Propeller Service
1. Use an 5.5mm nut driver to loosen the nut (A) from the
propeller shaft (B).
2. Remove the nut and propeller (C) from the flex shaft.
3. Assemble in reverse order. Correctly align the propeller
with the drive dog on the flex shaft.
1. Place a ruler on top of the strut to measure the distance
between the aluminum swivel mount and the composite
rudder.
2. Use a 2mm hex driver to loosen the top screws (2)
that hold the composite rudder to the aluminum swivel
mount. Only ½ turn is necessary to loosen the bolts.
3. Use a 2mm hex driver to loosen the bottom screws (2)
that hold the composite rudder to the aluminum swivel
mount. Only 1/8 turn is necessary to loosen the bolts.
Tip: Loosening the bottom bolts too much will make
adjustment difficult. Slight friction is needed to hold the
adjustment.
Lowering the Strut will lower the bow, increasing the
boat’s contact with the water. Use this setting for rough
water and/or strong winds. This setting increases steering
input.
Raising the Strut lifts the bow, decreasing the boat’s
contact with the water. Use this setting for calm wind and
water conditions. This setting increases speed and bounce.
Applying throttle during a turn in this setting makes turning
difficult.
1. Carefully disconnect the water lines from the motor
cooling sleeve. Rotate the cooling line back and forth,
while pulling away, to loosen it.
2. Disconnect the motor wires from the ESC.
3. Disconnect the servo lead from the receiver.
4. Use a 2.5mm driver to loosen the bolt that attaches the
motor to the motor mount and remove the motor.
Tip: Loosen the screw 1–1¼ turns but do not
completely remove the screw.
5. Use a 2mm hex driver and loosen the set screw on the
motor coupler.
6. Remove the motor.
7. Use a 1.5mm hex driver to loosen the set screws,
holding the servo steering links to the swivel barrels
mounted to the composite push-pull lever.
8. Use a 2mm hex driver to remove the screws that hold
the servo mount to the aluminum motor mount.
9. Move the rudder to the left and then right to remove the
steering links from the swivel barrels.
10. Remove the servo away from aluminum mount.
11. Use a 2mm hex wrench to loosen the bolts holding the
servo to the composite servo mount. Service the servo
as needed.
