Impeller and wear ring ?

[75 Eliminator]

What is best way to measure my impeller and wear ring ?
thanks.

With an I.D. micrometer or diak caliper for the wear ring and an O.D. mic or caliper for the impeller.

Just for giggles just to see if it would work I used clay between the wear ring and impeller...and it worked pretty darn good! Almost like claying for valve/piston clearance. I had the clay in three locations, top, bottom, left, right.
Took a few times to get the feel how I needed to pull the impeller off so not to disturb the clay but yea it worked. I found I had to oil/lube the impeller area and the clay surface first.
NOTE...keep in mind, my Impeller was zeroed out on my shaft. A Impeller not trued on the running shaft will have some run-out thus, the clearance will be less and greater at some locations as the Impeller turns.

I used clay between the wear ring and impeller
I did this with my son's playdo to figure out a starting point for the length of my cam's thrust bearing/button :)

When I tried Playdough it was a little to spongy...modeling clay held the shape perfectly ;)

ya playdo is more spungy than clay, i just didnt have any clay and had a ton of playdo :D :D

The parts are out of the boat, I am rebuilding the pump and looking for an impeller for the boat.
