Yamaha Outboard Filters and Strainers FAQs
What is a Yamaha 10-micron fuel-water separating filter?
This filter helps separate water from fuel and also helps keep debris bulk oil out. It is recommended to change this filter every 50 hours. We also recommend carrying a spare fuel-water separating filter on board in case you get a tank of bad gas, and the filter is overwhelmed. Shop Yamaha fuel-water separating filters
What is Yamaha VST Filter? / What is a Yamaha VST filter?
The VST filter on a Yamaha outboard is a small screen located inside the Vapor Separator Tank (VST). Its purpose is to prevent debris from entering the fuel injectors and causing damage to the engine. The VST filter should be cleaned or replaced as part of your regular maintenance routine.
This filter is attached to the electric fuel pump in the VST and filters gas again just before it’s pressurized into the fuel injection rail(s). The VST is a prime spot in the fuel system where deposits and gum can form, particularly if fuel is untreated. Protect this filter by consistently treating every tank of fuel with Yamaha Ring Free Plus and regularly inspect and service the first two filters in the electric fuel pump in line. Refer to the specific engine’s service manual for the recommended service interval and the exact location of the filter. Shop Yamaha VST filters
What is the difference between a primary filter and an in-line filter?
This Yamaha fuel filter is typically on the front, side, or rear of the powerhead, and is usually made of plastic you can see through. It filters fuel coming into the outboard. This “primary” fuel filter also usually features a small water trap at the bottom of the cup. This is the first filter after the 10-micron filter, so if there’s water in here, it’s time to change your 10-micron. On Yamaha outboards, there may be a red ring visible inside this filter. Don’t ever remove it. If it’s floating, you’ve got water in this filter’s trap and it time for a change. Shop Yamaha primary on-engine filters
Some models have an in-line filter between the Yamaha primary fuel pump and the VST (vapor separator tank) and/or in the fuel line between fuel pump, the VST and the fuel rail, located along the top of the outboard. Refer to your service manual or contact your dealer for the exact location for your model. Shop Yamaha in-line filters
What are common Yamaha outboard engine fuel system issues?
One of the most common ways your Yamaha outboard motor will break down is a fuel system failure. Whether you’re experiencing an intermittent bog down, poor performance, or complete engine failure, your fuel system is a common culprit.
-
Ethanol gasoline: Only use premium low-ethanol gasoline for your Yamaha outboard motor. The reason is that ethanol attracts water, causing fuel to dilute through “phase separation.” Additionally, ethanol gasoline can also gunk up fuel lines and fuel system components due to additives used. To help prevent these issues, regularly use a high-quality fuel stabilizer.
-
Fuel lines: Check your fuel lines. If you discover any breaks or leaks, you should stop using the engine and make any necessary replacements. Also, take a look at any fuel hoses with an interior liner.
-
Fuel filters: The Yamaha fuel filter is designed to catch any debris and contaminants that have entered your fuel system. Regularly replace your fuel filters to keep fuel running freely.
-
Fuel pump: A malfunctioning Yamaha fuel pump can significantly reduce engine performance and, over time, severely damage other components. If your fuel pump is not working correctly, replace it and any hoses that may have been affected.
Why are there so many Yamaha outboard filters?
It’s no secret that Yamaha fuel filters are necessary for outboard engines to perform properly in the harsh marine environments they regularly encounter. But the question remains, why are there so many Yamaha outboard fuel filter replacement options?
The answer is simple yet complex. All dirt is not created equally – dirt appears in various forms and sizes. Some dirt particles are larger pieces, and some are minute dust particles. Some material you can easily see, other material can be microscopic biological growth and may still be growing.
Dirt takes different forms. It may be shaped like a ball or more like an arrow. The ball type usually gets caught easily, but the arrow type may penetrate the first and second filter and get stuck in the third. Once the arrow lays across the filtering medium, it partially closes the passage holes and makes them smaller, capturing even smaller debris. The clogging will then continue. If the initial filter really becomes restricted, the vacuum on the filter may suck the debris through it and on to the next filter, and so on.
Poor fuel quality, water, ethanol, lack of fuel rotation, and biological growth all add up to clogged filters. This is why it’s essential to change all Yamaha fuel filters on a regular basis based on factory guideline recommendations. Always be sure to refer to the specific engine’s service manual for more information on recommended service intervals and the location of filters.
Some Yamaha four-stroke outboard engines require several of the fuel filters below or screens to help prevent water and debris from getting inside the engine.
