mine was a almost no hour demo boat so it was ready tight away and the 90/65 etec pushes it great. with three guys in it it jumps up on plane right away and cruises at a nice speed. havent had 4 guys in it yet but it didnt feel underpowered at all with three and a dog. uses way less gas than my old 18' supervee with a 115/80 from 1993. it even was fishy is first trip out.
