Builders frequently use very inexpensive plastic thru hulls. Sun, heat, and even the sealant they use can cause them to break down. If your thru hulls show signs of cracking, it's best to replace them before they break which could cause a hose to drain into your boat instead of overboard!
The scuppers on your boat are designed to drain while keeping water out. If yours aren't working, we can help you replace it or maybe just replace the parts that are worn!
