I have a 2002 Mercury Saltwater series 200 hp 2-stroke. We took it out of the water a couple months ago to do off season painting, cleaning, and put a new prop on. It wasn't started for a month or so and now I can't start it. I put new plugs in after checking the block plate to be sure of plug spec. I suspected fuel so I drained the gas in the engine and hooked up a gas can with fresh fuel. The firing order must be right as the plugs have a very short wire to the each coil. The engine will sputter, attempt to start, but never get going. I tried ethyl-ether starting fluid with no difference. I am totally lost now. Any ideas?
