How to Deal With Water in Boat Fuel Tank

No matter what model or how old boat you have owned, the engine despite being most of its time floating in the marine environment is not made to handle any amount of water inside it. If you’re a boating enthusiast or a marine professional, you may have heard of ethanol-blended fuel stories. There are plenty of articles available on the web where you can dive out and read how ridiculously it attracts water and damages the interior of your boat gas tanks.

Some boaters face serious issues when they store fuel that contains ethanol. Water in fuel means it can rust your Grady white tanks, cause poor acceleration, and can cause complete engine breakdown if it is present in large volume.

Having been in the marine industry for more than 41 years, Atlantic Coastal Welding has established a reputed name in building and repairing fuel tanks for different boat models including Grady White, Mako, Angler, Boston Whaler, Bertram, and more to name.

Though we have published on this topic earlier as well, in this blog, we will guide you on how you can deal with water in your boat gas tanks.

You might probably aware of the problems that water can create, ranging from corroding your aluminum fuel tanks to clogging carburetors, to forming algae and bacteria in the tank. Overall, water is a big concern and if you have recently noticed it around/inside your tank you should take appropriate action sooner.

• If you have accidentally/unknowingly filled your fuel tank with water, the best way is to use a quality fuel additive product. A fuel additive can separate water and fuel. Once the water settles at the bottom and fuel pops up on the top of the tank, you can utilize an oil-change pump to remove all of the water.
• Some tanks are designed with a valve at the bottom that allows you to drain off water easily without wasting any fuel.
• You can prevent most water problems by simply opting for fuel that does not contain more than 10 percent of ethanol (E10 gasoline).

While in large-scale commercial boating, users may prefer to completely drain off all the fuel and put fresh in, for normal boaters it may not be a feasible solution.

There are multiple ways you can deal with water in your boat fuel tank. However, we would strongly recommend you first consult an experienced professional before doing any treatment alone. This will help you avoid any accident which is possible due to the hazardous quality of any fuel.
