Lewmar 360759999 Replacement Seal — New Standard Portlight, Size 1
Keep your Lewmar portlights watertight with this genuine replacement seal for the Lewmar New Standard Portlight in Size 1. Designed specifically for the new-style standard portlight series, this seal fits precisely into the frame channel to create a reliable compression seal between the portlight frame and the opening lens — preventing water intrusion at the hull side or cabin top.
Portlight seals are a maintenance item. Salt, UV, and repeated opening cycles cause the rubber to harden, crack, and lose its ability to compress and seal. Replacing the seal is a straightforward repair that restores full weathertight performance without replacing the entire portlight assembly.

Parts Desk Insights
Lewmar sizes their portlight seals by number — confirm your portlight size before ordering, as seals are not interchangeable between sizes. The size is typically marked on the portlight frame or can be found in your boat’s documentation. Also confirm you have the New Standard series, not the older standard or Ocean series, as the seal profiles differ. For other sizes in this same series, see the Lewmar New Standard Portlight Seal Size 0 and the Lewmar New Standard Portlight Seal Size 4. SKU: 239-360759999.
