【Perfect Fit for In-Floor Drains】 Specifically designed for vintage aluminum boats with in-floor drainage systems (Bottom of the hull). This 3/4"-14 NPT plug is a premium replacement for Crestliner boat accessories, ensuring a precise fit for older models that require an in-floor drain rather than a transom drain.
【Marine-Grade 316 Stainless Steel】 Unlike standard aluminum or plastic plugs, our boat floor drain plug is forged from high-quality 316 Stainless Steel. It offers superior corrosion resistance in both freshwater and saltwater, preventing thread seizing and ensuring lifetime durability.
【Ultimate Leak-Proof Protection】 Equipped with a high-density Neoprene sealing ring, this boat plug provides an airtight and watertight seal. The gasket compresses perfectly against the drain seat to prevent any leakage during docking, transport, or long-term storage.
【Effortless Hand Installation】 Featuring an ergonomic head design for easy hand-tightening. The precision-machined threads allow for a smooth, tool-free installation into your existing 3/4" NPT drain opening. Ideal for quick drainage during trailering or maintenance.
【The Reliable Restoration Choice】 A must-have for boat restoration projects. Whether you are repairing a classic runabout or maintaining a fishing boat, this heavy-duty 316SS plug replaces worn or missing factory parts with a modern, rust-proof upgrade.
