1989 390 express with 7.4 340 hp gas powered, hurth trans cc port & star
I have owned the boat for 3 years, the port engine has always consumed about 20 % more fuel than the starbord engine. without operating the jenny, both engines are tuned up and run great, both props have been refurbished, carbs are original, both chokes are fully open when at operating temp, ignition timing is set the same, spark plugs have good color and look alike! :huh: Any thoughts!
