ITEM: Yamaha HPDI 200hp Outboard ECU (Engine Control Unit). (Part #60F-8591A-20-00 supercedes thru 60F-8591A-23-00). This CDI is guaranteed to function properly. No corrosion on the connector pins (see close-up pictures). To the best of my memory it had approx. 375hp on it when we ran the diagnostics.
