Hi gang, new to us 91 ski centurion tru trac 3. Sorting it out mechanically and getting a porposing developing when accelerating at approx 3/4 throttle. Can I drive through or out of it? Gassing it doesn’t break the porposing, only slowing then accelerating slowly. Any advice appreciated. Boat is near full fuel, not loaded abnormally. Thanks
