EDSRDPLT 8 Pcs Kayak Scupper Plugs Kit with Silicone Handles, 2 Sizes Drain Hole Stopper for Kayaks Canoes Fishing Boats Review (2026)

What is included

This kit includes eight scupper plugs split across two sizes, generally four of each, meant to fit the different-sized drain holes found across a kayak, canoe or small fishing boat rather than assuming every scupper hole on a boat is the same diameter. Having two sizes in one kit means paddlers do not need to buy separate packs to cover a boat with mismatched hole sizes at the bow, stern and seat area, which is a common layout on sit-on-top fishing kayaks with multiple scupper holes spread across the hull for drainage. Keeping both sizes on hand also means a spare is ready if one plug is lost overboard mid-trip.

Material and handle design

The plugs are made from TPE, a flexible thermoplastic elastomer material chosen for its elasticity and ability to form a tight seal inside a drain hole without cracking or losing shape over repeated use across a paddling season. Each plug has a reinforced handle built for a secure grip, letting paddlers pull the plug free by hand without tools even when it has been sitting snugly in a hole through a wet trip. Non-slip strips on the plug body are meant to help it grip the inside of the hole and resist popping loose from water pressure while paddling in choppier conditions.

Sizing and hole diameters

The maker's published dimensions list the larger plug at about 1.8 inches across the top and 1.1 inches at the bottom, and the smaller plug at about 1.5 inches across the top and 0.7 inches at the bottom, tapered shapes meant to wedge into scupper holes of slightly varying diameter rather than one fixed size across every kayak model. The Amazon listing itself does not spell out these exact measurements, so buyers who want to confirm compatibility with unusually large or small scupper holes should check their kayak's hole size directly rather than relying on the listing text alone before ordering.

Installation and everyday use

No tools are needed to install or remove these plugs, since the tapered TPE body and handle are designed for a simple push-in, pull-out motion by hand rather than requiring pliers or a wrench. This makes it easy to open and close scupper holes on the water depending on conditions, plugging them to keep a kayak drier in calm water or pulling them to let water drain faster when taking on more spray or during a self-bailing situation on a sit-on-top kayak in rougher water or heavier loading. Carrying a couple of spares in a tackle box is a reasonable precaution since small plugs like these are easy to drop overboard.

Value and who should buy

Eight plugs across two sizes is a reasonable amount of coverage for kayaks and small fishing boats with several scupper holes, and the price point makes it a low-cost way to address unwanted water intake through unused drain holes around the cockpit and tank well. This kit suits sit-on-top kayak owners dealing with multiple scupper holes of different sizes across the hull. Paddlers with only one or two holes of a known, unusual diameter should double check fit against their specific hole size before relying on this two-size kit alone for a proper seal.
