Groco TD-500 Garboard Drain with Square-Drive Plug

The Groco TD-500 is a marine garboard drain designed to simplify bilge water removal when your boat is out of the water. This through-hull fitting installs from the outside of the hull, allowing you to drain accumulated bilge water while your vessel is stored in a cradle, sling, lift, or on a trailer.

Key Features:

• External installation for easy access and maintenance
• Square-drive plug allows draining from outside the hull
• Eliminates the need to enter the boat to drain the bilge
• Durable marine-grade construction for long-lasting performance
• Prevents water accumulation during storage periods

The TD-500's square-drive plug design enables quick and convenient bilge drainage without requiring access to the interior of your boat. Simply remove the plug from the outside when your vessel is out of the water, and gravity does the rest. This practical fitting is an essential component for proper boat maintenance and winter storage preparation.
