Propeller Thrust Angle Adjustment Tips

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 Blade-X 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: For the twin set up Blade-X, the amount of degrees on the thrust angle you adjust,
must be identical on both drives.
