Release the M4 hex nuts on both side of the top support bracket, you will be able the move the
complete drive up and down for the thrust angle adjustment, Angling the prop up will lift the front
of your boat, generally resulting in less hull in the water and faster speed. Angling the prop too high
though will cause instability and the prop may "ventilate" or spin without gripping because it's too
close to the surface.

Angling the prop down will lift the back of the boat and keep more hull in the water generally
giving more stable running but with less speed.

Trying different prop angles will find the one that works best for your boat in different water
conditions. To start with, set the surface drive at straight angle see how the boat runs, then
according to its performance, you can try to adjust the thrust angle up or down at just one or two
degree a time to see what effect it has, and try again until it reaches the performance result of your
satisfication.
Note: The amount of degrees on the thrust angle you adjust, must be identical on both drives.
