Where to Get Boat Fuel in Tampa Bay: Fuel Docks, Marina Gas, and Dockside Delivery

If you've ever idled in a fuel dock line on a Saturday morning in July, you already know the problem: fueling a boat in Tampa Bay isn't like pulling into a gas station. The nearest fuel dock might be a 25-minute run from your slip. The marina with gas near you might only carry 89 octane. And the pump price on the sign doesn't tell you what the fuel's been doing in that tank since the last delivery truck came through.

We fuel boats across Tampa Bay every day, so we see all of it. This guide covers the real options you have for boat fuel around the bay, what each one actually costs, and how to pick the right one for how you use your boat.

Your Real Options for Boat Fuel in Tampa Bay

Most boaters in the bay are choosing between the same three, whether they think of it that way or not.

• Marina fuel docks — the traditional option. You run the boat to a marina that sells fuel, tie up, and pump. Works anywhere your boat can reach, but you spend time and fuel getting there.
• Gas stations — for trailer boats. Cheapest per gallon if you're towing anyway, with one big catch: most street pumps are E10 ethanol gas, which is a real problem in a marine tank that sits.
• Dockside delivery — the fuel comes to you. We run scheduled routes across St. Petersburg, Clearwater, Tampa, Tierra Verde, and Gulfport, fueling boats at their slips and lifts so the tank is full before you ever leave the dock.

Which one makes sense depends on where your boat lives and what it burns.

Marina Fuel Docks: What to Expect

Tampa Bay has a healthy spread of working fuel docks — municipal marinas like St. Petersburg Municipal Marina and Madeira Beach Municipal Marina, private facilities like Tierra Verde Marina, and dozens more up and down the Intracoastal. Most of them post their prices publicly, and we compile those listings every week into the live comparison further down this page — including the date each price was posted and whether a dock is reported closed or under construction.

A few things to know before you make the run:

• Gas and diesel don't always live at the same dock. Plenty of fuel docks are gas-only. Of the Tampa Bay docks publicly posting fuel prices right now, only about a third list a diesel price at all. If you run diesel, call ahead.
• Most docks reporting prices carry ethanol-free gas. That's the good news. Around the bay, 90-octane ethanol-free (the same spec as REC 90) is the standard at marine pumps, not the exception.
• Hours follow the office, not the sun. Many fuel docks shut down by 5 or 6 p.m., and the dock you're counting on at 6:30 p.m. on a Friday may already be locked.
• Weekends are the crunch, especially at the docks nearest the busy passes. On a holiday weekend, the line can eat a good chunk of your morning before you touch a pump.

None of that makes fuel docks a bad option. If your marina has one, or your favorite sandbar route runs past one, it's the simplest habit in boating. The costs show up when the dock isn't on your way — and for a lot of boaters in the bay, it isn't.

What Marina Gas Actually Costs You

The per-gallon number on the sign is only part of the math.

Start with the detour. If the nearest fuel dock is 20 minutes from your slip, a fill-up costs you 40 minutes of running time plus the fuel you burn to go get fuel — and depending on power, a center console on plane burns anywhere from 8 to 20 gallons an hour. Add the line when everyone fuels at the same time (Saturday mid-morning, holiday weekends, the hour before sunset cruises) and a "quick fill" can swallow a quarter of a short boating day. You don't get that time back.

Then there's the tank you can't see. Marina fuel sits in storage tanks between deliveries, and turnover varies a lot from dock to dock. Busy docks turn fuel quickly. Slower ones don't, and gas that sits in Florida heat and humidity is where water accumulation and fuel degradation start. Our fuel went into our tanks at the bulk terminal the same morning we pump it into yours. That's the difference; draw your own conclusion about what you'd rather burn.

And the price itself? Here's where the market actually sits: our REC 90 lands right in the middle of what Tampa Bay fuel docks charge for the same ethanol-free spec — just under the median as of this writing — and our diesel runs below the median of the docks that post one. We're not the cheapest pump in the bay and we're not the most expensive. The difference is what that same per-gallon dollar buys you: fuel loaded fresh that morning instead of fuel that's been sitting, delivered to your slip instead of a run across the bay, no minimums, and none of the costs in this section.

