I have a 2004 Speedster 200, and the tachometers are not at zero, even with the battery disconnected. Is there any kind of adjustment for this? One reads about 1000 RPM, and the other is at 3000RPM. When the engines are running, the do go up, but aren't accurate.

The tachs haven't been submerged, and the boat has been covered when not in use. First the tach on the right wouldn't zero, then the one on the left a couple of weeks later.

still sounds like moisture
they are sealed in front but not completely
you can spray some sylicone lube through the hole in the back used for lighting the guage but it will get on the face and not look nice any more ,
It can be taken appart but it is like taking apart a watch , you up to that?
Ive done it but would not reccomend it ,
guages are cheep. try the spray then shake to brake loose the jewls
They wont return to zero because at zero is where the tension from the ckock like return spring goes to zero , so the place that the guages are resting now is where the resistance to the spring excedes the tension from the spring .
Lubricating it then shaking it back and forth will soolten it up enough to allow it to return to zero
The only other thing that could be wrong is if the guage has ever received voltage in excess of its safe working limits. This can be caused by a faulty voltage regulator or through improper jump starting but the why does not really matter
the indicator gear can slip on the semiring gear due to going past its limits ( It just over runs the track as it were) Then it is more than an adjustment , If it were reading 500 instead of zero I could adjust it . If you lived close to me I would do it for you on a weekend but it sounds like a gear over run when it is off by 3000RPM
Thanks for the very helpful information. My next step will be to try to take one of them apart, and see if I can lube and repair. If not, I'll just replace it!
