Mercury Marine 69578Q1 Propeller Nut Genuine OEM product	$13.38~~$16.72~~ In stock Only 1 remaining	Best	OEM Mercury/Quicksilver kit with the correct nyloc prop nut and two tab washers for Mercury/Mariner 30–60 hp 2‑stroke and FourStroke, plus 25 hp FourStroke pre‑2006. The gold-finished nut in the photo has the white nylon insert Mercury specifies, and the washers match the OE tab style. Why BEST: guaranteed fit and thread pitch, proven corrosion protection and locking reliability, and hardware thickness that matches factory parts. Notes: a nyloc nut uses a nylon ring to create friction on the threads so it resists backing off; the tab washer is bent against a flat of the nut after torquing to provide a mechanical secondary lock.

EMP 11-00123 Prop Nut Kit (viewing this product) Aftermarket product	$12.23~~$14.39~~ In stock Only 2 remaining	Better	EMP aftermarket kit mirrors OEM but the nut is about 40% taller as seen in the photo, giving more thread engagement and a longer nylon contact area—useful on motors that see more vibration or frequent prop swaps. The black nylon insert functions the same as white; color does not affect locking performance. Includes two tab washers. Minor tradeoff: some aftermarket washers are a touch thinner than OEM, so bend the tabs cleanly and avoid reusing them many times. Overall a robust, good‑value upgrade with extra margin from the taller nut.
