Installing a 70A Trolling Motor Plug & Receptacle on a Kayak

In this video, Duke and Irv walk through how to properly install a 70-amp trolling motor plug and receptacle on both a kayak and a trolling motor—using the Marinco 70A DC Plug & Receptacle as the example.

The install is shown on a Bonafide SS127, but the same process applies to most kayak brands and models. The goal is simple: clean wiring, solid connections, and a setup that can safely handle high current without overheating or failure.

⚠️ Proper connections matter. A poorly wired trolling motor plug can overheat, melt, or damage your kayak’s electrical system.
