1. Kayak Scupper Plugs G3 Self-Draining With Pull Loop
The G3 Self-Draining scupper plugs from Kayak Scupper Plugs represent the pinnacle of scupper plug technology. These innovative plugs combine functionality with user-friendly design, making them a top choice for serious kayakers.
What sets the G3 apart is its unique self-draining feature. While traditional plugs completely seal the scupper hole, the G3 allows water to drain when it reaches a certain level, preventing your kayak from becoming waterlogged during heavy rain or when taking on waves. The convenient pull loop makes installation and removal quick and easy, even when wearing gloves.
The G3 plugs are made from high-quality, marine-grade silicone that resists degradation from salt water, UV exposure, and temperature extremes. Their tapered design ensures a secure fit in a wide range of scupper hole sizes.

Ocean Kayak Scupper Stoppers are among the most popular options on the market, especially for owners of Ocean Kayak vessels. These plugs are designed specifically for Ocean Kayak models but can work well with many other brands that have similar scupper hole dimensions.
Made from durable rubber, these cone-shaped plugs create a reliable seal while remaining flexible enough to insert and remove without excessive force. The tapered design accommodates various scupper hole sizes, making them a versatile option for many kayakers.
The bright yellow color adds a safety element, making them easy to spot if dropped in the water. They also feature a built-in flange that prevents them from falling through the scupper hole completely.
| Pros | Cons |

YakAttack’s Scupper Plugs are designed with versatility in mind, featuring a soft rubber construction with a conical shape that fits a wide range of circular scupper holes. The hollow design is particularly innovative, allowing the plug to compress for a secure fit while maintaining flexibility.
These plugs come in medium and large sizes, making them suitable for most standard kayak scupper holes. The design includes a slight lip at the top that prevents the plug from slipping through the hole completely.

For kayakers seeking a perfect fit, custom scupper plug kits offer tailored solutions for specific kayak models. These kits typically include multiple plugs in various sizes designed to fit all the scupper holes on a particular kayak model.
The advantage of custom kits is obvious: perfect fit for your specific kayak. This eliminates the guesswork of trying to find universal plugs that might work with your scupper holes. Many custom kits also include pull cords for easy removal and storage options to keep your plugs organized.
These kits often use high-quality silicone or rubber materials that provide excellent sealing capabilities while remaining easy to insert and remove. The custom approach ensures you’re not compromising on fit or function.
| Pros | Cons |
|---|---|

5. Silicone Cork-Shaped Scupper Plugs with Pull Cord
These cork-shaped silicone plugs represent a simple yet effective solution for kayakers. Their tapered design mimics a wine cork, creating a secure seal that’s easy to insert and remove thanks to the attached pull cord.
Made from food-grade silicone, these plugs are exceptionally durable and resistant to UV damage, salt water, and temperature extremes. The silicone material provides excellent flexibility, allowing the plug to conform to slightly irregular scupper holes for a better seal.
The pull cord is typically made from marine-grade cord that won’t deteriorate in water, making these plugs easy to remove even after extended use. Some versions also feature bright colors for high visibility.
| Pros | Cons |
|---|---|
| Durable silicone construction | May be too flexible for some preferences |

6. Universal Foam Scupper Plugs
For budget-conscious kayakers, universal foam scupper plugs offer an affordable solution. These plugs are typically made from closed-cell foam that compresses to fit various scupper hole sizes while providing adequate water blockage.
The foam construction makes these plugs extremely lightweight and buoyant, so they won’t sink if accidentally dropped in water. They’re also easy to trim with scissors if needed to achieve a better fit for specific scupper hole dimensions.
While not as durable as rubber or silicone options, foam plugs are inexpensive enough to replace regularly and work well for occasional kayakers or those who only need scupper plugs in specific situations.
| Pros | Cons |
|---|---|
| Very affordable | Less durable than rubber or silicone |
| Lightweight and buoyant | May absorb water over time |
| Can be trimmed for custom fit | Provides less secure seal than other options |
7. Adjustable Scupper Plugs with Valve System
For kayakers who want ultimate control over water drainage, adjustable scupper plugs with valve systems offer a sophisticated solution. These plugs feature a twist-valve mechanism that allows paddlers to control how much water can pass through the scupper hole.
This adjustability is particularly valuable in changing conditions – you can keep the valves closed in calm water for a dry ride, then open them partially or fully when needed for drainage in rougher conditions or when taking on water.
The construction typically combines rubber or silicone with plastic valve components, creating a durable and functional system. Many models include easy-grip handles for adjusting the valve even with wet hands.
| Pros | Cons |
|---|---|
| Adjustable water flow control | More complex mechanism can break |
| Adaptable to changing water conditions | Higher price point than basic plugs |
| No need to remove plugs to drain water | Requires more maintenance than simple plugs |

Should You Plug Your Scupper Holes?
Before investing in scupper plugs, it’s important to understand when and why you might want to use them. Scupper holes are designed to drain water from your kayak, so plugging them isn’t always necessary or beneficial.
When to Use Scupper Plugs:
1. Cold Water Paddling – Plugging scupper holes can help keep cold water from entering through the bottom of your kayak, keeping you drier and warmer.
2. Fishing with Gear – If you’re carrying extra gear and sitting lower in the water, scupper plugs can prevent water from continuously entering through the bottom.
3. Calm Water Paddling – In flat, calm conditions, plugged scuppers can provide a drier ride without compromising safety.
4. Kayaking with Children or Pets – Keeping the cockpit area drier can improve comfort for young paddlers or four-legged companions.
When to Leave Scuppers Open:
1. Rough Water Conditions – In choppy water or waves, open scuppers allow water to drain naturally, preventing accumulation.
2. Heavy Rain – Open scuppers help rain water drain out rather than pooling in your kayak.
3. When Launching or Landing – Open scuppers allow water to drain quickly when entering or exiting the water.
4. Hot Weather – Some water entering through scupper holes can provide cooling on hot days.
Many experienced kayakers adopt a “best of both worlds” approach, using scupper plugs selectively based on conditions, temperature, and personal preference. Some plug only certain scupper holes (often those under the seat) while leaving others open for drainage.
How to Choose the Right Scupper Plugs
Selecting the appropriate scupper plugs for your kayak involves several considerations:
1. Measure Your Scupper Holes – The most important factor is getting the right size. Measure the diameter of your scupper holes carefully, as sizes can vary between kayak models.
2. Consider Your Kayak Model – Some plugs are designed specifically for certain kayak brands or models. Check if the manufacturer recommends particular plugs.
3. Evaluate Your Needs – Think about your typical paddling conditions. Do you need complete water blockage, or would self-draining plugs be more practical?
4. Assess Ease of Use – Features like pull cords or loops make plugs easier to insert and remove, especially with cold or wet hands.
5. Material Quality – Higher-quality materials like marine-grade silicone or rubber will last longer,
