I'd like to see any numbers too.....I'm down to two choices for my bracketed Tsunami....twin zuke 140s or twin 175 optis (performance wise this one wins....
The 175 Optis weigh in at 431lbs and the zukes 420lbs. The zuke is less $$$ and is a 4 stroke. The Optis have power to spare and smartcraft. The 115hp optis could be an option, but I think that could be a little under powered....but they only weigh 370lbs, are cheaper and have smartcraft too.
