I've been putting together a Phoenix SeaBee and in the instructions it shows a right thrust of 2 degrees and zero up/down thrust. However, the firewall measures 3.85 degrees right thrust and 1.10 degrees down thrust.

Does anyone have suggestions as to the best engine thrust angle from actual flying experience with this model? I could use Ernst engine shims to set the thrust angle according to the instructions if the SeaBee flies well using those numbers. Has anyone else noticed their SeaBee's firewall thrust angle is not according to the instructions? Thanks.
