Boat owners, this scupper flapper kit is one of those simple but essential maintenance items that can save you from big headaches later! The kit includes two black rubber flappers - one 1/2 inch and one 1-3/4 inch - plus all the necessary mounting hardware you need for installation. These replacement flappers work with both stainless steel and plastic thru hull scuppers, making them super versatile for different boat setups. The rubber material is durable and flexible, creating a solid seal that prevents water from backing up into your boat while still allowing proper drainage. Installation is straightforward - just remove your old worn-out flapper and replace it with the new one using the included keepers and fasteners. What's great is how this small repair can prevent major water intrusion issues that could lead to electrical problems, mold, or structural damage. The flappers are designed to open easily when water needs to drain out but close tightly to prevent backflow, especially important when you're taking on waves or backing down. At just 0.1 ounces each, they're lightweight but tough enough to handle marine conditions. Keeping your scuppers functioning properly is crucial for boat safety and maintenance, and this affordable kit lets you do preventive maintenance before problems develop. It's one of those boating essentials that every responsible boat owner should have in their maintenance kit. The quality feels substantial and they're built to last through seasons of use in saltwater or freshwater environments.
