I have a 1996 Polaris SL780. It works just fine when I am the only one riding the ski. The problem arises when my wife and I want to both ride it. When we both ride it the ski tends to want to buck up and down like I am hitting another boat's wake when I might be in calm waters. I suspect it is a trim issue. I have messed with the auto trim and I know it it working. It does help out a little bit if I can find the sweet spot on the trim and it won't buck as much. It still will though and then I have to steer a little from side to side to help it so that we don't get completely jarred on the ride. Any insight into what might be causing this issue would be much appreciated.

Thanks

Called "porpoising" and it's a common issue. FIll the fuel tank up, trim all the way down. Look around for aftermarket ride plates that will help. Could modify the ride plate by adding a couple inches of plate onto the back of it.
