I went with a 917 on the bow of P3 a couple months ago. I love it. Great unit for the money. From what I understand, SI doesnt work well up front. The 917 has got everything you need up there, plenty of power,a big brilliant screen, and there really isnt a need for navonics up there. Now Im waiting to pull the trigger on a 997SI for the console and network the two for exactly the reasons Basschaser mentioned. Id save some money, go with the the 917 and network it to that plasma TV you have on the console. You wont be sorry.1999 Pantera III 1999 200 Opti 25P Tempest Minn Kota Maxxum 70 2 Pinpoint 7520s
