http://www.evinrude.com and watch the clip regarding bow rise with 4 strokes vs e-tecs. i think it will answer your question
on a personal note i bought an 01 logic 186 which is todays 190cc and had a 115 yami 4s on it. i could never get it to drain deck water due to the heaver 4s engine and trim was an issue as well. it i had a do over i would have used etecs on that one as well as the 01 210cc i currently own
dunno---maybe i have watched that 1/2 hour e-tec infomercial too many times on verses waiting for the next fishing program!!!!!
