Review on 🐾 Panther Marine 3005.5274 KPS50B Transom Mount Brackets - 5" Setback - Black: Ultimate Solution for Easy Transom Mounting by Robert Maysey

Features 304 or 440 stainless steel fasteners in the anchor clamping mechanism. It will rust in salt water if not rinsed thoroughly. I would recommend using CorrosionX or something similar. Also, O-rings are only suitable for a perfectly flat transom. Also, I don't trust the supplied self-tapping screws to attach them to the boat's aluminum transom. 3M 5200 seals better and increases the security of the attachment. For attachment to very thin sheet metal, it is better to use screws with washers on the inside or rivet nuts for blind mounting.
