    1999 Mercury 175 EFI

    Motor just starting idling a little rough when I come off plan to idle then cuts off. I can start motor back up but if it stays idle it bogs down it seems and cuts back off. If I start motor and give it gas and start hauling it runs great. Any ideas? Thanks I’m advance! Serial # OG898853
