Mercury Tachometer
Posted: Tue Aug 28, 2018 12:28 am
The tachometer on a Mercury OptiMax 135 just started acting up. At times at idle [the Mercury tachometer will read] 4000-RPM, and then will settle down to 900-RPM. At times you can tap on the tachometer, and [the reading will return] to normal.
[Is the remedy to this problem to discard the tachometer and replace with] a new one?
Thanks for any help.
