RE: Seamaster perfect engine??
I'm definitely not a wring it out kind of guy and as long as it's adequate I'm good. Heck I fly a H9 80" span cub on wood floats with a Saito 56 and it's great. Takes a little skill to get it off the water but isn't that part of it, learning the skill? Once it's in the air it has more than enough power. That's nice looking plane by the way.
