Author	Topic:   Tach - Adjust or Replace?
newt	posted 08-12-2003 08:30 AM ET (US)         My Mercury tachometer reads 800 rpm with the motor off. While underway, the tach appears to work fine, but I have no way of knowing if it is indicating the correct RPM's or 800 RPM's low. Is there a way to adjust the needle, or is the tach junk?
