Thanks for the question, Bob. Yes, you can use Sea Foam Spray to clean or fog an upper engine. If the engine has a carburetor, spray into the throat while the engine is running. If fuel-injected, spray into the throttle plate opening when running.
Sea Foam Spray will clean deposits, but it will not clean injectors. To clean injectors, add a high concentration of Sea Foam Marine PRO to a low amount of fuel and run it hard until almost empty before refueling.
