2006 496mag 3500rpm beep beep Why
 

at 3500 rpm beep beep,and the rev limiter kicks in,oil press 65psi,water temp 160,help

Had it happen to a friend with 525's. He had a bad neutral safety switch adjustment, computer thought it was in neutral and kicked in the rev limit. You can check it with a scanner or the Rinda program. BTW, it will not set a code.

You may have a Exhaust manifold overheat conditon due to water flow. Especially if you have an aftermarket exhaust manifolds.. If you do, mostlikely The water flow is not balanced.. Also you didnt say if this happens in neutral or in gear. If it is in neutral it is just keeping you from over revving the engine.. ;)

In either event without having it scanned & monitored they are all just guesses... ;)

problem solved,must be in gear,neutral only goes to 3500 rpm

why are you revving the motor in neutral? there should be no reason to do this.
