In THAT case, I would think you could build a solid, reliable BBF or BBC, have it installed in your Tahiti, convert it to a Berk, if it's a Jacuzzi, and have said Berk (If it already has one GREAT!), solidly built for far less money than a Seadoo or Yamahammer would cost. Less, and easier maintenance as well, but that's just me.
