Propeller Angle Adjustment, continued
6. Position a ruler along the keel of the boat so that it extends
past the boat's transom. Adjust the prop angle.
7. Position a second ruler across the first ruler, forming a 90°
angle against the propeller strut.
8. Measure and record the distance between the second
ruler and the propeller strut, at the propeller strut's furthest
point from the hull.
9. Retighten the strut bolt.
Tip: Keep a log of the strut adjustments, water conditions,
and battery weight/sizes that may have required strut
adjustment.

Propeller Service

1. Use an 8mm nut driver to loosen the nut (A) from the
driveshaft (B).
2. Remove the nut and propeller (C) from the driveshaft.
3. Inspect the propeller for any damage or wear and replace
as necessary.
4. Assemble in reverse order. Correctly align the propeller
with the drive dog on the driveshaft.

Trim Tab Adjustment

The trim tabs come installed from the factory to stabilize the
boat as it rides across the water. They are set for consistent
performance and stability in most water conditions. However,
you can tune out chime walk or porpoise effect by adjusting
the trim tabs so they are at least 1–1.5 mm below the ride
surface of the boat.
Adjusting the tabs up or down allows the boat to come in
more or less contact with the water, resulting in either a
smooth, planted ride or a fast, loose ride.
1. Position a ruler parallel to the keel on the right side of the
right trim tab, allowing the ruler to extend past the trim tab.
2. To adjust the angle of the trim tab, carefully bend the
tab past the ruler. Use a second ruler or depth gauge to
measure how much you have bent the tab past the first
ruler.

3. Use a ruler to measure and record the tab bend.
4. Record the position of the trim tab against the ruler's
straight edge after adjusting the trim tab.
5. Repeat this process on the left trim tab, ensuring the trim
tab panels are either perpendicular to or parallel to the
bottom of the boat.
NOTICE: The trim tabs should be the same distance above
or below the boat's ride surface. Adjusting one trim tab more
than the other can cause the boat to behave erratically.
NOTICE: If the boat rolls or flips at full speed, the trim tabs
or turn fins may have moved or flexed. Immediately return
the boat to shore for inspection.
