Listen to Justaddwata, he knows what he is talking about. The Magnum 57 would never handle those kind of speeds and you would over power the hull, and yes, it would take an "Act Of God"
I went 73.6 in testing here with this boat and set a new record a few weekends ago at 70.8 mph up in Flint Michigan. The old record was 64.8 mph with a J&G Motor in a Seaducer.
