That’s because our waterways are usually more wet and saltier than the ground. This means that your boat may corrode and rust very quickly.

Frequently Asked Questions (FAQ)

What is the best marine grease?

The key to a good marine grease is the ability to get a long working time while still being able to set up quickly.

A typical application for marine grease is to be used to lubricate and preserve rubber parts like the belts on a boat or the seals on a live well pump.

If you look around you will likely come across verner bearings grease. This is not really a marine grease, it's the wrong type of grease. It is great for your car though. If you find it, it has a great long working time and a good price.

Some of the best marine grease on the market today is molybdenum-based and polymer-based greases. They can be used in both freshwater and seawater and can perform exceptionally well in the extreme demands of marine applications. They have been formulated to have a no-clean up characteristic which makes it extremely easy to maintain the greased surfaces.

What is the best grease for tractors?

The best grease for tractors will vary depending on the environment that it is being used in and the specific requirements of the tractor. These greases are required to have a very high viscosity index as well as an ability to work in extreme cold and heat.

When you purchase a tractor, it is a great idea to ask what grease was used during assembly and then follow that recommendation for maintenance.

Normally, the grease is never really changed once it has been initially applied to the agricultural machinery. Most owners of tractors never really pay too much attention to when it comes to lubricating.

If you do not already have any idea what type of grease was used during assembly, then purchase a regular grade grease that will work well in a variety of conditions, such as the STP Gear Grease.

Is Marine Grease good for wheel bearings?

When you are replacing the wheel bearings in your vehicle, it is time to change them to the ones with marine grease if you are going to be driving your vehicle in a marine-based environment. You can also buy marine grease without changing the wheel bearings.

Marine grease is good for a wide variety of applications. It is used to lubricate engines, to protect boat hulls, and to keep out water. The packaging should show which environment the grease is good for.

What grease should I use on my boat trailer?

Assuming you have already made sure that the lug nuts on your trailer are in good condition and that you have checked them (and not just your spare tire) if your boat is equipped with trailer tires, next you should inspect the grease fittings.

If you are on the water, you should keep your boat trailer greased at all times to protect your wheel bearings and your tow vehicle’s driveshaft.

The grease fittings should look clean and smooth. If they are corroded or if the threads are rusted, they will need to be replaced. What kind of grease should you use? Well, marine grade grease is the only type of grease that should ever be used on marine or boat equipment. This is because it is designed to protect against corrosion and inhibit the growth of microorganisms.
