Sea-Dog 371644-1 Stud Style Transom Mount Ski Tow, 1/2 Inch-13 Stainless Steel Stud

The Sea-Dog 371644-1 is a Stud Style Transom Mount Ski Tow built to bolt through the transom for maximum holding strength, giving boaters a secure attachment point for towing skiers, wakeboarders, and tubers. The tow stud is constructed of corrosion resistant AISI formed 316 stainless steel rod, a material chosen for its ability to withstand continuous exposure to fresh and salt water without rusting or weakening. The 1/2 inch-13 NC threaded stud passes fully through the transom and is secured from the inside, distributing towing loads across the transom structure rather than relying on a shallow surface mount. This makes the stud style design a strong choice for boats that see frequent towing use. The part measures 3-1/2 inches at dimension A, 3 inches at dimension B, and 3 inches at dimension C, and weighs 1.322 pounds. Sea-Dog also offers flush mount ski tows (371833 and 371840) that share the same stud center spacing as the 371644, so boat owners updating the look of their transom can step up to a flush mount version with the addition of a mounting hole, if desired.
