Fit is great. Instal is easy. Would buy again. ### ⭐⭐⭐⭐⭐ Works great *by G***Y on March 9, 2026* Completely stopped my leaking issue ### ⭐⭐⭐⭐⭐ Great replacement for my old plug *by N***D on September 9, 2023* This was almost and exact match to the original boat plug in my ‘02 procraft. It does seem to want to cross threat at times but I always make sure it seats correctly before tightening down, takes an extra 2 seconds. Really like the rubber O ring, makes a great seal. I also packed the edges with marine goop before tightening down, no leaks ## Frequently Bought Together - T-H Marine DP-1-DP Self-Retaining Boat Transom Drain Plug - Black - 3M Marine Adhesive Sealant Fast Cure 5200 (06535) Permanent Bonding and Sealing for Boats and RVs Above and Below the Waterline Waterproof Repair, White, 1 fl oz Tube - Attwood 17211-3 Drain Plug and Receiver Kit, ¾-Inch Diameter 1-Piece Plug, Threaded Receiver, Molded Black Plastic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/1708003-t-h-marine-drain-plug-self-retaining-screw-type-boat](https://www.desertcart.id/products/1708003-t-h-marine-drain-plug-self-retaining-screw-type-boat) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-14*
