i have a 1999 honda 130 motor and was cruising the open waters around 4500 rpm when all of the sudden the engine quit.i took off the cover and then took off the timing belt cover to discover my belts were like melted or shredded and the engine was hot . i called a honda dealer to check the warranty and they replyed it was mud daubbers in the timing belts made the engine jump time and thats what locked up the engine. i brought the boat to them and a week later they said was dirt daubers in that compartment. i said where are they ? honda said they cleaned them off already.well i took off the head since honda said it wasnt warrantied unless it was a cracked block or head.the honda dealer was not gonna check it out unless i paid 65.00 an hour.the head and valves appear to be ok but what made the engine burn the valves? theres no water in the oil and the cranck shaft turns the motor easy. have any clues to what happened?:
