Review on πŸ› οΈ Sierra International 18 3735 9 Marine Cotter: The Ultimate Solution for Marine Fastening by Patrick Bacho

Revainrating 5 out of 5

The reinforced pin fits my Yamaha outboard perfectly.

I have a new Yamaha F70 4 stroke and these cotter pins are designed for heavier conditions than the stock castle nut pins. It still fit easily when I lubricated the post after 20 hours of service, but it was slightly longer and thicker than the OEM Yamaha, which is a good thing. I feel comfortable that my support stays in place.

Pros
  • Easy to use
Cons
  • Older model
