After running at various speeds and in the 190-210 degree ballpark on the temperature guage, my 1989 (350GM/OMC King Cobra) IO loses power and runs really rough (shaking, rumbling and even some banging) then she quits. It is a real nasty sounding event. This has happened twice now and I open the hatch, check the oil (clean and full), start her back up (starts and runs fine) then bring 'er back to the dock. Does this sound familiar to anyone?<br /><br />Regards,<br /><br /> --rml
