Hi new here I have a question on my 05 turbo aquatrax when it got around 61 hrs on it I noticed at WOT it would drop and raise a few hundred rpm it doesnt do it all the time.What is really odd my friend has a 04 like mine and his started doing it at 50hrs.2 dealerships failed to duplicate and repair it.A lady a lot over at the lake claims her like ski has done it too.thanks for any ideas........Gary
