Can you use ethanol in a boat?
Let’s assume the adventure you have been planning does not include the episode where your boat is bobbing dead in the water while you troubleshoot a tank full of crappy gas. Here’s how to avoid that scenario. Ethanol remains the leading culprit of fuel issues in gasoline-powered marine engines — ethanol is corrosive, it’s a solvent, and it absorbs moisture. In a boat it’s nothing but trouble. The obvious action is to not fuel your boat with an ethanol-blend gas. When that’s not an option, you need an ethanol defense strategy, like these tips we’ve gleaned from Yamaha Marine.
Top 10 Ethanol Fuel Treatment for Boat Reviews
After reading the Stabil ethanol treatment review, I was determined to get this product. It’s not a wrong move as my boat runs more smoothly after using it. I was thrilled to find that it can deliver a lot of benefits. Hindering water-related issues in injectors is one of them.
Is Ethanol Gas Bad For Boats
Marine engines are designed to handle ethanol gas or E-10 bears 10% ethanol. It’s recognized as a superior marine fuel because it can maintain low levels of water and keep the system dry. However, it’s necessary to treat it if not used within a few weeks. It’s a must if an engine is set aside for winterization or long-term storage.
Does Fuel Stabilizer Prevent Ethanol Damage
Yes, it does. As mentioned, damages on the boat engine are from phase separation. But fuel stabilizers can counter them by prolonging their life span and functions. It also protects against sludge, corrosion, rust, and other contaminants that impede engine performance.
How Much Additive Do I Need To Remove Ethanol From Gas

What is fuel oxy?
The Fuel Ox Complete Fuel Treatment and Combustion Catalyst is a high quality boat engine fuel additive designed to improve the health of an engine. This product cuts regenerations and emissions. It provides an earlier ignition and through burn of fuel.
What is viscosity of boat fuel additive?
The viscosity of boat engine fuel additive is the measurement of how easily additive pours at specific temperature. The lower the viscosity number is, the thinner the additive. This will result in easier pouring than a boat engine fuel additive which has a high viscosity number; however these additives are more effective at maintaining strength of film and pressure at higher temperatures.
What are boat additives?
Boat engine additives are compatible with different engine types. Some will be suited to certain types of engines. Other additives will be compatible specifically with 2-Stroke while others will be universal.
Is boat fuel additive good?
Choosing high quality boat engine fuel additive is a wise investment for a boat owner. A relatively low priced-item, engine additive could be mistaken as not being important. In terms of maintaining the good condition of the engine, it is actually a very important item. The wear and tear of a functioning boat engine and the metals rubbing together will inevitable cause damage over time. Engine additive prevents this damage from happening.
How to limit problems with a changeover to E10?
To limit problems with a changeover to E10: Check for the presence of water in the fuel tank. Inspect the water-separating fuel filter on larger engines. If water is found, pump the tank dry from the fuel line or siphon the tank dry. Examine the fuel in a clear container. If the fuel is not clear or has a sour odor, the tank should be cleaned.
How much water does an E10 hold?
E10 can hold approximately 0.5% water at 60°F (.64 ounces in a gallon, or 12 ounces of water in a 20-gallon gas tank), but can only hold about 0.35% water at 20°F (.45 ounces in a gallon). If possible, store your boat for the winter with a full fuel tank. Add a fuel stabilizer to the fuel at the recommended dosage.
How to prevent fuel from going bad?
To prevent fuel from going bad, most manufacturers recommend high-quality fuel additives to prevent sediment, gum and varnish buildup that forms when fuel goes bad, control moisture, help prevent phase separation and prevent fuel system corrosion. MYTH: Ethanol-blended fuels are bad and should be avoided.
Can fuel additives cure ethanol?
Ethanol myths. MYTH: Fuel additives can cure or prevent all issues from ethanol-blended fuel. TRUTH: There is no practical additive that can prevent phase separation from occurring. The only practical solution is to keep water from accumulating in the tank in the first place.
What happens when E10 gas comes into contact with water?
When E10 gasoline comes into contact with water, ethanol will allow fuel to absorb some or all of that water. This is actually somewhat beneficial, but fuel can reach a saturation point and water can phase separate to form a distinct layer in the bottom of the tank. The upper “gasoline” layer will be depleted of ethanol and have a reduced octane level. The lower “phase separation” layer will be a corrosive mix of water and ethanol. No chemical agent or fuel additive can be added to E10 gasoline, in a reasonable quantity, that will fully prevent phase separation or recombine a phase-separated layer.
When to use E10?
The most likely time for fuel problems occurs when you first begin using ethanol-blended fuel. When E10 is added to a fuel system that has been using non-ethanol gasoline, ethanol, as a new solvent, will tend to dissolve and loosen deposits that are present in the tank and fuel system. Phase separation may occur, resulting in an approximately 50/50 ethanol and water layer at the bottom of the fuel tank. To limit problems with a changeover to E10:
What to do if you change to E10?
If you change over to E10 from non-ethanol gas, you should check for water in the water separating fuel filter. Carry spare filter elements, as ethanol is a solvent that loosens gunk in the fuel system.
Why is it important to use the correct grade of fuel?
Using the correct grade of fuel helps to ensure optimum performance, economy and reliability from your engine. It is important to follow the recommendations for your model engine as incorrect fuel can damage your engine or affect performance.
What is the ratio of autoblend oil to fuel?
Autoblend models have an oil reservoir mounted inside the boat that automatically blends oil with the fuel at a constant ratio of 50:1. 2-stroke oil is added to the reservoir and does not need to be mixed with the fuel (unless required for running-in)
Does fuel reduce engine life?
IMPORTANT: Using fuel that is below the minimum recommended octane may reduce engine life. Fuel recommendations are based on engines being set up and tuned to manufacturer's specifications. This includes using the correct propeller to allow engine to achieve recommended maximum RPM under typical load and conditions.
