in reply to the 2 bottom burned cyl. i would almost bet you got water back up thru the exhaust.could happen by coming off plane hard ,motor mounting to low ,excess water in bilge ,large wave hitting back of motor ,excess wieght on back of boat .seen it alot in my area ,people gather on back of boat at island to party ,drink and swim and flood to bottom cyl. also had a boat go into water no bottom plug and when he realized it started it up to put it back on trailer and burned two bottom cyls.this is also common on bracketed boats because the motor is so far off the back of boat it goes deeper than normal

Check the string gasket between the cyl. and the exhaust plate. Does the exhaust plate look clean where the exhaust comes out of the cyl. ? if the leak is on the exhaust side it will suck water in on the down stroke. It is unlikely the both head gaskets failed at the same time.
