How To Clean a Boat Carburetor

The carburetor is an important part of your boat's engine. It mixes together air and water for the engine's internal combustion. Proper cleaning and maintenance is crucial to keep your carburetor in good condition to help you save on fuel and maintenance costs. Read on and find out how you can clean your boat's carburetor with these super easy steps.

Remove the fuel-water separator filter. The most common problem encountered with a dirty carburetor is engine stalling. This usually happens when the carburetor jets become clogged up with automotive fuel additives. The first thing that you have to do is to remove the fuel and water separator filter.

  • You can generally find the filter in between the pump and the carburetor or the fuel injection tank.
  • Check the user's manual on how to detach the fuel/ water separator filter for your boat's engine model. But generally, detachment is rather easy, you just need to unscrew a couple or so bolts located at the top or the sides of the filter and simply pull it out.

Inspect the filter. Inspect the fuel- water separator filter for gunk or glop that may have built up around the rim or other parts of the filter. Remove the dirt and fragments that might have clung into the filter using your hand.

  • Be sure to wear protective gloves to prevent getting stained with grease and grime, which are very difficult to clean.
  • Take the carburetor and place it on a clean, flat surface.
  • Inspect the separator filter once again then gently wipe the surface with a dry, clean cloth.

Fill the fuel-water separation filter with a cleaning formula. Make sure that the carburetor cleaning formula, preferably solvent based, has a fast penetrating capacity. This will effectively dissolve and remove gum or dirt deposits in the filter. Make sure that the entire carburetor filter is filled with the cleaning solution. You can find a multitude of heavy duty carburetor cleaning formulas in local automotive repair shops.

  • Attach the filter back to the engine and run it for one minute then turn the engine off. Pull out the filter and check if the cleaning formula is starting to come out of it.
  • Return the filter carefully and re-start the engine again for 15 minutes or until all the remaining cleaning formula comes out. Be sure to allow the engine to idle or cool for a bit within the 15 minute mark.

Be mindful of a few safety measures and additional tips to ensure a smooth procedure.

  • Always refer to the user's manual for additional details and information regarding your boat's engine.
  • Your work area must be well ventilated.
  • Wear your protective work uniform, such as gloves, cover-alls and goggles
  • Keep in mind that cleaning fluids and other chemicals are dangerous if mishandled. So make sure that you wear your protective gear when working with them and store them in a safe and locked place.

If the procedure goes well you will notice that the stalling will disappear and the engine will once again, run smoothly. Never fail to do a routine check up of your boat's engine and regularly inspect for leaks or tears in the tanks and reservoirs.
