Re: 500efi troubles
I have a pair if 1999 500hp's (carb). The alarms go off after a hard run, then quiet after a couple minutes at idle. Both engines do it. All gauges show normal, and drive bottles are full. I'm stumped! I unplugged the drive bottles....didn't help.
What now???
Help?

i'm not a mechanic, so hopefully my "non-techie" comments were understood.

if not, unplut each of the three sensors to narrow the scope of your problem. i'd bet your senders or connection(s) to senders are bad.
