I have the exact same boat and I love it!! It rides great and is very stable at 70(as fast I can go at this time). I dont see why you couldnt get 100mph out of that boat with out being safe. Mine had a 800hp engine in it before I bought it and he was in the lower to mid 90's with it. I also like that it has two 22 gal tanks, can play for a long time without having to refuel.
