Hi,
when I drained the shaft lube and refilled the new oil immediately began seeping out behind the prop.
I s there a seal back there that I need to replace???
Thanks.
 
Yes, and it can be done without disassembling the LU.

Drill a small hole in the metal shell of the seal, screw a sheet metal screw into that hole, and pull gently--sometimes two screws at once are required (with a gentle pull on one then the other).

The new seal can be tapped into place with an appropriate piece of pipe.

O.K I now have two seals which i am told are necessary to solve the problem. However my (Clymer) manual describes removing the prop and various bits of the hub assembly but does not mention any seals???
