Drivetrain Lubrication; Water Cooling System - ProBoat SonicWake Owner's Manual

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.
1. In the hull, use two 10 mm open-end wrenches to loosen
the motor coupler.
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.

Water Cooling System

If water does not stream out of the right-side water outlet
while the boat is moving forward, immediately stop the boat
and clean the obstruction from the water-cooling system.
1. Disassemble and clean the water cooling system to
remove blockage and prevent overheating.
2. Replace any damaged parts.
Instruction Manual
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.
CAUTION: Running a battery with less than 11.1V will
not provide enough momentum to engage the water-
cooling system and will cause damage to the electronics
due to excessive heat.
