The gas tanks on boat engines are the least glamorous part on the vessel. They may not be the most visually appealing and they don’t make a boat look faster or sleeker, but they are an integral part of the boat’s fuel system and they are necessary for the boat to run at full throttle. That said, they are one of the most important and expensive parts on the boat, so it’s important to get them right.
To help you find the right fuel tank, we’ve rounded up the best boat engine fuel tanks.

Best Boat Engine Fuel Tanks Buying Guide
Before choosing the best boat engine fuel tank you should consider following options:
1. Fuel Tank Capacity: Fuel tank capacity depends on the size of the engine and the size of the boat. The larger the engine and the smaller the boat, the greater the ratio of tank to engine.
Generally, if you have a larger engine with a smaller boat, the tank will be smaller in proportion to the engine. If you have a smaller engine with a larger boat, the tank will be larger as a proportion of the engine.
Therefore, if you have a small engine and a large boat, you will need a larger fuel tank. If you have a large engine in a small boat, you will not need as large a fuel tank.
2. Location: Where the tank is placed has a significant impact on the overall design of the boat. Fuel tanks are generally placed in the center or stern of the boat.
In the center, the weight of the fuel is evenly distributed, allowing for a smoother ride. Placing the tank in the stern of the boat ensures it is safely behind the center of buoyancy.
3. Fuel Tank Design: Fuel tanks come in two basic designs: integral and separate. An integral tank is one that is molded into the boat, often in conjunction with the water tank.
This is the traditional fuel tank design, the kind that most people probably imagine when they think of a boat fuel tank.
It is often cheaper to manufacture, but a disadvantage is that it can be difficult to carry out routine maintenance on the tank, and it can be difficult to get to. A separate fuel tank is one that is manufactured and installed separately from the boat. This often makes it easier to get to the tank for maintenance and cleaning.
However, it will add to the overall cost of the boat. For a speed boat, fuel tanks are often separate and placed in the bow.4. Fuel Tank Location: If the tank is placed in the center of the boat, then it will be easier to get to. However, it will add weight to the middle of the boat, which can affect the way the boat handles.
Fuel tanks in the bow are often integral, and therefore more difficult to get to. However, they will not add as much weight to the ends of the boat, so there will be less effect on the way it handles.
What else you should know about boat engine fuel tanks
1. What are the dimensions of a boat engine fuel tank?
There is no definitive answer to this question as it depends on the size and make of the boat engine. However, as a general guide, most boat engine fuel tanks are around 30-60 gallons in capacity.
2. How much fuel can a boat engine fuel tank hold?
The amount of fuel that a boat engine fuel tank can hold will vary depending on the size and make of the boat.
3. What is the weight of a boat engine fuel tank?
There is no definitive answer to this question as it depends on the size and make of the boat engine fuel tank. However, a good rule of thumb is that a fuel tank weighs approximately one pound per gallon of capacity. Therefore, a 10-gallon fuel tank would weigh approximately 10 pounds.
4. What are the construction materials of a boat engine fuel tank?
The fuel tank of a boat engine is typically made of stainless steel, aluminum, or polyethylene.
5. How is a boat engine fuel tank installed?
Boat engine fuel tanks are installed by attaching them to the boat’s hull with brackets or clamps. The tank is then filled with fuel and the engine is started.
Conclusion
On the market, there are numerous best boat engine fuel tanks. Hopefully, the list of the top ten best boat engine fuel tanks will save you time researching and deciding on the best one for you.
