I'm not debating...trying to be humourous....Starting to sound like the small block / big block debate from the 70's. Small block would beat me to 1/2 track and then I'd walk right by before the finish line... They could never catch me on the highway.
Does a couple seconds on take off change the course of the days fishing? or do the low transom bas boats as you say need the 2 stroke because the 4 strokes weight would sink them? Top end HP for HP isn't going to change anything whether 2 stroke or 4 stroke other than the minor drag added by the engine weight. Almost impossible to test unless you swap motors out on the exact same boat/duplicate fuel load and gear being carried.
