Lubricating the flexshaft 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 box.

Lubricate the flexshaft, propeller shaft

and all moving parts after every 2–3

hours of operation.

 1. Use two 10mm wrenches to loosen

the collet nut.

 2. Remove the hex screws holding

the prop strut in position. Remove the

entire assembly with the flexshaft.

Carefully note how the drive shaft and

prop are factory installed. This is import-

ant so that when you have finished

lubricating the drive shaft, you can

correctly reinstall the drive shaft.

 3. Remove the drive shaft by sliding it

out of the stuffing box.

Wipe off all dirt or debris from the

flexshaft and liberally lubricate the entire

length of the drive shaft with silicone

cable grease.

Carefully reinstall the drive shaft, making

certain that there is a 1–2mm gap be-

tween the prop strut and the drive dog to

allow for flexshaft shrinkage under load.

Note: Running the Blackjack 26 SS

Brushless EP RTR in salt water could

cause some parts to corrode. If you run

the boat in salt water, rinse it thoroughly

in fresh water after each use and

lubricate the drive system.

Because of its corrosive effects, running

RC boats in saltwater is at the discretion

of the modeler.

Section 10: Lubricating the Drive Shaft

Leave a 1mm–2mm gap

here to allow for flex shaft

shrinkage under load.
