Securing the prop.

[Eggy]

What do you guys use to secure your props? Up til now i have been using a standard non lock nut along with the bullet nut, and last run the boat flipped on me doing around 25mph in a turn. Dont know if it was the flipp that coused the prop to come loose or if it was the other way around.

I usualy thighten the inner nut with a socket along with an extender and tighten it with my hands untill its quite tight, then i use the slighly more pressure on the bullet nut.

The reason why i dont use a lock nut is becouse the drive shaft is not long enough to use the bullet nut aswell.

Should i trow away the bullet and just stick with a lock nut or do you have any other tips?

Thx

I use Locktite Blue with a crush nut and/or the bullet. It still holds and is easy enough to remove.

I have used all types of nuts, and have lost a prop on every one. I took a tip from the Nitro racers, and started using a piece of silicone fuel tubing as a nut. I can safely say that I have never NEVER lost a prop since.

One day with my Viper, then suddenly no fwd movement. Throttle spun but no movement. I remembered that I had pulled the fuel tubing off to swap props, I put the tubing on the very tip of the prop shaft, and forgot to slide it down to the prop. I thought I lost my first prop on fuel tubing. Got the viper back.
The prop was still there, the tubing (just on the tip) kept the prop on the shaft. because it wasn't seated all the way, the prop came off the dog is all. Still no lost prop.
Egneg was there for that famous run.

There are those that are going to say that it's not a good idea, and it probably isn't. But I can't argue with the results...

The regular nut and bullet should be fine if you use 2 wrenches and tighten them against each other like you would a flex coupling.

I use a wheel coller. Take a size smaller and drill and tap it to screw onto the shaft. Then use low strength permatex thread lock on the coller allen screw. It's worked so far.

For my smaller boats that run a 1/8" shaft I use a small piece of fuel tube on a smooth shaft.
For the bigger 3/16" shafts I use a very short piece of fuel hose and then a wheel collar pressed up to the tube and tightened.

As all of my shafts are smooth I can not get a nut on there anyway.

Makes for quick prop changes and I have not lost a prop yet.

I have never lost a prop using Nylock nuts. I like Diegoboys way though and will give it a try as it saves a lot of time when testing props
