Does the job
by William from Cadillac, Michigan on August 21, 2012
Um, it's a nut and does what it's supposed to do. Pretty pricey for what it is though.

Cotter Pins
by Steve from Algonquin, Illinois on June 15, 2014
I ordered cotter pins with my new prop and hub kit and when I unpacked my package, I totally forgot about the cotter pins and recycled the box, cotter pins and paper insulation in all. In the future, I would suggest that you tape smaller parts to larger boxes so dummies like me won't toss them out.

Warning -- doesn't fit
by Kevin from Buffalo, Minnesota on July 31, 2014
The $36.99 thrust washer doesn't come close to working with my motor or prop that I ordered. Inside of washer is smooth, not for fitting the splines like shown like original thrust washer and in the washer image. It wobbled on the spline (washer inside opening is slightly too big) and would have pushed the prop so far back the aft washer would not go on. Reversing the washer direction causes the washer to get stuck on the prop (can't be installed that way). This washer came up as recommended on the website and a note that it would be required for the stainless steel prop I was buying. Prop is working with original thrust washer and this one is certainly wrong.

Looks OK
by William from Cadillac, Michigan on August 21, 2012
Ordered this along with the prop I bought. Thought I needed it, but it's not used with the prop. The prop ordering page was a bit confusing, but I have a spare now for my aluminum prop I guess.
