How To Clean Out Outboard Fuel Injectors

Outboard motors are, for the most part, found on boats and marine vehicles. Outboard fuel injectors distribute fuel to individual cylinders on two-stroke and four-stroke outboard motors. If the fuel injectors are not cleaned and well maintained, the injectors can collect carbon build-up and prevent a smooth distribution of fuel. This can, in turn, lead to poor performance. Cleaning your outboard fuel injectors with outboard two-stroke or four-stroke fuel injector cleaner will keep your outboard motor performing at it's best.

Instructions

  1. 1

    Remove the gas cap to your outboard motor. Turn the gas cap counter-clockwise to loosen the cap and pull the gas cap off of the fuel tank.

  2. 2

    Fill your gas tank with gasoline. If your boat requires a mixture of oil and gasoline, such as for two-stroke engines, refer to your owner's manual to find the correct ratio of oil and fuel for your engine model.

  3. 3

    Pour the entire bottle of outboard fuel injector cleaner into the full fuel tank.

  4. 4

    Place the fuel cap back on the outboard motor fuel tank. Twist the cap clockwise to tighten and secure the cap to the fuel tank.

  5. 5

    Start the boat motor. The outboard fuel injector cleaner will automatically clean the fuel injectors once the motor has been turned on and fuel is distributed into the cylinders.
