Yamalube Fuel Additives and Fogging Oils FAQs
How do I fog my Yamaha outboard engine?
Before fogging your Yamaha outboard engine, you’ll need the following:
So, what is fogging oil or fogging fluid anyway? Yamalube fogging oil is a wax-based oil that coats the engine and prevents corrosion. As you work through this process, you will soon understand why this process is called fogging the engine as there will be plenty of white smoke.
Since you will not be in the water while performing this task, you will need to use a motor flusher to empty salt water to keep the engine cool while you complete the fogging process. Follow the Flush Your Outboard with the Engine Running procedures detailed above.
If applicable, remove your engine’s air cleaner to get to the carburetors or cylinder air intakes.
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.
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 ultimate 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 to move the cylinders allowing you to coat the entire cylinder wall. Rather than turning the flywheel to move the cylinders, 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 for good measure. Replace old spark plugs with new spark plugs so that you are ready to go in the spring.
How do you fog a Yamaha outboard motor? Quick Guide
Here are the steps for Fogging a Yamaha outboard motor for shipping::involves using a specialized fogging spray to protect the engine during storage and shipping. :
-
Start the engine and let it idle until it reaches normal operating temperature.
-
Turn off the fuel supply or disconnect the fuel line to prevent the engine from running out of fuel while fogging.
-

-
Slowly turn the flywheel several times to distribute the fogging oil throughout the cylinders.
-
Replace the spark plugs and tighten them to the manufacturer's recommended torque.
-
Spray a light coat of fogging oil over the engine's exterior surfaces, such as the carburetor, throttle linkage, and other metal parts.
-
Finally, turn off the engine and store it in a dry, cool place away from direct sunlight.
Fogging your Yamaha outboard motor is an important step in maintaining its performance and prolonging its lifespan.
Before stabilizing the fuel system of your Yamaha outboard engine, you’ll need the following::
Because it is so common, many of us use ethanol-enriched gasoline much of the time. We recommend using a fuel stabilizer all of the time when running ethanol-enriched gasoline. Read our Ethanol Gasoline In Outboard Engines article to learn why. Additionally, it is vital to use a fuel stabilizer like Yamaha Fuel Stabilizer and Conditioner Plus when your boat will be sitting unused for any more than two or three months.
Add the amount of fuel stabilizer directed on the product’s packing to your fuel—for instance, 1 ounce of Yamaha Fuel Stabilizer and Conditioner Plus for every gallon of gasoline, assuming the engine will be stored for more than 2 months. If you are storing the engine for 2 months or less, the suggested ratio from Yamaha is 1 ounce of stabilizer for every 3 gallons of gasoline.
Run the engine with stabilized fuel for 10-15 minutes to thoroughly circulate the stabilized fuel throughout your fuel system. If your boat is out of the water, follow the Flush Your Outboard with the Engine Running procedures detailed above.
Why is my Yamaha outboard fuel system important?
The fuel system is composed of the fuel pump, fuel filter, check valves, fuel hoses, fuel pump diaphragm, and injectors. Listen for the operation sound. If you can’t hear the system attempting to work, check for continuity between the fuse holder, fuse, fuel pump relay, and wiring harness. Repair or replace the defective part(s) if there is no continuity. If there is continuity, replace the electrical fuel pump. If you hear the operation sound, check each part of the fuel system individually.
First, inspect the Yamaha fuel filters and look for clogs, cracks, kinks, or leaks in the hoses. Replace any parts with damage. Next, check the diaphragm for cracks or other signs of damage. Then, check the vapor separator needle valve for bends or signs of wear. The next step is to check the injectors for clogs and resistance. Then, check for poor connections.
Finally, note if there is any water in the fuel. Ethanol gasoline attracts water, which negatively impacts the combustibility of the fuel. This is especially likely if you haven’t used fuel additives or stabilizers. Water in the fuel may also cause a bad or failing fuel pump. If you find water in your fuel, you may want to check that the pump is in good condition.
You can perform a Yamaha outboard fuel pump test by removing the spark plug wire boot from the spark plug and then removing the spark plug with a plug socket and wrench. Attach a compression gauge into the spark plug socket. If you have an electric motor, you may need a second person to crank your engine over while you twist your throttle position open. Otherwise, you can push the throttle open with one hand and pull the rope start.
Why is a proper Yamaha outboard season breakout important?
At the start of a boating season, we highly recommend going through the proper Yamaha outboard season breakout steps. We’ve all experienced that there are two different kinds of people at the launch ramp: those who are prepared, and those who are not. You don’t want to be the person to get your family and friends excited for a long-awaited trip on the water, only to disappoint because your engine won’t startup. Doing some simple maintenance on your Yamaha outboard before breaking out your boat will save you from a lot of embarrassment and wasted time.
How do I perform a Yamaha outboard season breakout?
1 – Add Yamaha Ring Free to your fuel tank and top off the gas. There are differing thoughts on filling the fuel tank before storage. Whatever your approach, good fuel treatment at the start of the season is important. PartsVu recommends Ring Free and Yamaha Fuel Stabilizer and Conditioner with every fuel up, especially if ethanol fuel is being used.
2 – Check the fuel system connections for leaks and the fuel hoses for softness or brittleness. Replace if needed.
3 – Check the grounding cables on the engine mounting bracket for breakage or corrosion. Clean them if necessary.
4 – Charge your batteries, and reconnect the battery cables if you disconnected them before storage. A trickle charge is always the best way to preserve the life of your battery during storage. Yamaha Battery Terminal Cleaner and Protector is extremely helpful to remove corrosive build-up on battery terminal posts to help increase power output and extend battery life.
5 – Check your propeller. Remove the propeller, use Yamaha Marine Grease and check that the lower unit seal is not compromised.
6 – Inspect for any leaks out of the lower unit. Yamaha Gear Lube Kits help you to properly maintain your lower unit.
7 – Steering – move the steering wheel, checking for free movement through the full range.
-
Mechanical Cables – grease the ends of the cable where it connects to the helm and to the engine.
-
Hydraulic – check for any hydraulic oil leaks, examine the hose, especially hoses by the engine and cylinders. Add marine hydraulic steering fluid as needed.
-
Power-Assisted Systems – check for any leaks, examine hoses, check/fill reservoir.
8 – If your outboard is equipped with a power trim and tilt system, check that its operation is functioning as it should. Look for any fluid seepage around the piston seals and reseal/replace as needed.
9 – Test run the motor before launching the boat, burning off any fogging oils or other storage elements introduced into the engine. This provides an opportunity for you to check all of the gauges, electronics/navigation systems, examine for leaks, and verify overall operating functionality before your first trip. (When running your engine out of water, the team at PartsVu recommends using engine flushing earmuffs for the lower unit).
