I have had it leak three times and the armature replaced twice by the dealer. Has anyone located the primary leak location??? Thanks

My bet is it is leaking where the shaft is molded to the motor housing. If it has leaked 3 times then I would opt for a new motor assembly because it will continue to leak.
Mine was leaking around the shaft seal and to my knowledge has never had any line around the shaft. Only way to know for sure is a pressure test with motor down in some water.
Thanks guys. I'll tear it apart myself and seal it right

the seal from where the fin meets the housing is known to fail. had it happen to me in the summer. you can get the rebuild kit (trollingmotorparts.com) i think thats where i ordered from. it simple to rebuild, i ordered extra brush plate,brushes,seal,springs pretty much anything you would need if it was to fail. after rebuild and assembly put some silicone around the fin to shaft connection the where the nose cone meets the shaft.

Rebuilt it today and found that the dealer here, that fixed it the last two times, didn't add the paper spacer between the two seals on the fin side. I cleaned everything really well with acetone and sealed each cone with silicone. Also siliconed around the 2d puck and where the shaft goes into the housing. We'll see how it works now. Very frustrating when you find missing parts from professionals you pay big bucks to....

The Paper seal is put on at the factory. It is just a spacer. It is not really necessary to have. Will not affect the leak problem. As suggested above a leak test with a source of air is recommended to test the whole motor assembly. Adding silicon seal will not fix the problem. The silicon will eventually come off. It will not stick to any part of the motor housing. I would be surprised if the leak is fixed.
I think you might be confused about the silicone seal. I put a bead of silicone over the O-rings where the parts fit together. The silicone is not on the outside it's in between the parts. That won't come out. Didn't know that about the paper spacer so thanks. How would you leak test the trolling motor with an air compressor?

If you have a big enough for the motor to fit in Take an air compressor and adjust the air pressure to 1-2# output. Submerge the motor assembly in the water so the motor is completely under water 1-2" or more past the place where the shaft enter the motor. Use something to prevent escape of air while you have the nozzle in the end of the shaft. Pressure up the motor assembly and if you have any leaks it will bubble out of the leak area.
Be cautious not to put too much air pressure in the motor assembly. With 1-2 # it should work well.
Heck you could probably do a couple #s by blowing down the tube with a tube taped around the top of the shaft. Might need another set of eyes or have a specified blower on the tube though.
Tell me where has a slow movin' once quick draw outlaw got to go
I was considering drill and tapping a little hole on the bottom with a sealed bolt to check for water intrusion once in a while.

Apply a bead of silk-a-flex around the shaft where it enters the motor housing.

Clean it before applying if it's dirty.

I'm pretty sure my leak came from the shaft and foot union, with added leaks at the seals.
The moisture caused heavy electroless in the aluminum. A complete replacement of shaft and motor will be the easiest fix.
