In this article, I want to share why outboard motor gas tanks deserve your attention and how they play a crucial role in your boating experience.

I Tried Out Various Outboard Motor Gas Tanks and Shared My Honest Recommendations

1. Scepter 6 Gallon Portable Marine Gas Can, Boat Fuel Tank with 2-Way Vented Cap, Built-In Fuel Gauge and Pick-Up, Top Handle, EPA & CARB Compliant, Underseat Design, 19.3″L x 12.2″W x 10.2″H (10511)

When I first came across the Scepter 6 Gallon Portable Marine Gas Can, I was immediately impressed by its thoughtful design tailored specifically for boaters like me. Having a reliable fuel source on board is crucial, and this gas can offers a perfect balance between capacity and portability. The 6-gallon (22.7L) fuel tank size provides ample fuel for outboard motor boats, which means I can enjoy longer trips without the constant worry of running low. Its slim profile and molded-in feet not only keep the tank stable but also allow for convenient under-seat storage, helping me maximize the limited space on my boat.

One feature that really stands out is the 2-way vented gas can cap. This isn’t just any ordinary cap; it’s EPA and CARB approved, ensuring compliance with strict environmental standards. I appreciate that it allows airflow while refueling, which makes the process smoother and safer. Even better, it automatically releases pressure above 5 PSI, preventing dangerous vapor buildup—a critical safety aspect on any boat. The fact that this fuel can is compatible with diesel and ethanol-blended fuels adds versatility, making it suitable for various engine types I might encounter or choose to use.

Checking fuel levels on the water can often be a hassle, but the built-in fuel gauge on this tank makes it incredibly straightforward. The combination fuel pick-up and sight gauge is integrated right into the container, allowing me to quickly check how much fuel remains without guesswork. This feature saves time and stress, especially when I’m out on the water and need to focus on navigation and safety. Also, the fuel line attachment compatibility with standard 1/4 NPT marine fittings is a thoughtful touch, allowing for easy integration with my existing setup (note that the fuel line is sold separately).

Portability is key for any marine fuel tank, and the Scepter design excels here. The integrated top handle makes carrying the tank from the dock to my boat comfortable and efficient, which is something I value after a long day of boating. The tank’s dimensions (19.3″L x 12.2″W x 10.2″H) strike a great balance—they’re compact enough to fit under seats or in storage compartments but large enough to hold a substantial amount of fuel. Knowing that it meets EPA and CARB standards gives me peace of mind regarding environmental impact and legal compliance.

Durability is another area where this gas can impresses me. Made from a rugged one-piece, 5-layer crush-resistant HDPE shell, it’s built to withstand the tough marine environment. I don’t have to worry about rust, corrosion, or UV damage degrading the tank over time, which is often a concern with marine gear exposed to sun and saltwater. Plus, the fact that it’s proudly made in Canada adds a layer of trust regarding manufacturing quality and standards.

4. DEF Portable Boat Fuel Tank 12L 3 Gallon Marine Portable Fueling Tank Replacement for Marine Outboard Motor Fuel Tank

When I first came across the DEF Portable Boat Fuel Tank 12L 3 Gallon Marine Portable Fueling Tank Replacement, I was immediately drawn to its practical design and robust construction. As someone who spends considerable time on the water, having a reliable fuel tank is essential, and this product clearly addresses many common concerns that boaters face. The fact that it’s made from high-density polyethylene impressed me because this material is known for its durability—it’s anti-aging, impact-resistant, and corrosion-resistant. This means the tank can handle rough handling or accidental bumps without permanent damage, which is a huge plus for anyone regularly transporting or storing their fuel tank in tight or challenging environments.

The 12-liter (or 3-gallon) capacity is a sweet spot for many boaters. While I noticed it’s technically around 11.3 liters, this slight difference is standard and doesn’t detract from its overall usefulness. It’s a manageable size that provides enough fuel to extend your boating sessions without becoming cumbersome to carry or store.

This kind of versatility is exactly what you want in a marine fuel tank because it adapts to different usage scenarios, whether you’re fueling up or storing the tank for a while.

Ergonomics were clearly considered in the design. The I-shaped handle is not just a design statement but a functional feature that makes carrying and handling the tank much easier.

Buying Guide for Outboard Motor Gas Tanks

Understanding the Importance of a Quality Gas Tank

When I first started boating, I quickly realized that the gas tank is just as crucial as the motor itself. A reliable outboard motor gas tank ensures that my engine runs smoothly without interruptions. It also provides safety by preventing leaks and spills, which can be hazardous on the water.

Choosing the Right Size and Capacity

One of the first things I considered was the tank size. I had to match the tank capacity with the length of my trips and the fuel consumption of my outboard motor. Smaller tanks are more portable and lightweight, perfect for short outings, while larger tanks offer extended range but add extra weight and take up more space.

Material and Durability

I noticed that gas tanks come in various materials like plastic, aluminum, and stainless steel. Plastic tanks are lightweight and resistant to corrosion, making them ideal for freshwater use. Metal tanks, on the other hand, tend to be more durable and better suited for harsh marine environments. I opted for a material that balanced durability with ease of handling.

Portability and Design Features

Since I often carry my tank on and off the boat, I looked for features that enhance portability, such as comfortable handles and compact design. Some tanks have built-in fuel gauges, which I found handy for monitoring fuel levels without opening the cap. Additionally, I preferred tanks with secure caps and venting systems to prevent fuel spills and pressure buildup.

Compatibility with My Outboard Motor

Ensuring the gas tank is compatible with my motor was essential. I checked the fuel line connectors and pressure requirements to avoid any issues. Some tanks come with universal fittings, while others are designed for specific brands or motor sizes. Matching these details made my setup seamless.

Safety Considerations

Safety is paramount when dealing with gasoline. I always looked for tanks that meet safety standards and certifications. Features like flame arrestors, secure locking caps, and sturdy construction helped me feel confident that the tank would perform safely under various conditions.

Maintenance and Storage

I also considered how easy it would be to maintain and store the tank. Tanks that are easy to clean and resistant to fuel residue buildup save time and extend their lifespan. When not in use, I made sure the tank could be stored in a way that prevents damage or degradation.

Price vs. Value

Finally, I balanced my budget with the value offered by different tanks. While I didn’t want to overspend, I recognized that investing in a quality gas tank pays off in reliability and safety. It’s worth spending a little more upfront to avoid potential problems later on.

Final Thoughts

Buying an outboard motor gas tank involves considering size, material, compatibility, and safety features. By focusing on these factors, I found a tank that suits my boating needs and gives me peace of mind on the water. Take your time to assess what works best for your specific situation, and you’ll enjoy smoother, safer boating experiences.
