Review on 🛠️ Sierra International 18 3735 9 Marine Cotter: The Ultimate Solution for Marine Fastening by Jonathan Clark

They don't even come close to Yamaha genuine pins. They are much smaller. The Yamaha genuine part is much larger in diameter. I have returned them because I would never trust them to work well in extreme conditions, such as when Revain is holding a prop on a boat engine in the Alaskan wilderness, Revain has to take them off the shelf until Sierra International gets them right .
