Problem fixed: Engine wouldnt start

I recently bought a 21 trophy with twin outboards on it starboard engine ran but port side would crank but no start.thought it need a #2 coil but turned out to be a cdi box .changed that and got spark on that cyl. Still no start so started looking at timing and found tdc on cyl1 but the fly wheel timing marks were 90 off pulled the flywheel off .bingo no wooddruff key .Crowley marine had the key and were up and running thanks
