Ok so first time I really got to ride my new ski I gps at 65 every time a couple times got 66 mph is this the top speed ?or can I get a little more out of it? This was on last years gas I guess I'm just wondering if my ski is as fast as it should be . It's defiantly a rocket the only thing I noticed was a big gouge in the ride plate from a rock .also, should ride plate be caulked around the edge also ?
