A couple weeks ago this part failed. Mercury 8M0021043 Fuel And Water Sensor.
Replaced it went out ran good for the day. Went out again and at low idle (5mph zone) alarm went off, long time pause in between and motor icon on smart gauge. Shut down restarted and did not sound again. Went fishing for a few hours 3 or 4 long runs no issues. Got back to the 5 mph zone and I could feel a slight surge in RPM at slight throttle, alarm went off again. Loaded up and went home. It's about a month before I can get an appointment. Anything I can look at?
When the sensor blew out of the tank shooting fuel out of the hole, we did run it in at light throttle for a mile or so.
