My 2002 Supreme V Pro Sky has the Mercury Marine SmartCraft 5000 system installed (<a href="http://www.mercurymarine.com/smartcraft" target="_blank">http://www.mercurymarine.com/smartcraft</a>) and I'm curious as to what this might have added to the base price of the boat. <BR> <BR>Does anyone know what this system sells for as an aftermarket add on or as an OEM option?
