EMD M3624UHD Bracket Designed for Minn Kota Instinct Quest – Bar Crusher 615HT Install

We installed a Minn Kota Instinct Quest 72″ trolling motor on a Bar Crusher 615HT using the EMD ultra heavy-duty M3624UHD bracket.

The M3624UHD has been purpose-built for the oversized Instinct Quest, featuring a larger footprint, thicker wall sections and transverse cross-bracing. In 3D simulations, the bracket showed only minimal elastic deflection under a 200 kg load, confirming its strength and rigidity.

For hull mounting, we used seven M8 stainless steel bolts along with ten 6.4 mm aluminium structural rivets, providing up to 9,000 kg of tensile strength and 6,500 kg of shear strength to handle extreme marine conditions.

In this video, we used a custom aluminium adapter plate as an alternative to the Minn Kota quick-release plate, which retails close to AUD $1,000. The adapter shares the same mounting hole pattern; however, we still recommend the genuine Minn Kota quick-release plate when using the M3624UHD bracket.

We also cover key installation steps often overlooked, including the use of marine-grade sealant and Tef-Gel on stainless fasteners to prevent galvanic corrosion.

The end result speaks for itself.
Big thanks to AMC for the workshop space, Lee and Lucas for the quality install. Thanks to AMC gold-level salesman Damian for his support throughout the process, and also to Joe from AMC for all the help he provided!