The comparison below compiles the prices Tampa Bay docks post publicly, refreshed weekly, with the date each price went up — because a posted price and the pump price on the day you show up aren't always the same number. If a dock is reported closed or under construction, the table flags that too. When in doubt, call before you make the run.

Trailer Boats: Gas Stations and Ethanol-Free Pumps

If your boat lives on a trailer, the math changes. You're towing past gas stations anyway, and street fuel runs meaningfully cheaper than anything on the water.

The catch is ethanol. Standard 87 octane at a street pump is E10 — 10% ethanol — and ethanol in a marine fuel system attracts water, degrades in storage, and can phase-separate into a layer your engine cannot burn. A boat that burns through its tank every week has much less to worry about; it's the boat that sits between trips that pays. We've written a full breakdown of why ethanol destroys marine engines if you want the chemistry.

Some stations do carry ethanol-free gas at a premium, usually badged as recreation fuel or REC 90, and finding them is the trick. We keep a running local list in our guide to finding ethanol-free gas in Tampa Bay. For smaller boats, there's also the old-school move: fill portable tanks at an ethanol-free pump and carry them down to the boat. Unglamorous, works fine at six-gallon scale.

Full transparency on one more option: a few delivery services around the bay run land-side fuel trucks that can fill trailered boats and dry storage. We don't — our delivery runs by boat, to boats in the water — but if your boat lives on a trailer and you want fuel brought to it, that category exists and it's worth knowing about. If you're not sure what REC 90 actually is or whether your boat needs it, start here.

The Dockside Alternative: Fuel That Comes to You

Delivery is the one option where the boat stays put. You schedule a fill in the Mobile Marina app or by phone at (727) 761-1173, and our fuel boat meets yours at your marina slip, your lift, or your dock at home. Our routes cover St. Petersburg, Clearwater, Tampa, Tierra Verde, and Gulfport on a set schedule, so your fill lands on the day your area runs. The fuel goes into our tanks at the bulk terminal that same morning — it never sits in storage between deliveries.

We carry two products: REC 90 ethanol-free gasoline and marine diesel. REC 90 is the right call for most gas outboards in this climate because it takes ethanol's water-chemistry problems off the table — not because it's magic, just because it removes the ingredient that causes them.

One honest caveat: delivery runs on scheduled routes, not on a whim, so it rewards boaters who fill on a regular cadence — most set a standing schedule with enough buffer that running dry mid-week never comes up.

We're also not the only outfit delivering fuel on the bay anymore. Some services run land-side fuel trucks, and if you're comparing them against our fuel boat, here's where the difference actually shows up:

• Regular routes you can plan around. Our routes run on a set schedule, so your fill lands on a predictable day — no calling around to see when a truck can make it out.
• No minimums. A small bay boat gets the same stop as a big sportfish.
• No property access needed. We come by water. Nobody needs your gate code, your driveway, or a truck parked in your yard — if your boat's on the water, we can reach it.
• Scheduling in the app, not on the phone. Set up a delivery in a couple of taps, or put it on a standing schedule and stop thinking about fuel entirely. No call required each time.

Fuel Dock vs. Dockside Delivery: Which Makes Sense for You

There's no single right answer — it depends on how your boat lives.

The pattern in that table is the whole argument: the price column is a wash, and every other row tips one way. A fair rule of thumb still applies — if your marina sells fuel forty steps from your slip, use it. For everyone else, run your own numbers in the calculator below: put in your dock's address and see what the trip to your nearest fuel dock actually costs in time and burned fuel.

The Bottom Line

Fueling a boat in Tampa Bay comes down to three options: run to a marina fuel dock, haul the boat past a gas station, or have the fuel come to you. The docks work fine when one's on your way, and the street pump works if you've solved the ethanol question. For everyone whose boat lives at a slip, a lift, or a dock at home, scheduled dockside delivery means the tank is already full when you step aboard — which is the whole point. Our job is keeping you on the water, not in line for it.
