    225 Ox66 idling poorly

    This engine runs strong but won't idle at all. Any ideas?

    If you've never done the fuel system maintenance, work through that list as it needs to be done anyway. Onboard water separator filter, LP fuel pumps, VST filter, clean O2 sensor, and send the injectors to Brucato for a clean and calibrate. Check this list against the 'official' list on simyamaha.com. The good thing about the Ox66 is that they run pretty good even when things are off a bit. Get the fuel system tip top, they run like new.
