Maintenance

Drivetrain Lubrication

Always replace the drivetrain parts when they are damaged
or show visible wear or injury and damage may result.
Lubricating the drive shaft is vital to the life of the drivetrain.
The lubricant also acts as a water seal, keeping water from
entering the hull through the stuffing tube.
Lubricate the drive shaft and all moving parts after every 20
minutes of operation.
Remove one flex shaft at a time, or mark the shafts as right
or left. The shafts are directional and if installed improperly,
severe damage to the shaft assembly and housing will result.
1. In the hull, use two 10 mm open-end wrenches to
loosen the motor coupler (C).
2. Slide the drive shaft out from the stuffing tube and drive
strut at the rear of the boat.
3. Wipe the old lubricant and material from the drive shaft.
NOTICE: When lubricating the flex shaft, do not lubricate
the first 20mm of the flex shaft. If grease gets into
the motor coupler, it may cause the flex shaft to slip
inside of the coupler, thereby damaging it and requiring
replacement.
4. Carefully reinstall the drive shaft, ensuring that there is
a 1–2mm gap between the propeller strut and the drive
dog. This will allow space for the shaft as it shrinks
under load. Without space, the drive dog could damage
the aluminum propeller strut.

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.
NOTICE: The counter-rotating propellers must rotate
inward. The clockwise propeller goes on the left and the
counterclockwise propeller goes on the right.

NOTICE: Ensure the flex shaft is installed correctly.
Installing the flex shaft incorrectly may result in irreparable
damage to the boat.
5. Carefully push the flex shaft into the motor coupler,
making sure the grease does not carry into the coupler.
6. Tighten the coupler using two 10mm open-end
wrenches.
NOTICE: Running the boat in saltwater could cause some
parts to corrode. If you run the boat in saltwater, rinse
it thoroughly in freshwater after each use, lubricate the
drive system, and flush the coolant system.
