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

Perfect for Yamaha F115. Slightly smaller diameter (and that's a good thing) than the OEM. Non-magnetic stainless steel, so should be fine. I use in salt water so we'll see in a couple of weeks. They don't weigh on them, they just hold the crown mother. Ideal.
