There is a magnet inside the barrier that is connected to the propeller shaft. When you assemble this thing you need to be real carful. The first time I slid the magnet assemblies together I almost lost a finger. If the propeller gets jammed, the magnet drive would slip like a clutch. It would take a lot though, my magnet drive is bigger than it needs to be. The propeller assembly can still
drop off in an emergency, that is all the same still.

It is kinda chunky at about 9in long. I can NOT overpower
the coupler by hand, it is incredible how strong it is. I pressure tested the assembly to 625 psi for one hr with no issues. I will oil fill the shaft tube to lubricate the outboard shaft bearing and protect against corrosion.
