I have a 250 Etec on my Tsunami with a Hermco bracket. The boat also has a hard top/enclosure which adds weight and windage. Aside from being the best starting and smoothest motor I've ever run, it's strong - pushes the boat 45-50 mph depending upon load. The prop is a 19" pitch Viper. No maintnence of any kind needed at 2 years. In my subjective opinion, it is louder than a 4 stroke at planing speeds.
