96 Mercury 200hp

This is on a '96 Mercury 200hp EFI outboard S/N og373964. I have been experimenting and found that if I disconnect the one purple wire feeding the low oil warning control the beeping stops. According to the print out from Mercury this control box is just for the low oil alarm. Does anyone know anything about this? I just want to disable the alarm to run premix and see if the oil injector system is still functional and not just a sensor gone bad. I want to make sure this does not disable the temperature warning too.

Re: 96 Mercury 200hp

it won't disable the overheat but it is either the sensor that has gone bad, or the float in the oil tank is saturated and has gotten to heavy. Make sure the motor tank is full of oil to the very top. The oil tank on the motor never refills itself full if you have everlet it go low and not let it fill with the cap off. Check the motion of the float. On the models with the tank on the front of the motor it is on the cap. Moving it to the top of the cap should shut the alarm off. On the side mounted tank stick your finger in the tank to the rear and slide the float up and it should shut the alarm off. Make sure the oil warning you are getting is 4 beeps evry 2 minutes and not a really fast beep. a fast beep is your oil pump motion sensor. If so you may have a major problem. Make sure you are getting oil to the motor oil tank by running the motor with the oil cap off. It shouold fill up to the top where you want ti. start from there.
