    Yamaha Fuel Management System

    The fuel management system on my Yamaha F225 outboard is currently not working. No matter what speed I am going, the fuel consumption reads 0.0 gph, and the totalizer is stuck at 68 gallons. I have used at least 20 gallons since this figure has moved. Note that the guage still displays numbers.

    Is this indicative of a stuck/clogged sensor? Or is it likely a wiring problem? Any sugestions will be greatly appreciated.

    Thanks,

    Paul

    I took out the sensor and blew some air through it. I could see some crud blow out of the unit. I hooked it back up and it's working.

    I cureently have a fuel/water seperating filter upstream from the sensor. Could the crud be caused by ethanol? What can/should I do about it?

    I really did not get a good look at the crud, as it flew out into the wind, but it looked whitish. I was thinking it was teflon tape, either the regular or liquid kind.

    I did not install the unit initially. I looked more like a dry powder. Perhaps something along the lines of a sealer, rather than tape.
