There's no way to know until you pull the heads. You could be looking at anything from an easy fix to one cylinder/chamber, replacement of one head, or a full rebuild if it wedged into a cylinder wall and gouged the bore. Once you have it down to be able to pull one head, it'd be silly not to pull the other one too, to eliminate any questions. Like Jerry said, on an air boat it should be easy access? Just don't drop stuff into the lake!
