What would it cost if you built a ski boat with an interior comparable to a 1999 Ski Nautique(no Sea Deck), modern running surface, analog gauges, traditional source unit for a stereo, a 350-400HP engine, keyed ignition, traditional control switches, and Zero Off. The only touch screen would be for the zero off only. I am thinking a basic traditional closed bow boat with a modern running surface. I am guessing a boat 19'6' to 20'.
