Boat owners with MinnKota trolling motors, this Eliminator prop nut is a simple upgrade that makes a noticeable difference! Specifically designed to work with MinnKota 80, 101, and 112 models (though it won't fit Kipawa or Hydrilla Hacker props), this replacement nut does two important jobs - it significantly reduces prop noise and vibration while stabilizing the propeller by providing a larger contact point. The built-in cooling ports act as a heat sink, reducing operating temperature which helps extend both your battery life and motor longevity. Machined from 6061 billet aluminum with an anodized finish, this thing is both anti-rust and built to last through tough marine conditions. Installation couldn't be simpler - just remove your existing prop nut and washer, then hand-tighten the Eliminator until it's firmly pressed against the prop face. The knurled edge design means no tools are needed for installation or removal. There's a gasket on the back that expands over time, so remember not to over-tighten. The difference in operation is actually pretty remarkable - much quieter and smoother than the stock nut, which makes for a more pleasant fishing experience. Whether you're dealing with annoying prop vibration or just want to optimize your trolling motor's performance and lifespan, this relatively inexpensive upgrade delivers real benefits. The quality machining is evident in the precise fit and finish, and it's one of those simple modifications that makes you wonder why it didn't come standard from the manufacturer. For serious anglers who spend long days on the water, reducing motor noise can actually improve fishing success since fish are less likely to be spooked by your approach.
