So i have a 2001 Mercury 200hp efi. It is not an opti. When I first bought the boat it rand great but would only draw the tank to half before it died like it had no fuel. I teflon taped all the fittings made sure everything is tight. I have been having a problem where it's like someone pulled the killswitch while getting on plane or while running.down the lake. I have replaced cdm boxes and had one shop replace the high pressure fuel pump. Nothing has fixed the problem.
