     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

     Doug

     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.

Mike,  I have a 20B I was going to put into an
aircraft until medical problems arose.  I have since
bought another and had both of them configured for
marine use by
Atkins Rotary in Puyallup WA.  They put one of them on
a dyno and it pulled 275HP normally aspirated with raw
intake (no special intake pipes.)  The boat I am
building is a thirty foot inboard driven by twin
Berkeley Jet pumps. I'll let you know how it works
out.  The engines will be mounted in about a month and
the boat will be launched this spring.  I hope it
floats!!  There are superchargers available to raise
my HP to well over 300, and I am seriously considering
going that route.
