i have the 23ft buttcat sportsfisher(cabin) version.
i run 2 x 70hp suzuki 4strokes and it runs great. i am from cape town so dont surf launch but often run to the deep. i find the motors enough for my applications. my suzukis are the older being 2008 models which weigh about 157kgs. the new yamaha 70's are about 30kgs lighter if i am not mistaken. not sure about the suzukis.
hope that helps.
