Marina Fuel Price Finder

Marina fuel typically costs $1-2 more per gallon than road fuel. As of early 2026, marina gas prices range from $4.50 to $6.50 per gallon and diesel from $5.00 to $7.00, depending on region and location. Florida marinas average around $4.75-5.50 for gas, while the Northeast and West Coast tend to be higher at $5.50-6.50 for gas. Prices vary by season, with summer months often seeing the highest rates due to increased demand.

Marina fuel costs more due to several factors: delivery logistics (fuel must be transported to waterfront locations by specialized trucks or barges), lower sales volume compared to gas stations, higher insurance and environmental compliance costs for waterfront fueling, specialized equipment like fuel docks and spill containment systems, and the convenience premium of fueling directly at the water. Marinas in remote or island locations tend to have the highest markups.

Marina gasoline is generally the same grade as gas station fuel, though many marinas offer ethanol-free (E0) fuel which is preferred for marine engines. Ethanol can attract moisture and cause corrosion in marine fuel systems. Marina diesel is the same ULSD (Ultra Low Sulfur Diesel) available at gas stations. The key difference is availability of ethanol-free options and the convenience of dockside fueling.

Ethanol-free fuel is recommended for marine engines, especially for boats that sit unused for extended periods. Ethanol (E10) can absorb water from humid marine environments through a process called phase separation, which can damage fuel systems, corrode aluminum components, and degrade fiberglass fuel tanks. While modern outboard engines are designed to handle E10, ethanol-free fuel provides better performance and fewer maintenance issues for most boats.

Fuel consumption varies dramatically by boat type. A small fishing boat with a 90hp outboard uses about 7-9 gallons per hour at cruising speed. A 25-foot center console with twin 150hp engines burns 15-25 GPH. Pontoon boats are more efficient at 3-6 GPH. Large cabin cruisers can consume 20-50+ GPH. Sailboats under auxiliary power use only 1-3 GPH. For planning purposes, multiply your engine's GPH at cruising RPM by your expected hours on the water.
