Its doubt-full it has to do with air fuel mixture, more like fuel oil mixture or the rings are worn. If the engine has had an overheat problem in the past that would also contribute to your problem.

It could be too lean or you could have just revved the balls off it, Two stroke engines are prone to piston failure.

Lean will definitely mess up a piston.

if it's a John/Rude outboard, piston failure is common in the '70's. stopped up high speed jet in a carb. can lean a cylinder out & cause the same damage.

If it was to lean you would not have physical damage. I would say it is the timing. Timing could cause damage.
