So I had a buddy shoot a small hole into the cone part of my trolling motor. I didn't notice it was there until I saw some rust leaking out of it. So I guess I ran it a few times with water inside the motor. I was just curious if anyone else has done this and if so, did it eventually ruin the motor. I sprayed some lithium grease inside the hole to try to prevent rusting and I plan on sealing the hole, but was wondering if I should be looking for a new troller or if it will last.
