O Ring on backing plate is all that is needed...

If the backing plate is flat and the O Ring properly seated there is no need for an additional gasket made from anything.

I read through the Moyer Flange Install document when I researched replacing my O Ring.

I have recently replaced the O Ring gasket on the backing plate.

I cleaned it(backing plate) up gently and on advise here used marine grease in the O Ring slot to hold the O Ring in place during plate tightening.

Using some lubricant on the impeller is a good idea just to be sure you don't run it dry.

I tightened using an "X" shaped pattern to be sure to have best chance at flat mounting.

The backing plate does not leak.

Best with finding your missing blades. Hope they are nearby right at the entrance to the water jacket injector.

All best.
