But this Eliminator prop helps you eliminate a lot if not all of that vibration. It's really easy to install. All. It is is one solid piece of aluminum with a rubber gasket around the edge that butts.

The ELIMINATOR Prop Nut is built to make your trolling motor perform better, longer, and quieter. Designed to lessen prop noise and vibration, The ELIMINATOR Prop Nut stabilizes the prop by providing a larger contact point.

Available in three different sizes to fit Minn Kota prop dimensions (3/8", 1/2" and 5/16").

The addition of a propeller spacer allows you to extend the propeller radius back away from the pilot. This can be done for more cage clearance as opposed to spacers on the motor mounts, which move the entire weight of the motor away from the pilot, decreasing comfort.

As mentioned, it's especially slippery, thereby protecting your valuable propeller shaft threads from galling. Brass is strong and relatively easy to machine, making it well-suited to the manufacture of nuts.

Installing Your Boat Propeller: Step #3 Once the nut is hand tightened, you may now use a torque wrench to reach the specification of 55 foot-pounds of torque. If you don't have a torque wrench, no need to worry, simply tighten down the nut with your socket.

1-1/16" Nut Prop Nut Compatibility: 1-1/16" Nut (the standard size nut for 1", 1-1/8", and spline shafts) Drain Plug Compatibility: 9/16" Square Head Garboard.

1 1/16” Removing Your Boat Propeller: Step #1 Now, you'll need a socket, usually 1 1/16” will do the trick, but if you have a socket set, we recommend having that handy as not all sizes are the same and can vary by manufacturer.

The purpose of the prop nuts is to make sure the propeller stays seated snugly against the shaft taper. In normal operation, prop nuts don't really take much load anyway, as thrust from the engine keeps the propeller pushing onto the shaft.

Like the thrust washer, the spacer assists alignment of the prop to the shaft when the inner hub is unable to hold its shape, only this time at the aft end of the prop. The spacer bears reverse thrust loads and prevents the inner hub from moving aft, with its large surface area.

Spacers are used in competition and track use, so as long as you aren't going with crazy offset and 20mm+ spacers you shouldn't see significant affect in performance. In fact a wider stance might be desirable to increase your track.

Brass fasteners are primarily an alloy of Copper and Zinc providing anti-rust, non-magnetic and corrosion resistant properties.

Brass nuts are used alongside a mating bolt or screw to fasten multiple parts together – with Brass providing specific characteristics that makes them the perfect choice for many modern applications.

Your nuts should have an anti slip material inside, so even if they get a bit loose they never go out of the screw. About tightness, just tight it until it bites the prop and you can't rotate it beneath the nut unless you make a lot of force to do so.

There are two key variables when it comes to the propeller: the first is the rotation speed and the second is torque. When you multiply rotation speed and torque together, you obtain mechanical power.

The inside of my nut measures approximately 0.65 five thousandths of an inch. We can see that that's not anywhere close to either twenty millimeters or three-quarters of an inch.
