Prop selection may be difficult as well and you may need to speak to a specialist like Propeller Revolutions in Poole as I've meard many mutterings that Evinrude props leave much to be desired.
I know several people who are or racing or drive their rib very hard with E-Tec's. 2 out of 5 had problems with the saddle. But my gut feeling is this would also have happened with a yamaha or regular optimax engine as they are being driven really hard. The other people I know with an E-Tec and who drive it the "normal" way, had so far no problems.
As far as the props go, I heard nothing but good things about those in terms of performance and acceleration. It was with the evinrude prop we reached the best top performances (we tested more or less 7 different props). The only weak part of the props is the rubber ring inside the prop. When the engine is mounted very high or on a hydraulic lift, and you go flat out for a long time, there is a risk that the rubber ring heats up too much... (but this is often in extreme conditions).
