YakGear Scupper Stoppers Review 2026: Best Scupper Plugs for Sit-On-Top Kayaks

2026-10-21

TL;DR

If water pools on your deck every time a wave rolls by — or you just spend the day sitting in a cold puddle — you need scupper plugs. The YakGear Scupper Stoppers are a simple, affordable fix: tapered foam plugs that seal your hull's drainage holes and keep your deck noticeably drier on flat water and calm-condition paddles. For the price of a fast-food lunch, this is one of the best quality-of-life upgrades you can make to any sit-on-top kayak.

Why Every Sit-On-Top Kayaker Needs Scupper Plugs

Sit-on-top kayaks are self-bailing by design — those holes drilled through the deck (scuppers) exist so water drains out automatically. That's a lifesaver in rough surf or when you're re-entering after a capsize. But on a calm lake, a flat reservoir, or a slow-moving river float, those same holes let just as much water in as they let out.

The result? You spend the whole paddle sitting in an inch of cold water. Your gear gets wet. If you're kayak fishing, that means soggy tackle bags, wet electronics, and a damp seat cushion from launch to takeout.

Scupper plugs block the holes when conditions are calm so water stays on the outside of the hull where it belongs. When conditions change — or you want to restore full self-bailing — you pop them out. It's a five-second swap that makes a real difference on any sit-on-top.

Specs & Features

The YakGear Scupper Stoppers come in a multi-pack with several tapered sizes to fit the most common scupper hole diameters (typically 3/4 inch, 1 inch, and 1-1/4 inch). Here's what you need to know:

• Material: Closed-cell foam with a tapered plug design for a secure, leak-resistant fit
• Sizes included: Multiple diameters in one pack to fit most sit-on-top kayak configurations
• Retention cord: Many sets include a short tethering cord to prevent plugs from floating away when removed
• Weight: Near-zero — stash a spare set in your day hatch and forget they're there
• Compatibility: Fits most popular brands including Wilderness Systems, Perception, Pelican, Lifetime, Old Town, and Sun Dolphin sit-on-top kayaks

The foam construction is the key differentiator. Foam compresses slightly into the hole for a snug fit without tools or force, then pulls out cleanly when you want drainage back. Rigid silicone and plastic alternatives exist, but foam tends to seal better on older kayaks where scupper holes have widened slightly from wear.

Which Size Do You Need?

Most sit-on-tops have two or three different scupper hole sizes across the hull — smaller holes near the bow and stern, larger ones under the seat where water pools most. That's why a multi-size pack is worth it over a single-size set. If you're unsure of your kayak's scupper dimensions, a quick measurement with a ruler takes 30 seconds and saves you a return trip.

Pros & Cons

• Tool-free installation and removal in seconds
• Multi-size pack fits a wide range of sit-on-top hull configurations

• Easy to lose if you don't use the retention cord
