Thank you for the follow up. When I ordered the lower unit from Minn Kota I asked the tech guy and red locktite was his answer. I saw this on the trolling motor webpage also. I’ve used red locktite a million times over the years but never in a specific water tight location. I did heat the lower unit to remove the tube and it turned out cleanly , just like red lock tite does! So, I guess they know a thing or two about using it for a sealant also. Thanks again, Hank
