Right from ngk
Pressure, compression call it you want what in the combustion chamber.they say
"A spark plug can deliver a weak spark (or no spark at all) for a variety of reasons...defective coil, too much compression with incorrect plug gap, dry fouled or wet fouled spark plugs, insufficient ignition timing, etc.
Slight misfires can cause a loss of performance for obvious reasons (if fuel is not lit, no energy is being created)"
And I went from memory on this.

Okay, we have enough info posted to basically end this thread....I think.
And since most boats are layed up for the winter, maybe some can chime in, I have a photo of different gaps, and was wondering which gap I'd run.
Hah !
