## Questions & Answers

**Q: What size and length screws need to be used to install to the transom?**
A: If your transom is 2 inches thick, you need the next size smaller than 2 inches. If your transom is only an inch thick, don't install it at all, because your boat will sink. Cheers!

**Q: What sealant do you use with the plug?**
A: 3M 5200 Marine Sealant.

**Q: Is it metal or plastic**
A: Plastic

**Q: Can the plug be used independent of the mounting flange?**
