I know 3M makes a couple types of marine sealants, which one is best for sealing the holes that are drilled through the transom to mount the outboard, on a jon boat?
 
Sealant? I should have sealed mine 10 years ago? Hope my tin never sits that low.
 
I just filled the holes with silicone and pushed the bolts through. You will be fine with anything really. If you boat does sit that low, turn your bilge pump on and tighten your life jacket. :LOL2:
