A Boat's Biggest Fuel Concern: Removing Water from Fuel Tank

Water can get into the boats fuel tank in several ways, from condensation in the tank, ingress from a crack in the fill cap, and from the natural water content in today’s biodiesel. If left, water in fuel on the boat causes diesel “bug” sludge which blocks filters, damages pumps and then gets pulled into the boat’s fuel system which can lead to potential engine failure, fuel system corrosion and poor fuel efficiency.

However the water in the fuel on your boat got in there, it needs to be acted on quickly. Let’s look at the symptoms of having water in the fuel and then the solution!

The performance of a boat’s engine will be noticeably reduced if water has entered or condensed in the fuel tank. This can show as trouble accelerating and getting the boat up to speed, engine hesitation with a spluttering sound, and the final tell-tale sign: cloudy or milky fuel.

it is good practice to take a sample of your fuel and check for the presence of water from your tank. Water can appear in fuel in 3 different ways:

If the water in fuel on your boat is left and not dealt with, it will corrode the engine and fuel system, and can result in a nasty diesel bug sludge that blocks pipework and causes costly damage and downtime to the boat after refuelling. Keeping the tank almost full of fuel to reduce the amount of condensation can help but filling it more than 95% won’t allow for expansion.
