Merc smartcraft showing engine malfunction
 

Anybody got any ideas on the smartcraft showing engine malfunction, i have a 600 sci all guages show fine- water pressure, water temp, fuel pressue , boost , oil temp /oil pressure all good the bell comes on with engine malfunction only . Fuel is good check filters no water in fuel boat running a little rough. Reset smartcraft , unhooked batteries still showing same code any ideas . Thanks

Can you give me your engine serial # and year model of the engine. Also is this engine malfunction displayed on your Vessel View or is it the round smartcraft gauges SC1000. If neither what smartcraft gauges do you exactly have.

I take this is NOT an OEM stock 600 sci engine from Mercury racing ? Looks like a stage II Whipple set up / PCM retune - is this correct and what else ?
