Evinrude Tacho gauge

The Gauge for my evinrude is on 3300 RPM before I start the engine ?, is there anyway to reset it too Zero ?
All the warning lights work when you switch on the ignition, its just seems to be the tacho out of sync ??
Thanks

its connected to a E50PL4ss outboard

Does it go back to zero when you turn the ignition to the on position ?

No, its stays at that point !

Stick a meter on the back and check it has power

Oops, just re-read your post, and it obviously has power, so I'd plump for a duff gauge!

There is a small screw accessible from the back.
It is NOT a zero adjust screw, so don't try that. Been there, done that.
I think it adjusts somewhere in the middle of the range. I can't remember exactly.

The armature on the needle has seized. Had this on an old Honda gauge not a lot you can do unfortunately.

Strategically placed drop or two of penetrating oil, perhaps?

Thanks for all your replies

I had sort of gathered this but needed to be assured by the rest of you that it was beyond hope !

Sorry, cant see the link but might be worth a peruse for other ideas ( & maybe a second hand rev gauge !)

Thanks

I concur with what has already been said - the armature is stuck, probably due to moisture in the gauge corroding it.
If you're patient/careful, you can 'un-crimp' the metal bezel from the body of the gauge by carefully and progressively levering it apart with a flat bladed screwdriver. The needle can then be freed off (they are free to rotate 360 degrees in these gauges). Drop a pack of silica gel in there while you've got it open. I use a miniature bench vice (with plain jaws) to then re-crimp it all back together.
Or you could just fork out for another one!

It seems to be a bit of a design flaw that the gauge body is not a sealed unit leading to moisture ingress.
