Fuel - Lubes - Oils - Corrosion Protection FAQ

What are rust inhibitors used for on boats?

Rust inhibitors are chemicals that are applied to metal surfaces to prevent the formation of rust. They work by forming a barrier on the metal surface that prevents moisture from coming into contact with the metal. This can help to extend the life of the metal and protect it from corrosion.

On boats, rust inhibitors are often applied to metal parts and surfaces that are exposed to the elements, such as hulls, propellers, and engines. They can be applied as a coating or added to paint or other protective finishes. Rust inhibitors can help to protect boats from corrosion caused by saltwater, which can be particularly damaging to metal surfaces. They can also help to prevent rust from forming on metal components that are submerged in water, such as anchors and mooring lines.

In addition to protecting metal surfaces from rust, rust inhibitors can also help to improve the appearance of boats by preventing unsightly rust stains from forming. They can be applied to both new and old boats to help keep them looking their best.

What should I know about marine hydraulic fluid?

Marine hydraulic fluid is a type of lubricant that is specifically designed for use in marine hydraulic systems. Marine hydraulic systems are used in a variety of applications on boats, such as steering systems, anchor winches, and thrusters. These systems rely on the use of hydraulic fluid to transmit power and provide the necessary lubrication for the system's components.

Marine hydraulic fluid is typically made from a blend of mineral oils and other additives that are formulated to meet the specific needs of marine hydraulic systems. It is designed to provide good lubrication, corrosion protection, and stability in the presence of water. It is also resistant to foaming and air entrainment, which can cause problems in marine hydraulic systems.

The performance and durability of marine hydraulic fluid is important because it can have a significant impact on the performance and reliability of the hydraulic system. Using the wrong type of hydraulic fluid or using hydraulic fluid that has become contaminated or degraded can result in poor performance, reduced efficiency, and premature failure of the system.

What's the difference between WD40 vs Liquid Wrench? Boeshield T-9 vs wd-40?

Looking for the best marine lubricant spray or marine corrosion spray? WD-40, Liquid Wrench, and Boeshield T-9 are all lubricants that are designed to help loosen stuck or rusted parts and reduce friction. However, there are some differences between the two products.

One difference is the type of lubricant that is used. WD-40 is a water-displacing lubricant that contains a blend of petroleum and other chemicals. It is designed to penetrate rust and loosen stuck parts by breaking down the bonds that hold them in place. It is often used on outdoor equipment and machinery, as well as on household items such as locks and hinges.

Liquid Wrench and Boeshield T–9, on the other hand, are penetrating lubricants that are made from a blend of solvents and lubricants. It is designed to penetrate rust and loosen stuck parts by dissolving the rust and reducing friction. It is often used on automotive parts and machinery, as well as on household items such as locks and hinges.

Another difference between these two products is their intended use. WD-40 is primarily used as a lubricant, while Liquid Wrench and Boeshield T-9 are also designed to be penetrating oil. This means that Liquid Wrench/Boeshield T-9 is more effective at penetrating rust and loosening stuck parts, while WD-40 is better at preventing rust and reducing friction on moving parts.

Can I use automotive engine oil in my outboard engine? 

While many boat owners wonder about this, the short answer is that outboard motors are vastly different from your automotive engine, so you’ll want to avoid using regular automotive engine oils. Use the appropriate 2-stroke motor oil or 4-stroke outboard motor oil, which are specifically formulated for the rigors of the marine environment.

What are common outboard engine fuel system issues?

One of the most common ways your 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.

1. Ethanol gasoline: Only use premium low-ethanol gasoline for your 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.
2. 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.
3. Fuel filters: The 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.
4. Fuel pump: A malfunctioning 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.

What's the difference between marine grease vs regular grease?

Marine grease is a type of lubricating grease that is specifically designed for use in marine environments. It is formulated to withstand the harsh conditions found in marine environments, such as saltwater, high humidity, and extreme temperatures. Marine grease typically contains special additives that help it to resist water washout and protect against corrosion, making it a suitable water resistant grease for use in applications where regular grease might break down or become ineffective.

Regular grease is a general-purpose lubricating grease that is not specifically formulated for use in marine environments. It may not contain the same additives as marine grease and may not be as resistant to water washout or corrosion. Regular grease may be suitable for use in certain applications on a boat, but it is important to consider the specific requirements of the application and choose a grease that is appropriate for the environment in which it will be used.

In general, it is recommended to use water proof grease in marine environments, as it is specifically designed to withstand the harsh conditions found in these environments. However, it is always important to follow the manufacturer's recommendations and use the appropriate grease for the specific application.

What absorbs motor oil?

There are several materials that can be used to absorb motor oil, including:

1. Oil absorbent pads, absorbent mats for oil, and rolls: Oil absorbant pads are made from materials like polypropylene or cellulose, which are highly absorbent and can quickly soak up oil spills.
2. Clay-based absorbents: These are made from bentonite clay, which is highly absorbent and can effectively soak up oil spills.
3. Oil-only absorbents: These are made from materials that are specifically designed to absorb oil and other petroleum-based substances, but not water. They are often used in marine environments to prevent oil spills from contaminating the water.
4. Boom barriers: These are floating barriers that are used to contain and absorb oil spills in bodies of water. They are made from materials like polypropylene or polyurethane, which are highly absorbent and can effectively soak up oil.
5. Sorbent socks: These are long, tube-shaped absorbents that can be placed around oil spills to contain and absorb them. They are made from materials like polypropylene or cellulose, which are highly absorbent and can quickly soak up oil.

It's important to use the right type of absorbent material for the specific type of spill you are dealing with. For example, oil only absorbent pads may not be effective for certain types of spills that other sorbents are designed for.
