I recently purchased a 1994 400 Express Cruiser. My boat has twin 7.4 liter gasoline engines. I intend to replace the spark plugs on the two engines plus the plugs on the generator. How do I move/remove the helm and passenger seats to allow me to open the outside access hatches in order to access the outer spark plugs?
