As the boating season comes to an end, many boaters are left with the decision of what to do with their boat’s gas tank for winter storage. While some may argue that it is necessary to fill the gas tank, others may say that it is not. So, which is the right answer? Let’s take a closer look.
Firstly, there are a few reasons why someone may want to fill their boat’s gas tank before storing it for the winter. One reason is to prevent moisture buildup in the tank. When a gas tank is empty, it creates a space for air to enter, which can lead to condensation and the buildup of moisture. This moisture can then lead to rust, corrosion, and other damage to the gas tank and fuel system.
Another reason to fill the gas tank is to prevent the fuel from going bad. If the tank is not full, there is air inside, which can cause the fuel to oxidize faster. This can result in the formation of varnish and other deposits in the fuel system, which can cause problems when the boat is started up again in the spring.
On the other hand, some boaters may argue that filling the gas tank is not necessary. One reason is that modern fuel additives can help prevent the buildup of moisture and the formation of deposits. Additionally, some experts suggest that leaving the tank partially full may help keep the seals and gaskets in the fuel system lubricated.
So, what is the right answer? Ultimately, it depends on personal preference and the specific circumstances of each boat. However, it is important to take some steps to protect the fuel system during winter storage. This can include using a fuel stabilizer, cleaning the fuel system, and storing the boat in a dry and covered location.
While there may be some benefits to filling a boat’s gas tank for winter storage, it is not necessarily a requirement. However, taking steps to protect the fuel system is important to ensure a smooth start-up in the spring. Consult with a marine mechanic or the manufacturer of your boat to determine the best course of action for your specific situation.
