I have twin fuel injection 40's on my boat, and the alarm goes off one one of them after about a minutes running, except at 5000 + rpm when its not an issue. put the computer on it and was told it was the oxygen sensor, swapped the sensors over between engines and sure enough the problem moved over to the other engine. Anyone any ideas as to why? The expensive honda mechanic with his computer told me the part number for a sensor was 35655-225-004 but no suppliers on the net seem to recognise this code. Can I unplug the sensor and run the engine safely like that, as the alarm continually sounding off is driving me to the point of damaging something.
