The adjustable strut didn't keep its intended position due to the excessive engine torque, so an additional brace was attached between the strut and the rudder support to fix it in place.

Yes this is it.


Update 05-12-2007.

Bad news. after a fly over and touched the bottom of the lake, the boat was damaged.
So time to repair the hull and paint it all over.
First i had to fill allmost 500 holes who where arise true the crash, and sand down some
places on the gel-coat.
Putty and other stuff cam handy.
And after a lot of time, this is how she looks now.
