I have a friend that just had the same problem with an older Evinrude. Turns out he did not have enough of a charge in the battery to crank engine to spark with plugs in. He took the battery out of his car and hooked it up and voila......started right up. Funny thing is that when he hooked up the boat battery again, it started. The best we could figure out was that he had a little corrosion somewhere on the connections and by disconnecting his battery, he seemed to have cleaned it. Not sure if this is what is wrong with yours but definitely worth a look. The motor needs a certain amount of power to send spark to plugs when plugs are in the motor. Very strange...