How do I change my Yamaha 2-stroke outboard engine oil?
If your two-stroke Yamaha outboard has oil injection with a remote oil tank inside the boat, you will begin your service by accessing this tank. These remote tanks are not always situated in the easiest-to-reach places, so you may have to consider removing a livewell tub, cooler, or access panel to get to the tank. Loosen the tank from its bracket and locate the oil supply hose that comes from the pump on the tank and heads toward the engine. You should notice a small, white, inline filter that strains the two-stroke oil line in route to the engine. This small filter is often overlooked, but without a steady supply of Yamalube two-stroke oil, your engine will quickly go into reduction mode, or worse. Cut the small zip ties that secure the oil line to the strainer and replace the strainer quickly before you drain oil all over the bilge. This process is a little messy, so a few petroleum sorbent pads can help avoid a mess. Having some good quality nitrile gloves on board the boat or around for your service is also a great idea.
With the tank loosened from its bracket, it is a great time to use a small service flashlight to illuminate the bottom corners of the tank. The clear plastic will allow you to spot any debris or water deposits accumulated inside the tank. If found, you will need to remove the tank, drain, and clean. Debris is most often introduced from fill caps being left open, damaged fill cap o-rings, or dirty containers used to purchase bulk oil.
When complete, reinstall the tank into the bracket and remove the cowling from your engine. Use the manual transfer switch on the side of the engine to verify oil is flowing through your new filter and the system is primed. Your Yamaha 2-stroke oil maintenance is now complete. You are ready to begin your engine service.
Should I only use premium low ethanol gasoline for my Yamaha outboard?
Yamaha recommends the use of gasoline with a minimum octane rating of 87 (R+M)/2 for their outboard engines. While using premium gasoline with a higher octane rating may offer some benefits such as improved performance, it is not a requirement for Yamaha outboard engines.
However, Yamaha does recommend using gasoline that contains no more than 10% ethanol (E10) and avoiding gasoline blends that contain higher amounts of ethanol as this can cause damage to the engine. It is also important to follow the fuel requirements and recommendations outlined in the owner's and service manual for your specific Yamaha outboard engine.
What are Yamaha strainers for outboard motors used for?
Yamaha strainers for outboard motors are used to filter out debris, dirt, and other contaminants from the fuel or oil system. They are typically installed in the fuel or oil lines to prevent particles from reaching the engine and causing potential damage. Strainers help to ensure that only clean fuel or oil flows into the engine, improving engine performance and protecting the internal components from harmful contaminants. Regular maintenance, such as cleaning or replacement of strainers, is important to maintain optimal performance of Yamaha outboard motors.
Do Yamaha outboard engines have air filters?
Yes, most Yamaha outboard engines have an air filter. The air filter is typically located near the carburetor or fuel injection system.
How to change Yamaha 150 VMAX outboard injector filters?

-
Turn on the engine and check for leaks.
What are the most common sources of fuel system contamination?
Contamination in the fuel system can cause serious damage to your Yamaha outboard engine. Common sources of fuel system contamination can include water, dirt, and debris in the fuel tank or fuel lines. Regular maintenance, such as changing the fuel filter, can help prevent contamination from causing problems.
How often do you change a fuel filter on a Yamaha?
It is recommended to change the fuel filter on your Yamaha outboard every 100 hours of operation or at least once a year, whichever comes first. However, if you frequently operate your motor in dirty or contaminated water, you may need to change the fuel filter more often.
What is the difference between oil filter and oil strainer?
The oil filter on a Yamaha outboard engine is designed to remove contaminants from the engine oil, while the oil strainer is a small screen that prevents debris from the oil supply hose entering the oil pump. The oil filter is typically replaced during routine maintenance, while the oil strainer is cleaned and inspected.
Can I reuse Yamaha outboard oil filters after changing my oil?
No, it is not recommended to reuse oil filters. It's best to replace them with a new one each time you change your oil to ensure optimal filtration and protection for your Yamaha outboard motor.
What is a Yamaha 115 fuel water separator?
A Yamaha 115 fuel water separator is a filter designed to separate water and contaminants from the fuel system of a Yamaha 115 outboard motor. It helps prevent water and debris from entering the engine, which can cause damage and reduce performance.
Why is a Yamaha 115 fuel water separator important?
A Yamaha F115 fuel water separator is important because it helps protect the engine from damage caused by water and contaminants in the fuel. It helps ensure clean fuel reaches the engine, which can improve performance, fuel efficiency, and extend the life of the engine.
