Suzuki Outboard Exhaust & Exhaust Components FAQ
How do I fog my Suzuki outboard engine?
Fogging oil is a wax-based oil that coats the engine, removes carbon deposits, and prevents corrosion. Fogging your Suzuki outboard is a smart move for winterization, as water deposits and other harmful corrosives (including leftover fuel) can eat away at the metals in the outboard engine. (Read “How To Winterize a 4-Stroke Suzuki Outboard Motor” about winterization)
As you work through this process, you’ll understand why this process is called fogging, as the engine will produce plenty of white smoke to indicate that the oil has worked its way through your engine.
Because you will not be in the water while performing this task, you will need to use a motor flusher to keep the engine cooled at a safe operating temperature while you complete the fogging process. Follow the Flush Your Outboard with the Engine Running procedures detailed above.
Before fogging your Suzuki outboard engine, you’ll need the following:
- Fogging oil
- Crescent wrench
- Replacement spark plugs
- Motor flusher
- Garden hose
- Water supply
Begin by either removing your engine’s air cleaner to gain access to the carburetors or cylinder air intakes.
Once you have access to the carburetors or cylinder air intakes, disconnect the fuel line. The purpose of this is that the fogging oil forms a barrier against any new gas, while also removing the old fuel.
Rev the engine to a bit above idle, and with the engine running, spray the fogging oil into the carburetor(s) or air intake of each cylinder. You may need an assistant to spray the oil or rev the engine depending on how your Suzuki outboard is mounted.
Continuously spray fogging oil into your engine’s carburetors or cylinder air intake until the engine stalls. Be sure to spray a coating of fogging oil into each cylinder or carburetor. Don’t spray too much oil at once and kill the engine immediately, but after a continuous spray, the engine will eventually stall. This is precisely what you want, and the stalling indicates that the engine is thoroughly covered with fogging oil.
Next, use your crescent wrench to remove the spark plugs and spray fogging oil into each cylinder. Turn the flywheel with a crescent wrench to move the cylinders allowing you to coat each cylinder wall entirely. Alternatively, you can also simply start the engine for just a few seconds to allow the fogging oil to coat the cylinder walls. Repeat this process a couple of times to be sure that you’ve adequately coated each cylinder.
Last, replace old spark plugs with new Suzuki spark plugs so that you are ready to go in the spring.
What are the symptoms of a bad fuel pump on my Suzuki outboard motor?
When you try to start your engine, you should be able to hear the sound of the Suzuki fuel pump engaging. If that familiar sound can’t be heard, there’s a chance it could be due to issues with the battery. Check the battery first, and depending on other symptoms you may be experiencing, it could be a good idea to troubleshoot other systems with one of our handy guides. Still, if you’re missing that motorized sound, that’s a strong sign that the fuel pump may be having issues.
Another common symptom of a bad fuel pump is sputtering or misfiring. If you’re experiencing a bumpy ride (or possibly losing speed altogether), it could also be a sign of a clogged fuel filter that won’t allow a consistent flow. You’ll want to check the entire Suzuki fuel system to ensure that any clogs and blockages in the system are addressed. We outline what parts of the fuel system you need to check in our Suzuki and Suzuki troubleshooting guides.
What are common Suzuki outboard engine fuel system issues?
One of the most common ways your Suzuki 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 Suzuki 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 and other Suzuki fuel additives (such as Suzuki ECSTAR Fuel Conditioner & Water Remover).
- 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 Suzuki 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 Suzuki 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.
How do I service my Suzuki 4-stroke outboard fuel system?
Depending on your application and style of boat, your Suzuki fuel system may include a fuel-water separating filter. If you have not seen one, follow the routing of your fuel hose from the engine rigging tube backward through the boat. These vary in shape and manufacturer, so be sure to order the identical replacement size for the best fit. Verado owners may not have an inline filter as the engine has a water separator under the cowling.
Use a filter wrench to loosen the existing filter element and use caution when removing it as it will be filled with gasoline. A clear plastic or glass container is helpful to dump the filter and examine the contents. A small amount of debris is common, as is a small amount of water after the fuel has had a moment to settle. More significant amounts of water would warrant further investigation.
If your filter’s mounting location allows it, pre-fill the replacement filter with some gasoline to make re-priming the fuel system easier. It is also advisable to use a small amount of grease or engine oil to lubricate the o-ring before installation. Spin on and hand tighten only about a half turn to snug.
Move back to the engine and locate the filter element(s) on the engine. The scope of this service will only include the low-pressure fuel filter and fuel water separator if applicable by model. Suzuki recommends that owners do not service their high-pressure fuel filters. Depending on your engine model, the water separator filter (or castle filter) may be removed by using a wrench, standard tools, and a little caution. Unplug the water-in-fuel sensor if applicable and spin the cap off of the housing. Replace the filter element with a fresh one, lube the o-ring with grease or oil, and carefully reinstall the cap.
For most other models, the low-pressure fuel filter is inline where the fuel supply line passes down the side of the cowling. On applicable models, locate the Schrader valve on the fuel system. Cover the valve with a rag or towel and depress the valve stem to vent the pressure from the system before service. With the pressure vented, remove the inline filter and replace it with a new one paying particular attention to locate the clamps or zip ties securing the hoses to the filter.
Locate your engine’s primer bulb if applicable and use the primer to pump up the fuel system. You should feel and hear gasoline entering and filling the filter cup. Check for leaks and prime until the bulb becomes firm.
If you are not already regularly running Suzuki ECSTAR Fuel Injector Cleaner (for fuel injected engines) or Suzuki ECSTAR Fuel Conditioner & Water Remover through your Suzuki fuel system, the 100-hour service interval is an excellent time for a “shock treatment.”
Suzuki ECSTAR Fuel Injector Cleaner is a fuel system cleaner and top-lube that will help to clean deposits from the tank, lines, carburetors, injectors, and pumps. It breaks up fuel system varnish and will help to prevent gumming.
Suzuki ECSTAR Fuel Conditioner & Water Remover is a fuel system conditioner that also helps to remove carbon deposits. It prevents phase separation that draws water into the engine, while also removing any moisture in the fuel system to prevent corrosion.
