Let’s Dive into Sierra International 183702D 183702D Prop Nut Kit

There’s nothing quite like the feeling of open water and a reliable motor pushing you forward. But, like any piece of machinery, outboard engines require regular maintenance, and sometimes even a simple part can leave you stranded. Enter the Sierra International 183702D 183702D Prop Nut Kit, a small but vital component designed to keep your Mercury/Mariner 30-60HP outboard running smoothly.

My journey to finding this kit began after a particularly rough weekend fishing trip, where I noticed excessive vibration and a concerning wobble in my propeller. It turned out the prop nut and washers were worn, threatening the entire prop assembly.

Upon unboxing, I immediately appreciated the simplicity and solid feel of the kit. It included the prop nut and two tab washers, all seemingly well-made and ready for installation. I had been eyeing similar kits from Mercury Marine and GLM, but the Sierra International offering seemed to provide comparable quality at a more reasonable price point.

My first impression was one of relief – a simple, affordable solution that could potentially save me a lot of hassle and expense down the road.

The kit seems durable, showing no signs of rust or corrosion despite constant exposure to saltwater.
