I'm replacing the motor in my Hayward Tristar. I got everything buttoned up when I realized I had a leftover part! It's a rubber washer, and I'm certain it was located between the seal plate and the pump. I missed it on reassembly because there wasn't a replacement in the go-kit, and it also wasn't mentioned in the official Hayward video I was following. It's also not shown on the parts diagram at Inyo. I did get a new seal plate, and while there are some minor differences, I didn't see anything obvious in the flange that mates to the pump shaft. Rather than opening it up again, I'm leaning towards just ignoring this thing. If water makes it that far, it's already gone past the fancy ceramic shaft seal and disaster will follow shortly. I just wanted to check here if anyone has experience with this.

I was able to find my answer (from @1poolman1 previous posts of course). I found some Hayward seal kits with this piece included, called water slinger. I've seen this term before but didn't know what it was. Now I do. Previous messages say it's just a last line of defense for the motor bearings if the seal leaks, but doesn't provide much protection. I'll probably put it back in because it's in decent shape and I haven't put the pump back on the pad yet.

Yup, water slinger. They get hot, brittle, crack, lose contact with the motor shaft and then don't spin, sometimes get stuck right at the motor and you spend days looking for the squeak, and fall off. By the time you see water that they may sling the seal has probably been leaking for a while and you should change it.

If they come with a new motor, they get installed. If they are in good shape, they get re-installed. If they are brittle, cracked, gone they are gone.

The best thing you can do is to be aware of how your system works/looks. If you see water that you can't explain at the pad, especially under the pump, get it looked at. Replacing a $20.00 seal yourself or paying someone a service call to do it is more than worth the cost.
