Sounds like you've already replaced the shaft using JB Weld :)cf:), but just wanted to add to the the list as another person who has replaced a shaft using 271 red loctite (motor upside down & loctite on female threads). I also put a small bead of silicone around the last few remaining visible male threads before it was fully tightened (near where shaft goes from threaded to smooth). Going strong 1-2 years later.

Also, like WBG444 said, I cleaned the threads very well. I used a small pick and wire brush and went through all the threads with it, but the correct sized tap would work better/quicker. Same concept -- get all the old glue and fiberglass/plastic/whatever off the old threads.

I thought I found official Minnkota instructions on how to do this when I replaced mine but can't find them now.

Hope yours stays dry!

What is the thread count on that 1-1/8" tap?
1-1/8"-18rd is the thread pattern, but the Minnkota tap would certainly be a better solution if it has a hole through it for the wires. I may have to get one of those too...

Ya, I hope it stays dry too, being as I used JB I do beleive that having to repeat this process is going to be a much more difficult endevor.

Minn Kota uses Red Loc-tite #271 with #7090 primer. It's also what Northland Marine recommends as well, so it's what I've used with no issues so far, and I've done several.

I just removed an edge 70 shaft (original) and the sealant was not red loctite. It as very hard and gray, no red. I am waiting on parts from minn kota job seem simple enough the key is obviously getting the new shaft started straight. The lower half of the treads look new the upper half have been cleaned but still don't real good.
