Sea-Dog Transom Mount Ski Tow, Stud Style, 3/8"-16 NC, 316 Stainless Steel, 371631-1

The Sea-Dog Transom Mount Ski Tow, part number 371631-1, is a stud-style towing eye designed to bolt directly through the boat transom for maximum holding strength. Unlike surface-mounted hardware, this stud-style design passes through the transom itself, distributing towing loads across the mounting surface rather than relying on screws alone, making it a solid choice for pulling skiers, tubes, and wakeboarders.

It is formed from AISI 316 stainless steel rod, a grade chosen for its resistance to corrosion in saltwater and freshwater marine environments, so it holds up to repeated exposure without rusting or pitting over time. The tow features a 3/8"-16 NC thread and compact overall dimensions of 2-1/2 inches by 2-1/4 inches by 2-3/16 inches, keeping it low-profile against the transom while still providing a secure attachment point for tow ropes.

This is a standalone stud-style ski tow and does not require the additional flush-mount hole cutting that Sea-Dog's flush mount ski tow designs call for, making it straightforward to install on transoms that can accommodate through-bolting.
