The size of a boat's fuel tank is an important consideration for any prospective buyer. Fuel tank sizes vary depending on the boat's size and intended use. For example, most 20-foot saltwater fishing boats have fuel tanks ranging from 40 to 80 gallons. Tidewater, a renowned boat manufacturer, offers a range of fuel tank capacities in their models, with some owners reporting tanks ranging from 19 to 100 gallons. The Tidewater 3100 Carolina Bay, for instance, has a fuel load capacity of 60 gallons. While a larger fuel tank may be advantageous for extended trips or hurricane preparedness, it's essential to consider factors such as engine size, fuel efficiency, and personal usage patterns when determining if a boat's fuel tank is big enough.

What You'll Learn
The Tidewater 3100 Carolina Bay has a 60-gallon fuel tank
The Tidewater 3100 Carolina Bay is a fishing boat that can also be used for comfortable cruising. It is hailed as the world's largest bay boat. It has a fuel tank capacity of 220 gallons. This is a large fuel tank, with most 20-foot saltwater fishing boats having a fuel tank capacity of 40-80 gallons.
The Tidewater 3100 Carolina Bay has a pair of Yamaha F350 V-6s on the transom, which allow the boat to reach a top speed of over 66 mph. When paired with twin 400 hp Mercury V-10s, the boat exceeds 70 mph. The double-stepped hull helps to improve fuel economy at speed.
The boat has a shallow deadrise that tapers to 17 degrees at the transom, which helps the boat get skinny. The boat has a finished head in the console, complete with a pump-out toilet. The bow seating behind the casting platform is recessed for passenger safety, and the backrests can fold out of the way for fishing. The cushions are held in place with magnets, so they can be quickly removed.
The Tidewater 3100 Carolina Bay also has a freshwater tank capacity of 19 gallons. This is connected to a shower nozzle built into the starboard side of the T-top.

Smaller tanks are preferable to larger ones to avoid fuel degradation
The size of a boat's fuel tank is an important consideration for any boat owner. While a larger fuel tank means fewer refuelling stops, smaller tanks have their own advantages. For example, a smaller tank that needs refilling each time the boat is used is preferable to a larger tank that only needs filling every three outings. This is because fuel can degrade over time, losing its octane rating in less than six months, and becoming contaminated with water and moisture.
Fuel degradation can lead to costly repairs. Water intrusion, for example, can cause algae and microorganisms to grow, leading to the build-up of black slime that can block pumps and filters. Water can enter a fuel tank through rainwater or condensation, and it is important to establish a process for monitoring and removing it.
Smaller fuel tanks are also beneficial when it comes to selling a boat. A boat with a disproportionately small fuel tank may be considered unviable by prospective buyers. A 20-foot boat with a 140 HP engine and a 19-gallon tank, for instance, may be viewed as inadequate despite being sufficient for the owner's usage.
The material of a fuel tank is another important consideration. Fuel tanks are typically made from stainless steel, polyethylene, or fiberglass. Polyethylene tanks are resistant to ethanol-related degradation and are a good choice for small engines. For larger tanks, steel provides superior impact protection.
In summary, smaller fuel tanks are preferable to larger ones to avoid fuel degradation. Smaller tanks also have other benefits, such as being less likely to affect the resale value of a boat and being made from materials that resist degradation. By choosing a smaller tank and refuelling more often, boat owners can avoid the issues associated with degraded fuel and the costly repairs that may result.

2-stroke engines burn more fuel than 4-stroke engines
The size of a fuel tank on a Tidewater boat varies depending on the model. For instance, a 2003 SeaSkimmer boat that is 20' long and 9' wide can fit a 19-gallon fuel tank. On the other hand, a Tidewater owner mentioned having a 60-gallon fuel tank on their boat, which is considered large enough to make at least 3-4 trips without needing to refuel.
Now, regarding the comparison of 2-stroke and 4-stroke engines, it is often claimed that 2-stroke engines burn more fuel than 4-stroke engines. This belief is supported by some sources, which state that 2-stroke engines are less fuel-efficient and consume more fuel to produce the same amount of power as 4-stroke engines. This is due to the fact that 2-stroke engines require oil to be mixed with the fuel, resulting in a higher amount of oil being burned during the combustion process. Additionally, 2-stroke engines have a broader power band and better "breathing" capabilities, which contribute to their higher fuel consumption.
However, it is important to note that the fuel efficiency of 2-stroke and 4-stroke engines depends on various factors, including engine specifications, boat size, and operating conditions. Some sources suggest that in certain situations, a 2-stroke engine can match or even exceed the fuel economy of a 4-stroke engine. For example, 2-stroke engines are more fuel-efficient when run at or just above idle and above three-quarter throttle, as the fuel is monitored more precisely. Additionally, direct injection systems in 2-stroke engines can improve their fuel efficiency.
The choice between a 2-stroke and a 4-stroke engine depends on factors such as performance requirements, maintenance preferences, and environmental considerations. While 4-stroke engines have gained popularity due to their improved fuel economy and reduced emissions, 2-stroke engines offer advantages such as simpler design, lighter weight, and lower cost. Ultimately, the decision should be based on the specific needs and preferences of the boat owner, as there is no one-size-fits-all solution.
In conclusion, while it is generally believed that 2-stroke engines burn more fuel than 4-stroke engines, the actual fuel consumption depends on a variety of factors. Tidewater boats are equipped with fuel tanks of varying sizes, and the suitability of the tank size depends on the intended usage and preferences of the owner.

A 19-gallon tank is enough for a 20-foot boat with a 140 HP motor
A 19-gallon fuel tank may be enough for a 20-foot boat with a 140 HP motor, depending on how you plan to use the boat. Fuel consumption for boats is measured in gallons per hour, and it depends on a variety of factors, including the boat's horsepower, the weight or load on the boat, the vessel trim, and sea conditions.
To calculate the approximate fuel consumption of a boat, you can use the formula: (horsepower rating x fuel consumption average) / fuel weight. For example, a 150-horsepower engine will use about 15 gallons per hour. However, these figures are averages and can vary by up to 20%.
Additionally, the type of engine can also impact fuel consumption. 2-stroke engines, for instance, burn a lot more fuel than 4-stroke engines. A well-maintained 4-stroke gasoline engine will burn about 0.50 pounds of fuel per hour for each unit of horsepower, while a 4-stroke diesel engine will burn about 0.4 pounds of fuel per hour for each unit of horsepower.
While a 19-gallon fuel tank may be sufficient for short trips or leisure fishing, it may not be considered "viable" by potential buyers for a 20-foot boat with a 140 HP motor. Most 20-foot saltwater fishing boats have larger fuel tanks, typically ranging from 40 to 80 gallons. A larger fuel tank can provide a greater range and reduce the frequency of refuelling, which can be advantageous for longer trips or more serious fishing excursions.
Ultimately, the decision on whether a 19-gallon fuel tank is enough depends on the specific usage and requirements of the boat owner. Some boaters may prefer a larger fuel tank for extended trips or to serve as a fuel storage container during emergencies, such as hurricanes.
