Marine Fuel Delivery in Florida — Diesel & Gas for Boats
Marine fuel delivery to Florida docks, marinas, and waterfront facilities. Marine diesel, marine gas oil, and gasoline for recreational and commercial vessels statewide.
What Is Marine Fuel?
Marine fuel encompasses the diesel and gasoline products used to power boats, yachts, commercial vessels, and watercraft. BettyJet delivers marine diesel oil (MDO), marine gas oil (MGO), ultra-low sulfur marine diesel, and marine gasoline to marinas, docks, and waterfront facilities throughout Florida.
Marine fuels differ from their automotive counterparts in several important ways. Marine diesel specifications (ISO 8217) require a higher flash point — 140°F minimum compared to 125°F for automotive diesel — because of the fire safety requirements aboard vessels. Marine diesel also typically has higher lubricity, which protects the fuel injection systems in marine engines that operate under sustained high loads.
Marine Diesel Oil (MDO) is a distillate-based fuel that may contain a small amount of residual fuel oil. It conforms to ISO 8217 DMB specifications and is commonly used in medium-speed marine diesel engines.
Marine Gas Oil (MGO) is a lighter distillate fuel conforming to ISO 8217 DMA specifications. It is the cleanest marine diesel grade and is required in Emission Control Areas (ECAs) where sulfur content must not exceed 0.10%.
For recreational boats and smaller vessels, standard ULSD is commonly used and is perfectly suitable. Many Florida marinas dispense standard ULSD rather than specialty marine diesel, as modern recreational marine engines are designed to run on it.
Marine gasoline poses unique challenges in Florida's humid climate. Ethanol-blended gasoline (E10) can absorb moisture from the air, leading to phase separation — where the ethanol and water separate from the gasoline and sink to the bottom of the tank. This water-ethanol mix can damage engines and fuel systems. Ethanol-free gasoline is strongly recommended for all marine applications.
Florida's coastline stretches over 1,350 miles with hundreds of marinas, boatyards, and port facilities. BettyJet delivers marine fuel to facilities on both the Gulf Coast and Atlantic Coast, from Pensacola to the Florida Keys.

How BettyJet Delivers Marine Fuel
Delivery Method
Tanker truck delivery to dockside fuel tanks, marina storage facilities, and waterfront locations. For large vessels, we coordinate direct fueling at port facilities.
Minimum Order
500 gallons (may vary by fuel type and location)
Storage Notes
Marine fuel tanks should be equipped with water-separating filters and regularly inspected for water intrusion and microbial contamination. Florida's humid climate accelerates water condensation in fuel tanks. Use biocide treatments for long-term diesel storage. Ethanol-free gasoline is recommended for marine applications to prevent phase separation in boats.
Marine Diesel vs Automotive Diesel
| Property | Marine Fuel | Automotive ULSD |
|---|---|---|
| Sulfur Content | Varies (up to 0.50% non-ECA) | Less than 15 ppm (0.0015%) |
| Flash Point | 140°F minimum (safety at sea) | 125°F minimum |
| Standard | ISO 8217 | ASTM D975 |
| Lubricity | Higher (protects marine engines) | Lower (additives may be needed) |
| Water Tolerance | Designed for marine environment | Sensitive to water contamination |
| Availability | Specialty marine suppliers | Widely available |
Marine Fuel Frequently Asked Questions
What is the difference between marine diesel and regular diesel?
Marine diesel (MDO/MGO) is formulated to ISO 8217 standards with a higher flash point (140°F vs 125°F for safety at sea) and better lubricity for marine engine components. While many recreational boats can run on standard ULSD, dedicated marine diesel provides better protection for marine engines exposed to the harsh saltwater environment.
Should I use ethanol-free gasoline in my boat?
Yes, ethanol-free gasoline is strongly recommended for marine applications. Ethanol attracts water (hygroscopic) and can cause phase separation in marine fuel tanks, leading to engine damage. Boats are especially vulnerable because fuel tanks are exposed to temperature swings and humid marine air. BettyJet can supply ethanol-free marine gasoline where available.
Does BettyJet deliver fuel directly to marinas?
Yes. BettyJet delivers diesel and gasoline directly to marina fuel storage tanks, private docks, and waterfront facilities throughout Florida. We serve both the Gulf Coast and Atlantic Coast. Call (813) 694-8898 to set up marina fuel delivery.
What Florida ports and marinas does BettyJet serve?
BettyJet serves marinas and waterfront facilities statewide — from Pensacola and Destin on the Gulf Coast to Jacksonville, Daytona, Fort Lauderdale, and Miami on the Atlantic. We also serve Tampa Bay, Clearwater, Sarasota, Naples, and the Florida Keys. Contact us for delivery to your specific location.
How do I prevent water contamination in my marine fuel tank?
Install water-separating fuel filters, keep tanks as full as practical to reduce condensation, inspect tanks regularly for water accumulation, use fuel biocide treatments (especially for diesel stored more than 30 days in Florida's humid climate), and drain water from filter bowls before each use. BettyJet delivers clean, quality-tested fuel to minimize contamination risk.
