[C320-list] Jabsco Impeller kit

[Warren Updike]

The stock impeller comes with the "O" ring, as it fits a number of pumps. My
pump uses a gasket not the "O" ring. I've made new gaskets using gasket
material purchased at an auto store, and keep several onboard. I coat the
gasket with Teflon grease before using. They survive many openings.

FYI I don't use the 10-blade impeller choosing to use the Globe #65416
"Run-Dry" blue 6-blade impeller.  I get these from Defender.com.  I have
verified that the 6-blade is as efficient as the 10-blade; and, they last
longer in my experience.  

It seems the price of impellers has nearly doubled over the past 3 or so
years.

Yesterday when changing the impeller I noticed in the kit an extra black
rubber gasket ( like a thin rubber band) along with the regular cover
gasket. I didn't see that anywhere when taking the impeller out of my water
pump. Beside my M30 Perkins the kit is also Volvo, Kolher, Northern lights
etc. Does anyone know if the rubber band gasket is for one of the other
engines and not necessarily for my M30 Perkins? If it is for the Perkins
where does it go I have never seen a gasket like this in an impeller kit.
