## Questions & Answers

**Q: Need larger pin hole .0177 size**
A: .0177” is about 1/57th of an inch or .45mm. You would need a #77 (.4572mm or .018”) drill bit. I would say that’s a little too small.

**Q: How do I order the pieces in stainless steel? What are the part numbers?**
A: Search for stainless brackets.  I went with aluminum to reduce the weight in my Jon boat.

**Q: We have sp 67749 and sp 1002 seat mount.  How much force should be needed to fit them together? Opening in plastic insert seems too small for shaft.**
A: It will fit tight!  Push hard to get it in.  It will be even harder to get out!

**Q: How tall is the shoreline marine seat post?**
A: The post is 11". the base shown is 3/4" thick
