   Hi Mike,

   Bob Darrah and Russ Kotlarek are both going with a 20B. I believe we
   have
   another person on this discussion group here with the first name
   Marc. who
   is also going that route. Russ just ordered parts to do an all new
   aluminum
   housing (except for the wide intermediate housing) engine with
   Iannetti $$
   ceramic seals. I personally want to go with an all aluminum two rotor,
   whether that means a very enhanced 13B P-port or the new generation
   16X due
   out in a few years. There are lots of issues to consider, but one thing
   going in our favor is that by losing engine weight we can move the
   battery
   back from the nose and lose another 50lbs in heavy wiring cables. I
   believe
   the SeaWind on a strict diet could easily lose 250lbs and that means it
   doesn't need as much hp. The only time a seaplane really could use the
   extra muscle is for those few seconds on water takeoffs to break
   free of the
   water suction. The design started out flying with 200Hp. Then 250Hp was
   considered ideal as the plane became more reinforced. Now 300Hp is
   standard
   and TIO-540s, and turbines are flying and the design became a IMHO a
   little
   piggy. Like many home builts, the design suffers from Hp creep.


   Regards

   If anyone is interested, I found some info on the rotex
   Supercharger.  Apparently the BM'ers (sp? But I guess if you can't
   afford one, you don't need to know how the spell it)  use them.  The
   chatter on the web is that they also now want more power.  May be
   some used ones coming up.  Also saw this ad:

   "We currently have out c-30 kit on sale. Regular price is $6500.00,
   its on sale now for $3995.00.
