How To help Needed

[george]

Hello
I have a build project that is NOT a submarine BUT I need some advice from here. I have a tracked vehicle build that is both land and water capable. It is a water surface runner but the the drive shafts go through the hull to the track sprockets. How do I seal that shaft so that water will not find it`s way inside and still have smooth shaft rotation to drive the sprockets?
Pictures work best for me.
Thanks in advance for your help.

That sounds familiar! Look at this: https://youtu.be/nWrWKm95kCE (1:37) Dennis Allen's amphibian.

I recommend cup-type seals. Like these:

Yes, That looks like the answer! I just have to measure and find the right diameter cup seals and brass. Thanks for your time and help and Yes my build is the same thing BUT in 1/16.
Thanks again for your help and Sorry for the late reply.

They don't have them. The Internet is your friend.
