## Questions & Answers

**Q: Can you side mount these? My 1987 contender has rubber flappers like this but on sides of boat, not the transom.**
A: Hi Ashley,

This is intended for transom mount only.  We are launching another version in 2 weeks which is intended for Port and Starboard Mount.

Please contact us via our website and we can assist further.

**Q: is there one or two in the package**
A: Hello,

These are sold individually.

**Q: Where would I buy silicone seal replacement for this product**
A: Hello,

Silicone is a very stable material in the marine environment unlike other rubbers that are used with traditional rubber flapper scuppers.  Our seal is also protected from UV light by the stainless steel door.  It is designed to last a very long time.

However, if replacement is ever needed, simply reach out to Seaworthy Innovations directly via our website.

Best,
