Outboard Tachometer Applications Notes: a. 6000 RPM tachs are for Inboard & I/O gas engine applications only b. 7000 RPM & 8000 RPM tachs are for all outboard motor applications … … Pole Tachs are no longer available. c. Electrical pulses per revolution are equal to 1/2 the number of alternator poles. d. Older model outboards (prior to 1977) may have the tach signal wire originating at the ignition system though they are alternator equipped. All alternator tachometers may be used on these systems by disconnecting the…
