Use a piece of rubber hose that fits snug over the end of the spark plug and use this to start the spark plugs. Also use anti-seize on the threads of the spark plug. FYI, a little ant-seize goes along way. Make sure the spark plugs thread in all the way, before you put any type of tool on them. If this does not work it may be easier to remove the bottom cowling on all Mercury 2.5L Opti's.
