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
Adjusting the Trim Angle
The outdrive struts on the Villain 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. As the outdrive is trimmed up, the bow (front)
of the boat will ride higher. The Villain 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 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.
TRIM UP
TRIM DOWN
Loosen nut and steering
rods to adjust trim. Use
a 1.5mm hex wrench to
loosen the steering rods.
