Hold a ruler against the
hull. An imaginary line
from the bottom of the
hull should intersect the
center of the prop. This
is the default setting.

Adjusting Your Villain EX
Adjusting the Trim Angle
The outdrive struts on the Villain EX will allow you to adjust the
trim angle of the propeller. The trim angle changes how high
the bow of the boat rides out of the water. Setting the trim
angle correctly will provide the maximum speed and efficiency
from the Villain EX. As the outdrive is trimmed up, the bow
(front) of the boat will ride higher. The Villain EX will run slightly
faster however, it will be more unstable in the wind. Do not trim
the outdrive up on windy days or when running in choppy
water. If the trim is set to high, then the bow will bounce up and
down (“porpoise”), and the prop may begin to cavitate.
As the outdrive is trimmed down, the bow of the boat is
lowered thus increasing the wetted surface of the boat. This will
slow the Villain EX slightly but, stability and control will be
improved. Experiment with this adjustment to find out what
works best for your particular conditions. Make sure the trim
angle on both outdrives is set the same.
Adjusting the Outdrive Shaft End Play
There should be a slight amount of shaft end play in each
outdrive housing. To adjust the end play loosen the grubscrew
on the u-joint yoke (see drawing). Pull the propeller shaft until
there is no more than 1mm of distance at arrow 2 in the
drawing. Retighten the grub screw. This setting would not
normally require adjustments unless repairs have been made,
or the props have been replaced with aftermarket props.
