Seven Marine vs Verado
#31
But it illustrates the point of why the Seven Marine motors we developed.
Comparable power/performance with less infrastructure.
Sometimes 20% less.
Sometimes 33% less.

Well, I imagine the culprit of that might be a wide-beam boat doing high speed turns that leans enough to pull the outside props out of the water. Bouncing off the limiters on re-entry it fatigues/shears the shaft. Looks like the props are run fairly high as well exacerbating the issue.

Not sure if you all remember but Nortech ran a 390 w triple 557's some time ago. Boat ran 88mph or so. At the time everyone was stoked. Now price out 3 motors at 60k each. 180k.
Nortech builds a 390 with quad 400's. Similar hp. Motors around 30k each. 120k total.
Seems like easy decision for me. By the way boat ran 100mph.
I have seatrialed many Intrepid's with 7 power. They are also louder than the 400r also. However there seems to be the cool factor of owing a boat with them as not everybody has them.

Also, did the Triple 557 boat have the T-Top on it for those speeds?
The Quad 400 boat did not have T-Top when it they set that speed record.
