Susan, what year is your Centurion Elite. I think the hull on an 06 Elite is the same as an 06 Lightning. Thereís also an Elite bow rider, to be honest I canít keep all the models straight.
I have an 04 Lightning which has the same hull as some version of the Elite. My hull is a ski boat hull with spray pockets and a hull extension. If you have a boat like mine I can give you some good setup advice.
When I setup for regular surf on the port side of the boat I set the trim tab up. On the starboard-goofy side I set the trim tab down. Also on the starboard-goofy side surfing you might actually consider filling the port ballast tank part or all the way. Depending on the weight we had in the boat we ran either 100% or 50% trim down when surfing on the starboard side. This year with significantly more ballast we run the trim tab all the way down.
Iíve modified my ballast system quite a bit this season so the rest of my setup probably doesnít apply to your boat. However I did quite a bit of surfing last year with the stock setup. On my boat getting a strong list (lean) is really important for making a good wake.
If you have a newer 06 hull youíll probably make a good surfing wake with less effort than on my 04 Lightning hull. Good luck and letís see some wake and surfing pictures as you begin to figure it out.
