Insert the bolt through the propeller so the head of the bolt is away from the notch on the propeller.

-
Put a drop or two of Purple Loctite on the tip of the bolt and screw the not onto the bolt so it spreads the Loctite down the threads.
-
NOTE: Loctite is not a glue, but a thread lock. Without using Loctite, the bolt (with propeller attached will spin out of the propeller adapter (it will unscrew itself instead of pushing the ROV through the water).
-
You will lose your propeller to the bottom of the pool. Loctite is a thread lock, which will lock the bolt and screw in place. With the appropriate force Loctite connections can be removed.
-
Normal ROV operations will not do this, but you can remove the propeller from the motor if needed.
-
To remove the propeller, use pliers, needle nose pliers, and/or a screw driver. That will provide the force needed to remove the propeller.
-
Do not forgo using Loctite for fear that you will be able to remove the propeller. Loctite is designed to be removable.
