Need Help Locating Prop For Older Electric Trolling Motor

[nootkan]

Hi all, been a while since I used this forum and just found it via a search. My problem is I was given an Eska Electric Trolling motor model number 18061A 36lb thrust 20 speed, along with a small fiberglass dinghy and the prop is broken. I have tried to find a replacement online or something similar that would work but no luck so far. Thought I try a few forums to see if there is another way to resolve this or a different prop that may work. The prop shaft is 9.525 mm (3/8inch) in diameter and the prop hub is very small roughly 1" in diameter. The hub fits inside the gear case not over it. It also uses a pin lock to hold it on. The length of the 2 blades from point to point is 6.5". I was able to use super glue to fix the original one temporarily and tested in a freshwater tank for a long period of time but I know that the first debris I encounter on the water will most likely break it again which is why I am looking for another option. Any advice or help greatly appreciated.

Couple of ideas

-Try EBay great source for unusual items
- See if you can find a different prop that fits or can be modified to fit.
- Have a friend with a 3D printer who can make one for you
- Sell this unit and buy a working motor

Hope this is helpful.

Highly doubtful that this is totally custom design. Just take the prop off and count the splines on the output shaft - then search online. Old Evinrudes used a shear pin style coupler (if there are no splines on the shaft)

Thanks for the replies much appreciated. Would wrapping bailing wire around the prop base to keep it from falling apart after contact with debris affect the balance or hurt the drive?
