I have a Mercury 2006 30hp 4 stroke that had an overheat alarm. The telltale runs strong at idle but quickly stops at higher rpms. New waterpump kits all OEM, which didn't help. Telltale starts almost immediately when dropped back to idle.
This condition has been repeatable on the lake and in water trough. Fresh water only motor. Don't know of this may be a clue to the problem but the telltale doesn't seem stop when up the idle speed when prop not engaged.
Other than this it starts excellent and runs like a sewing machine.
