluid within a few minutes.

Its multiple hoses make the extraction more convenient and easy. Another advantage of this unit is that it can be used for both small and large scale operations with efficiency, and it's easy to transport.

So, if you are after saving time and cost-effectiveness, this unit is probably the one to pick.


  • Easy to carry and store
  • Powerful electrical motor
  • Extremely versatile pumping
  • Fastest fluid transfer


  • Wires run a bit short

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 battery.

Important Features to Consider

When you invest in a boat oil extractor, you want a return on your investment. 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. Getting a smaller size unit means less weight and it's 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 lot of money in the long run. They also 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.

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