tear. Use Dynamite Precision Oiler: Medium (DYNE0100)
to lubricate the bearing. Use new bearings and seals
(PRB286053) if the bearing or O-ring needs to be
replaced. Use Dynamite Marine Grease (DYNE4200) to
lubricate the O-ring.

Rudder Assembly Removal
1. Use a 5.5mm nut driver to loosen the propeller nut from
the propeller shaft.
2. Carefully remove the propeller from the propeller shaft.
3. Use a 2mm hex driver and loosen the set screw on the
motor coupler.
4. Carefully remove the flex shaft from the boat.
Tip: If the flex shaft is difficult to remove, use small
tongue-and-groove pliers (multi-grip) to hold the motor
coupling while rotating the shaft clockwise as you
remove the shaft from the boat.
NOTICE: Rotating the shaft counter clockwise inside of
the motor coupler will damage the flex shaft, requiring
flex shaft replacement.
Tip: The outer bearing and composite spacer can
dislodge from the rudder housing when removing the
flex shaft. Do not to drop the bearing and spacer.
5. Use a 2mm hex driver to remove the 4 button head
screws holding the composite rudder assembly to the
aluminum steering base.
Tip: The button head screws holding the composite
rudder to the steering assembly are different lengths.
The 6mm length screws go in to the bottom holes. The
8mm length screws go in to the top holes.
NOTICE: Using the 8mm length screws in the bottom
holes will damage the channel in the rudder that houses
the flex shaft. Damage to the flex shaft may occur.
6. Once you have removed the screws, remove the
composite rudder assembly from the boat. Apply
downward force while pulling it away from the boat.
7. Use a 2mm hex wrench to remove the 2mm counter
sunk screws joining the 2 pieces of the composite
rudder assembly.
8. Inspect the non-stick liner for wear and tear. Replace it
when necessary.
9. Use a hex driver to push the 7 x 2.5 x 4mm bearing
away from the housing.
10. Inspect the bearing for signs of wear. Use Dynamite
Precision Oiler: Medium (DYNE0100) to lubricate the
bearing if it does not need to be replaced. Use new
bearings and seals (PRB286053) as a replacement.
Tip: The spacer dimensions are 6mm x 2.66mm x
4.17mm.
