Greetings,

I would like to know what opinions there are about whether to use a 2 or 4 stroke in a sport ship I built from plans. It is called a fantasy and I have never seen it before, can't find anything on the web either. I would say it is a large 40 to 60 size but has a small engine bay. I love the sound of the 4 strokes but am unsure of what size 4 stroke would get the job done in a small space. It currently has a magnum 40 in it, little tight on the fit, and on the maiden flight the instructor said it felt under powered, so I am looking at the .52 size engines; 4 and 2 stroke. Any ideas?
