2008 Optimax Pro Xs 250 Beeps
l have a 2008 Mercury Pro xs 250 on my Z520 and I have been having a problem with continuous beeps. Oil container in the boat and under the cover is full. Have already tried bleeding the oil container under motor cover. Also checked the float and sensor. All good. Boat cranks perfect, beeps start sounding with Warning bell and motor symbol showing. Engine idles rough and will not plain off. At first it would alarm and if I shut it off the alarms would go away and all power was there. Now alarm comes on time I crank it and will not go off. Boat has new computer but also done it with old computer at times. In last two years I have had a new compressor and fuel rails changed by dealer. Any suggestions would be greatly appreciated.
