    OX66 O2 sensors and winterization

    Should the O2 sensor be cleaned after fogging the engine for winterization? Will the oil contaminate the sensor and shorten the life if not cleaned?

    Stuck on the ramp

    I have 2 of these outboards and this weekend I cleaned both sensors using the methods described in this forum. Although I didn't have a test harness, I soldered 2 test wires on each O2 sensor so I could read the voltage (across the black and grey wires). Once warming up they both settled in...
