Sierra International 18-3735-9 Marine Cotter Pin - Pack of 10 , white

Value for money is great.. Does the job and you do not have to save the old pins (you have plenty to use)...

I have a new Yamaha F70 4 stroke and these cotter pins are heavier duty than the original pin on the castle nut. It still fit in easily when I greased the prop on the 20 hour service, but was a little longer and thicker than the Yamaha OEM, which is good. I am comfortable that my prop is staying put.

Got it quickly

Fit the Yamaha F115 perfectly. Slightly smaller diameter (and that is good) than the OEM. Non-magnetic stainless steel so should be fine. I use in salt water so we will see in a few weeks. There is no load on these all they do is keep the castleated nut in place. Perfect.

These were stainless as described but bigger than described. I was able to make this work.

What I like the most is that these will work perfectly for my propeller. Pay no attention to negative reviews on this cotter pin.

These are not even close to the yamaha oe pins. They are much smaller. Yamaha oe part is much bigger in diameter. I returned them because i would never trust them to perform well in extreme applications--like holding the prop on a boat motor in the middle of nowhere alaska. Amazon should pull them off the shelf until sierra international gets them right.

It fit as advertised.
