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.
