CAUTION: Never attempt to retrieve a downed boat
by swimming. If you need to retrieve your boat from
the water, use fishing equipment or another boat.
NOTICE: When running at full speed in choppy water, the
propeller may exit and re-enter the water repeatedly and
very quickly, subjecting the propeller and drive shaft to
some stress. Frequent stress may damage the propeller
and drive shaft.
In rough water and windy conditions, consider:
• mounting the batteries further forward for added
stability
• adjusting the struts downward to prevent the boat
from overturning
Strut Angle Adjustment
Your boat's propeller struts have been factory adjusted
for a neutral ride attitude. This setup works well with the
recommended battery packs, in calm to light chop, with
wind blowing at less than 5–7 mph. The struts are adjusted
at a neutral position, 0 degree angle, measured with a
ruler, which places the struts parallel to the bottom of the
hull. This adjustment allows for the best use of the boat at
maximum speed.
Use two metric rulers to adjust the struts; one must be at
least 304.8mm.
WARNING: Never attempt to adjust the propeller
struts with the propellers installed or while the boat
is powered on. Servere bodily harm can occur.
1. Remove the batteries and ensure the boat is powered
off.
2. Use a 2.5mm hex wrench and a 5.5mm nut driver or
open-end wrench to loosen the stainless steel bolt that
holds the strut's angle.
3. Remove the propeller for the strut that needs
adjustment.
4. Place one ruler across the bottom of both of the rear
ride pads. Ensure that the ruler extends from the middle
ride pad to the end of the strut propeller that needs
adjustment.
5. Place the second ruler across the first ruler, forming a 90
degree angle against the propeller strut.
6. Measure the distance between the bottom ruler and the
propeller strut, at the propeller strut's farthest point.

Avoid boating near:
7. Make strut adjustments in intervals of 0.5mm to 1mm.
Record the first strut adjustment and repeat the process
on the second strut. The boat is sensitive to strut angle
adjustment.
NOTICE: Do not adjust strut angles greater than 4
degrees positively (up) or negatively (down). If the boat
requires more than 4 degrees of adjustment to run well,
check the battery placement and ensure that both struts
are even.
8. Once the first strut is adjusted, carefully tighten the
2.5mm screw and 3mm nut that hold the strut's angle.
Double check the measurement to verify the strut
has not moved. If the measurement has not changed,
tighten the screw completely.
9. Repeat this process on the second strut. Once both
struts are adjusted, repeat processes 4-6 on both struts
to ensure that the struts are even.
10. Once you have made adjustments, your boat is in the
water and you are ready to test your adjustments, get
your boat on plane and ease in to full throttle slowly,
watching for erratic behavior. Your boat should run
mostly on the last 2 ride pads, bouncing slightly as
it passes over its own wake or cuts through chop. It
should not be lifting the nose and slapping the water
while running at full speed.
Tip: Keep a log of the strut adjustments, water conditions,
and battery weight/sizes that may have required strut
adjustment.
