When I first came across the AloneGoer Portable Boat Fuel Gas Tank, I was immediately drawn to its practical size and compatibility with Yamaha outboard motors. The 12-liter (or 3-gallon) capacity strikes a great balance between carrying enough fuel for extended trips and keeping the tank lightweight and manageable. As someone who enjoys boating but also values convenience, this tank’s size felt just right for day outings without the bulk of larger tanks that can be cumbersome to handle.

One of the standout features for me is the tank’s compatibility with Yamaha motors, specifically the replacement of the Yamaha part number 6YL-24201-24-00. This means that if you own a Yamaha outboard engine, you can be confident that this fuel tank will fit seamlessly with your setup. The inclusion of a marine fuel line connector hose designed for outboard engines over 6 HP adds to the ease of installation and use, which is crucial when you want to spend more time on the water and less time fiddling with equipment.

This venting system allows for air pressure balance inside the tank, which helps maintain a smooth flow of fuel to the engine and prevents vacuum lock. In real-world terms, this means your engine is less likely to sputter or stall due to fuel flow issues, an essential factor when you’re out on open water and depend on reliable performance.

Dimension-wise, the tank measures 36.5 cm in length, 27.5 cm in width, and 26 cm in height, making it compact enough to fit comfortably in most boat compartments without taking up excessive space. Given its capacity and size, the tank suits a wide range of small to medium-sized boats, especially those using Yamaha outboards. It’s a well-thought-out size that meets practical needs without unnecessary bulk.

One of the standout features for me is the 2-way vented gas can cap. Knowing that it’s EPA and CARB compliant gives me peace of mind about environmental safety and regulatory adherence. The vented cap’s ability to allow airflow during refueling while automatically releasing pressure above 5 PSI is an intelligent safety mechanism that prevents dangerous vapor buildup—a concern I had with older gas cans. Moreover, its compatibility with diesel and ethanol-blended fuels adds versatility, so I can confidently use it regardless of the fuel type my boat requires.

The built-in fuel gauge is another feature that immediately caught my attention. It’s frustrating to guess how much fuel is left during a trip, but this combination fuel pick-up and sight gauge eliminates that guesswork. Being able to quickly check fuel levels without opening the tank or using separate tools adds convenience and efficiency. The fact that it accepts standard 1/4 NPT marine tank fittings means I can easily integrate it with existing fuel lines, making setup straightforward. Although the fuel line is sold separately, the design accommodates all the essentials I need for a smooth boating experience.

When I first came across the attwood 8803LP2 EPA and CARB Certified 3-Gallon Portable Marine Boat Fuel Tank, I was immediately impressed by its thoughtful design tailored specifically for boaters like me who prioritize safety, compliance, and convenience.

This construction not only boosts durability but also enhances safety by reducing the risk of leaks or failures under pressure. As someone who has seen less robust tanks wear down over time, this gives me peace of mind, especially during longer trips or rougher conditions.

The built-in vacuum valve in the cap is another thoughtful addition that I really appreciate. Traditional fuel tanks often require manual venting to prevent pressure buildup, which can be a hassle and a safety concern if overlooked. This vacuum valve eliminates the need for me to manually vent the tank, simplifying operation and reducing the chance of user error. It’s these small but smart features that really elevate the user experience and make fueling less of a chore.

Compatibility is crucial when it comes to marine fuel tanks, and this product supports ¼-inch NPT fuel fittings, which are widely used and easy to source.

This peace of mind allows me to focus on enjoying the scenery and the calmness of the water rather than constantly checking my fuel levels.

Buying Guide for Gas Tank for Outboard Motor

Understanding the Importance of a Good Gas Tank

When I first started using an outboard motor, I quickly realized how crucial the gas tank is for a smooth boating experience. A reliable gas tank ensures that fuel flows consistently to the engine, which helps avoid stalls or interruptions while on the water. Choosing the right tank not only affects performance but also safety.

Consider the Tank Capacity

One of the first things I looked at was the capacity of the gas tank. Depending on how long I planned to be out on the water, I needed a tank that held enough fuel without being too bulky or heavy. Smaller tanks are easier to carry and store but require more frequent refueling. Larger tanks provide extended range but can add weight and take up more space.

Material and Durability

I paid close attention to the tank’s material. Most gas tanks for outboard motors are made from plastic or metal. Plastic tanks are lightweight, resistant to corrosion, and easier to handle. Metal tanks tend to be more durable but can be heavier and prone to rust if not properly maintained. I made sure to choose a tank that could withstand the marine environment and last through many seasons.

Portability and Design Features

Since I often transport my motor and tank separately, portability was a key factor. I looked for tanks with ergonomic handles and a compact design that fit well in my boat’s storage compartments. Some tanks also come with built-in fuel gauges, which I found helpful to monitor fuel levels without opening the cap.

Fuel Line and Connection Compatibility

Ensuring the gas tank is compatible with my outboard motor’s fuel line was essential. I checked the type of fuel connectors and hose fittings to avoid leaks or connection issues. Many tanks come with standard fittings, but it’s always good to verify before purchasing.

Safety Features

Safety can never be overlooked. I looked for tanks with secure caps that prevent fuel spills and vapor leaks. Some tanks have venting systems to avoid pressure build-up, which adds an extra layer of safety. A well-sealed tank also reduces the risk of fuel contamination.

Maintenance and Cleaning

I considered how easy it would be to clean and maintain the tank. Tanks with wide openings are easier to rinse and dry, which helps prevent fuel residue buildup and prolongs the tank’s life. Regular maintenance keeps the fuel fresh and the motor running smoothly.

Price vs. Quality

Finally, I balanced price with quality. While I didn’t want to overspend, I knew that investing in a well-made gas tank would save me money and hassle in the long run. Cheap tanks might seem like a good deal but can lead to problems like leaks or premature wear.

Final Thoughts

Choosing the right gas tank for my outboard motor made a significant difference in my boating trips. By considering capacity, material, portability, compatibility, safety, and maintenance, I found a tank that fits my needs and gives me peace of mind on the water. I recommend taking time to evaluate these factors before making your purchase.
