Bevel Prop Washer

Merc Flow Torque prop hub uses 3 washers and a self locking nut. The only one so far that isn't just a flat washer is the bevel (or conical) type. All dimensions are accurate except for maybe the Height. My caliper's jaw was not made so I could get to outer edge of each side. I should have layed it flat and used the depth to get it, but reinstalled and don't want to take it back off unless needed

So I'm looking to find where these can be obtained. The other flat washers will not need to be replaced, and with a Nut and washer kit 840383A2 cost of $50, I'm looking now to see what can be found

While I recall seeing a few beveled type washers here and there over the past years, at the moment finding a new one isn't ringing a bell yet but mostly wanted to mention that the Prop locks from Mcgard uses a beveled type washer that has to be installed a certain way out that may work out for what you're wanting to achieve.

Is this washer on your/a bravo drive or something older, etc.?

This is on my Verado's, note washer "d" orientation.
Have discovered the industry seems to call them spring and conical washers

It is close, and it doesn't look like stainless but also don't see it rusting either

most likely 17-7ph. should have a dull greyish tint. will eventually "patina" in salt water. the 300 series bellevilles loose their springiness when flattened.

Does have dull grayish color
