As far as how much, 17k. The problem I faced was there are virtually none of these boats in Northern California and very few in California. Over the past four or so years I only know 3 late model boats that came up for sale in California and none were close to me. As far a cavitation, thats really what has stopped me from completing a 360 - but I'll figure it out! And I have a gopro setup in case the wife ends up in the drink ;-)
