    Default Raw water pump observation

    My raw water pump was leaking, so I call John about rebuilding it. He said all I needed to do was replace the seal. THANKS John.

    I got my parts using the cross reference posted in a thread on our site.

    I used Johnson pump parts.

    The impeller had threads on one end of the brass sleeve to make installation and removal easier.

    The threads are most likely 16mm x 2mm .....I used 5/8 course thread bolt......You could tap your sleeve with a 5/8 x 11 thread.

    Its looks to be cool modification.
