Outboard

Did you check if you've got sparks?
If you leave the plug removed, but connected to its cable and firmly grounded (i.e. with the external metal part of the plug attached to engine), when you pull the starter cord you should see the sparks.
No signs of fire at all sounds like an electrical problem to me...
 
check the spark as per mapisM suggestion, If you're not getting a spark then check the electrical side starting with the emergency stop switch , ie check the clip/lanyard thing is correctly connected. If you are getting a spark but not firing then it could be a blocked carburettor jet, try spraying some carb cleaner through it (a lot).

We have a suzuki 6hp, which is very sensitive to old fuel, if you run 1 year old fuel through it, it blocks the carb jet, which stop the engine from firing. In our case just spraying carb cleaner down the carb isnt good enough, we have to dissasemble the carb and spray the carb cleaner directly onto/through the jet.

It could also be that it needs a hell of a lot of pulls to fire up the first time after a long layup.

When you pull the plugs out let us know if they are wet
 
If you raised a sweat, cussed a bit, got sympathy and bad advice from the neighbours as theirs started first pull and they looked smug if not gloating or worse they have one of those torqeedo jobbies ..... then you've just been initiated into the club.

Which is what really matters, at the end of the day.
As Maslow teached us, after reaching the top of his pyramid, we're all bound to come back to basics, rating physiological needs above anything else... :encouragement:
 
I had similar issues and it was cleaning the carb that caused the problem, The issue was that the gasket between the float chamber and the carb was letting in air so the fuel never properly got up to the chamber. I replaced the gasket at very small cost and it now starts and runs like clockwork

Applies to older engines, I think.
I have this exact situation on my 2005 Merc 5hp.
Random flooding, poor running.
New float bowl gasket arrives tomorrow :)
