I wired up a tach to my boat and the rpms are off. I know this is based upon the pulses it gets from the flywheel but can't seem to visually identify how many magnets are in it. Does anyone know how I can determine the proper setting (or know what the proper setting is?). I can probably get close by the sound of the engine at idle and guessing the rpm but would like to be sure.
