Frequently Asked Questions (FAQs)

1. Should you refuel portable tanks on the boat?

No, it is not recommended to refuel portable gas tanks on the boat. If you smell fuel or suspect any leaks, take the tanks ashore for refueling. It is important to wipe off any spillage before replacing them aboard the boat to ensure safety.

2. How do you carry extra gas on a boat?

There are a few options for carrying extra gas on a boat. You can use jerry cans or jerry jugs, which are common containers for carrying fuel. Another option is to use USCG-approved portable tanks designed specifically for boating. Additionally, there are portable or auxiliary fuel tanks available for this purpose.

3. What is the best way to fuel an outboard boat with a portable tank?

When fueling portable containers for an outboard boat, it is recommended to refill them on a stable surface like pavement or a dock to ensure a good ground. Avoid refueling on the bed of a truck or the deck of the boat as static electricity can build up and cause a spark. Placing an absorbent pad under the container while refueling on the dock is also a good practice.

4. Where should portable fuel tanks be stored on a boat?

All portable fuel tanks should be filled off the boat. Once filled, store the portable fuel tanks onboard in a well-ventilated area that is away from the engine and electrical equipment.

5. Is it better to winterize a boat with a full tank of gas?

Yes, it is recommended to winterize a boat with a full tank of gas. Filling the tank helps displace any air inside and prevents condensation from forming while the boat is in storage. This is particularly important if the boat is stored outdoors or in an unheated building.

6. Are fuel bladders safe on boats?

Yes, fuel bladders can be safe for boats. They are designed to provide a safe way to transport liquids, including fuel. Fuel bladders come in various sizes and can be suitable for different types of boats, ranging from fishing boats to yachts. It is important to choose a high-quality and properly designed fuel bladder for safe use.

7. How long can gas sit in a boat?

Boat fuel can go stale within 30 days, especially if it contains ethanol. Stale fuel can degrade and clog the fuel system. To extend the life of the fuel, it is recommended to top it up with fresh fuel regularly.

8. Should you leave the boat motor up or down?

The best practice is to leave the boat motor either on the boat or on an engine stand in an upright position, not tilted. If neither of these options is available, try to ensure that the engine is in an upright, self-draining position. If this is not possible, make sure the cooling system is completely drained.

9. When should a portable gas tank be filled?

All portable gas tanks should be filled off the boat to prevent spillage onto the boat and protect the environment. This also reduces the risk of fire or explosion. If you have a fixed tank onboard, make sure to ground the gas nozzle against the filler pipe for safe refueling.

10. Can you put gas station gas in a boat?

It is important to use non-ethanol gasoline to power your boat's fuel tanks. Ethanol in traditional unleaded gas can harm the rubber seals that keep the boat's engine waterproof. Using ethanol gasoline instead of non-ethanol gasoline increases the risk of water damage to the boat.
