      Boat Gas Caps

      Some boat owners will take the trouble to use fuel additives to protect their gas from deteriorating, but overlook a leading cause of fuel contamination: water seeping in from failed boat gas caps. Since these components are your fuel line (and engine’s) first line of defense, it makes sense to ensure that they are in good working order. Make checking your boat’s gas cap part of your pre- and post-trip maintenance. Since rubber components like O-rings degrade over time, it is important to check your gas cap after every trip and replace the gas cap’s rubber parts once a year.
