Want a simple way to power a boat?
Drill a 4mm hole, push the shaft in from the back, hook up a motor with a 4mm shaft and go!
Universal means the motor can be mounted flatter or on an angle if necessary.
One Boat Drive Shaft Set, Universal joint and 3 Blade Propeller.
Inner shaft length: 30cm
Outer tube length: 25cm
Inner shaft diameter: 4 mm
Universal: Suits 4mm motor shaft.

There are two high speed bearings at the end of the shaft sleeve. Smear some butter on shaft before use for less friction and longer life.
