Sounds like an electrical short or loose connection somewhere. One of our electrical gurus will probably have the answer.

I've started the engine before and found that none of the guages were working. Jiggled the key and they came on. Could be the contacts on the key switch are getting burned and will require a replacement someday (when jiggling the key doesn't work anymore) Jiggle your key to see if it takes the flakiness out of your tach.

Mike and Ray have good advice. Please note that the tach works off a signal from the alternator, so you should check the wiring not only at the key switch and behind the engine control panel, but also at the alternator. About a year ago I was doing a regular "watch the engine" inspection when I noticed sparks coming from behind the alternator. One of the ring terminals had gotten loose and was arching across to the diode. Not fun, but I caught it and checked all the other terminal, including the starter and engine grounds.

Rich, it just occurred to me, that if you haven't read the following, it might be worth your while. Good input for a new boat owner:
