Air box, I assume you mean cowl (?)
yes and the covers over the carb intakes.
 Direct into the carbs or intakes.

I know this is old, but I had a similar problem with an old merc. I was told it was the scroll seals, the seals between a pair of cylinders where they shared a carb. The alloy block had Reed valves to allow fuel air mixture to either cylinder. These blocks had a close clearance on the crank to prevent fuel air mixture passing along the crank instead of being forced up in to the combustion chamber. This is made worse when the motor is well immersed in water and the exhaust is restricted.
you can't fix an idiot with duct tape, but it does muffle them for a while...
