Propeller Service

1. Use an 8mm nut driver (DYN2805) to loosen the
nut from the driveshaft. To secure the propeller
while loosening the nut, hold the propeller.
2. Remove the nut and propeller from the driveshaft.
3. Assemble in reverse order. Correctly align the
propeller with the drive dog on the driveshaft.

Propeller Strut Depth Adjustment

Raising the propeller strut increases speed but decreases
handling.
Lowering the propeller strut increases stability but
decreases speed.
1. Use a 3 mm hex driver and 7mm open-end wrench
to loosen the propeller strut bolt.
2. Slide the strut up or down to change the angle of the
propeller in relation to the hull.
3. Once desired strut depth is achieved, tighten the
nuts and bolts.
