My friends 200 merc suddenly died.he heard a clunk sound,alarm,then it shut itself down.gets fuel,good compression,no spark.i usually post on the OMC site and have some knowledge,not alot with MERC,Im wondering if he possibly had a failure of the oil injection system ,which would give him the alarm,would that also cut all spark?cranks fine,pistons up and down no problem,no sign of detonation.Thanks
