Thanks...but in the manual it shows how to reset a code if you know the existing code. I discovered a fix that requires unplugging the 8-pin connector under the dash and entering a code. It does not work on my boat. I also heard that you may be able to unplug the battery for a day or so in an effort to run down the internal battery on the security system?Yes, there is the procedure in the repair service manual. I can get you directions tomorrow night if you don't find them. Do a search since i posted something on this before.
