    2005 Crownline Fuel System Charge/Prime on key turn

    Thanks. The simplicity of wiring color, which I didn't even think about while at the boat. I will get there this week. I have not found much specific to the OSX, everything is GX. It seems the main difference is the composite sterndrive. OS is for their Ocean Series.
