Hi all I have a question regar

Hi all I have a question regarding adding an hour/tach meter to a 9.8 tohatsu motor. During setting up the hour meter I need to select the spark revolution for the meter. So does the spark fire twice per revolution or once per revolution or once ever revolution? I would like to get this right so I will keep accurate hour information for the motor.
Thanks for the help Bill
 
Most of these tachs will not w

Most of these tachs will not work. I would call Tohatsu at 972-323-6003 and see what they say.
 
Thank you for the information.

Thank you for the information. I called them and they seam to think it will work. As far as firing per revelation they said it fires on every revelation.
