Tach reading too high on '96 Johnson 115

[JJags3]

When the motor is cranked, the tach seems to be reading about 2 times what it should, i.e., 2,000 when it should be 1,000 and continues that way right on up to full throttle. Any suggestions on what could be wrong? It just started doing that.
Thanks

What brand tach is it? Did it just start doing this?

If this is for a 115, the setting should be 6P. Bookmark this link for future reference and see page 4:
