Topper self bailer gasket

Replacement foam seal which fits in between the Topper cockpit and the self bailer.

A soft foam gasket which compresses over time so will probably need replacing if you're replacing the bailer. If your boat is leaking around the baileryou can also try Silicone sealant especially between the hull and deck moulding if leaking into the boat, the other place to check is a similar seal around the top of the daggerboard case
