I haven't seen any boats down there running turbines. There are a few of them in northern Alberta, and do they ever have power. The more research I do on the this, the more it makes sense. It is the way to go in order to have 1000+ continuous power that doesn't blow up. When they first started showing up in the unlimited class jet boats, (which had been dominated by big cubic inch reciprocating engines) they immediately dominated. Not that they were necessarily faster (although most were), they were reliable, meaning they didn't break down. Ultimately, they are proving to be less costly than exotic big block engines. These are take outs out of helicopters, which are no longer airworthy, however they still have many hours of life left in them. I think the next engine I buy is going to be General Electric rather than Ford or Chev. To me, burning jet fuel just has the smell of power.
