Tony I'm having electrical issues with my 91 also. Have narrowed it to a ground I think. Boat has a lot of corroded wiring. I'm having to do some rewiring. Can you take a picture of you dash panel/switches? None of my switches have labels. So far I've got my manual bilge, blower and lights working. Have two other switches that I do not know what they go to...sorry for the thread high jack.
