Overview

The Attwood Marine 17211-3 is a 3/4 in drain plug and receiver kit for small recreational boats, inflatables, and personal watercraft. The plug threads into its receiver and seals with an elastomeric gasket, and the receiver sleeve measures about 15/16 in for installations built around this compact drain size.

It replaces the full drain closure assembly rather than only the plug, which matters when the old receiver is worn, cracked, or no longer holding a clean seal. The molded black plastic body will not rust, and the retaining strap keeps the plug attached to the receiver so it is less likely to go missing at launch, haul-out, or storage.

Key features

• 3/4 in threaded plug size for small-boat and PWC drain openings that use this style
• Molded black plastic plug and receiver with a retaining strap that keeps the plug attached
• Elastomeric gasket helps seal the receiver against the mounting surface
• Includes mounting screws so the receiver can be replaced at the same time as the plug
• A practical fix when the existing receiver threads are worn or the plug no longer seats cleanly

Installation and fit

Fit matters more with drain hardware than with most small boat accessories. Check that your hull or transom drain uses a 3/4 in threaded plug and that the receiver footprint matches the existing mounting area before drilling or bedding the new part.

Because this kit includes the receiver, gasket, and screws, it makes sense when the old assembly is damaged or when a loose receiver is letting water track around the flange instead of through the drain opening. Install it on a clean surface so the gasket can seat evenly.

Use on board

This kit suits PWCs, tenders, inflatables, and small runabouts that are launched often and drained after use or after washdown. The attached plug is especially handy on boats that live on a trailer, where drain plugs are easy to misplace between trips.

For buyers trying to match an existing setup, the main checkpoint is the drain style rather than the brand of boat. If your boat already uses a compact 3/4 in threaded drain plug assembly, this kit is a straightforward replacement path.
