PRIME Spacer rings

Spacer rings (also called spacers) are installed between the stern tube and the AFT seal housing.
The ring improves the durability of the liner and ensures a new, clean running surface for the seal rings.

Spacers can be installed without removing the propeller. Watch the animation.
