Well thats where it gets a lot of its speed... the hull only weighs about 950lbs... but in retrospect (i hope thats the right word), most of your run of the mill 20-24ft I/O boats are between 200-250hp and are running 45-50mph.. this 21ft boat is running 80+ on 50 less hp... I guess what im getting at, for its size, in comparrison to all the other small sport boats, even little jet boats that the PWC manufacturese are making... thats a small engine.
