Perhaps the game of soccer isn’t meant to be perfect in all aspects—as it was first played there were a lot of inconsistencies and it seems as though there will always be some elements present that make the game play different every time. Maybe we should leave the soccer ball as it is and focus on something different . . . super human cleats, perhaps?

Among the trailer features that should be on your regular checklist are the wheel bearings – more specifically, the bearing grease. These bearings are located inside the hubs on the trailer axle and allow the wheels to spin freely as you travel down the road. While traveling, the spinning force generates friction, and the friction generates heat. To keep the bearings from overheating, they need to be lubricated, which is done by filling the inner part of the hubs – the part containing the bearings – with grease.
The pig’s bladder just wasn’t doing the trick for people, so in 1855 Charles Goodyear made the first vulcanized rubber soccer ball— this was a huge step as it started to standardize the size and shape of a soccer ball. Pig’s bladders came in all different shapes and sizes and they were near IMPOSSIBLE to control! You never knew where they would end up each time you kicked it. The next version of a soccer ball came in 1862, from H. J. Lindon. He created an inflatable rubber bladder, which was much lighter than Goodyear’s rubber ball, and would retain its shape a bit better.

Happy summer everyone; I hope you’re enjoying beautiful weather and being entertained by the awesomeness that is the World Cup. I’m pretty confident that at least 99% of us played soccer when we were kids. I know I did and still enjoy a pick-up game now and then. Did you ever wonder why the soccer ball has the hexagonal shapes, and why the “traditional” ball is black and white? I didn’t (I preferred some awesome colored soccer balls, to be honest) but I decided to have a look into the evolution of a soccer ball to see if there is rhyme and/or reason behind all the details (spoiler alert: there’s a lot of reason… not sure if there will be rhyming).
Once the 1960s came, soccer balls were made completely from synthetic materials. Architect R. Buckminster Fuller created the iconic soccer ball we all know and love using 20 hexagonal and 12 pentagonal pieces stitched together to form a sphere. This is when the black pentagons were iconically added. The reason for the black pieces was to allow players to learn how to curve a soccer ball and track its path. It was called the “Buckeyball”, and this is the ball that is still being manufactured today.
There was another problem with these balls. They tended to become waterlogged in rainy regions (like the UK). In 1940 the soccer ball was given a strong layer in between the bladder and the outer covering to increase the durability of the ball, and synthetic, non-porous materials were used for the outer covering to make the ball waterproof, and a valve was added on the ball to replace the slit.

2. Check the grease level by pressing on the edge of the spring-loaded piston. If you can move or rock the piston, the hub has enough grease. Don’t add anymore. If the piston doesn’t move, you need to add more grease.

Not every trailer is equipped with spring-loaded bearing protectors. Your trailer might have sealed grease hubs, oil bath hubs or some other variety. Some are designed to be essentially maintenance free throughout the season, but you should still always check to make sure you have the appropriate amount of lubricant, there are no leaks and that your hubs are not excessively hot after towing.
This year in the World Cup, there is a new feature to the soccer ball – goal-line technology. That’s right! The referees now wear a watch-like device which speaks to a sensor in the soccer ball and will tell the referee if the ball has crossed the goal line or not. No need for instant replay here! There are some great science resources out there about the technology and science behind the ball. A fascinating article from Compound Chemistry looks at the chemistry of the world cup ball – dubbed the “brazuca” – which is mostly made of polymers. MIT explains in this article how the ball swerves, while NASA has been involved in testing the ball using a wind tunnel and water channel:
3. Mount a hand-pump grease gun to the grease fitting, often called a grease zerk, in the center of the piston. Pump in grease until you see the piston start to move out then continue adding grease until the piston rocks approximately 1/8 inch when you press on the edge.
Above all, always follow the maintenance instructions and service schedule outlined by the manufacturer. A trailer shop or a Mercury Authorized Dealer can offer advice or service if you’re not comfortable handling trailer maintenance yourself.
Back in medieval times there would be town-wide soccer games. What did they use, a Nike soccer ball? Perhaps an Adidas ball? Nope. They used animal skulls! Or a pig’s bladder. Can you imagine using a skull? I am sure they didn’t wear cleats (studs) or have shin pads so that must have been either a very painful game or slow-moving game. A pig’s bladder sounds like it would be much better than a skull but much, much less durable. I’m not an expert on organs, but I feel like a bladder would not be very light or have much “spring” or “bounce” to it.
Keeping the bearings lubed and topped off with fresh grease can help ensure you get to and from the ramp safely and without headaches.

This process is simple, as shown in the video below by our friends at Wired2Fish. Just be sure to use a marine-appropriate grease, such as Mercury 2-4-C Marine Grease or Mercury High Performance Extreme Grease. Each is a high-quality grease that won’t break down in the presence of water.

To prevent this issue, many boat trailers are equipped with bearing protectors such as the Bearing Buddy®, one of the most popular brands on the market. Essentially a cylinder that is installed in the outer part of the hub, a Bearing Buddy has an internal spring that keeps constant pressure on the grease in the hub. The pressure helps prevent water from being pulled in past the seal.
In the 1900’s soccer was becoming so popular that there was demand to make the balls stronger and more durable to withstand the toughest of play. Until this time, soccer balls were made from leather-covered inner tubes or rubber bladders. Now they were hand-stiching tanned leather panels and leaving a slit so that a synthetic bladder could be inserted into it. These were considered works of art, but unfortunately still had inconsistencies and teams were lucky if a ball lasted through one game. These balls would cause controversy as it was thought that having the skill to pick the right ball was just as important as one’s soccer playing skills. This was the case in 1930 for the first World Cup – it is thought that the outcome of the game between Argentina and Uruguay was largely due to the quality of soccer ball each team was accustomed to.
A decade later, the English Football Association finally gave weight and size regulations for soccer balls to bring more consistency to the game. They stated that the ball should be “spherical with circumference of 27 to 28 inches”, weight 13-15oz. Law of Football required it to also have an “outer casing of leather or other approved materials.” This then lead to mass production of soccer balls—higher quality balls had leather hide from cow rump, lesser quality from had leather from the cow’s shoulder. These were hand-stitched so there were still small variations and minor inconsistencies in the ball. Another fun fact- the game of basketball was invented with this version of the soccer ball!

4. Though not required, you can also jack up the trailer so you can spin the tire freely to help distribute the grease before towing.
Just imagine all the different ways one can still improve on the soccer ball? I bet someone can characterize all the different materials used to create the ball and determine the perfect specifications for a ball that will be more sensitive to the angle at which it is kicked to allow for more precise “curving” by players. Maybe a soccer ball with a material that will compensate for any moisture accumulation and automatically adjust weight distribution (ok, maybe that’s a bit of a stretch).
Lubricating your bearings is important on any trailer, yet on a boat trailer, there’s the added challenge of regularly submerging the hubs and wheels in water when launching the boat. When the trailer is submerged, the hot hubs and bearings cool immediately. This creates a vacuum that could draw water in through the bearing seals.
Another big benefit of bearing protectors is that maintenance is minimal. Typically, you don’t need to clean out and repack the grease for several years, though you’ll want to check the manufacturer’s instructions to make sure you repack them at the appropriate frequency. You do, however, need to check the grease level and top it off if needed.
Most importantly, make caring for your trailer a priority because it’s vital for keeping you and your boat rolling trip after trip, season after season.
Unless you keep your boat in a marina, a good day on the water starts with trailering to the ramp. That’s why it’s important you stay on top of trailer maintenance.
