KIWI Shaft Seal Installation Setup

The new stainless steel KIWI Seal is lubricated by cold water (salt or fresh) through a water feed looped and vented above the waterline. The cold water fed through the seal cools the assembly and acts as lubricant for the bearing surface fitted at the end of the shaft seal carrier. It is an accepted good engineering practice to have the water feed line looped and vented above the water line.

The KIWI shaft seal must be fitted onto a stern tube that has a forward bearing that will support the shaft directly behind the seal.
