  • boat prop

    Anyone know how to build a boat prop ? Wanna make a mud motor and it would be fun to make a prop too. Any ideas?

    My Mud Motor prop looks like a trolling motor prop, 2 blade made of stainless I think. I've rounded the edges and beat the heck out of it in rock bottom rivers and it keeps going.
    I'll never buy another mud motor without electric start, pull starting a direct drive 6' shaft filled with grease in winter is a workout.

      Mud motor and mud prop, thats a new one on me.

      Stainless would be the way to go but it don't give too easy and could bend a prop shaft or something else when hitting rock.

      I'd probably get a real stainless prop that is destined for the scrap yard and work on it. Most have a rubber hub that will give way if you hit something solid enough and may help with vibrations a little if the blades aren't exactly the same.

      Is a mud rig just for mud? or something thats used in a more swampy area?

      I'll have to google this thing.

        Google MudBuddy or Beavertail mud motors.

          I looked it up last night, I would have never knew.

          I helped in a prop shop for years and never heard of such a thing.

          We have lakes so I guess nobody around here uses it.

          Thanks for sharing.

            Very similar are the Thai long-tail boats, which have been around since the late 30's. They come in all sizes. One of these days I'll get some relatives to send me a fit of parts.

            Check out some of the small racing boat videos:
