Hey guys,

interesting issue popped up this weekend. I was taking a hot pass, had the stick to the floor, and the boat trimmed great. 77mph on the gps speedo, what a riot! Then my buzzer goes off (constant). Gauges are all fine, aside from the high water pressure (imco shorty). I pull the stick back, and it stops sounding. But then every minute or so, it beeps twice...

Now, it runs super rich and seems to be missing at low rpm. Then cleans out when you get on it.

Any ideas??? Has anybody installed a smartcraft SC1000 system monitor? That would help get any codes...

Aside from the imco shorty, the only other thing I have done is replace the corsa tips with hardin marine tips with flappers.

Help? :)

Tom

Only way to really know is to hook it up to a computer and check for any codes.....could be many things causing the beeps......be there done that..:shades:
