CMC Marine: Pioneers of Hydraulic Outboard Motor Control

CMC Marine (Cook Manufacturing Corporation) has been a cornerstone of the recreational boating industry since 1956. Since its founding, CMC has been serving oilfield, marine, industrial computer, and hydraulic markets. Over the decades, the brand carved out a unique niche by focusing relentlessly on one thing: giving boaters precise, reliable control over their outboard motors. CMC is the company that originated and pioneered self-contained hydraulic jack plates — an innovation that transformed how anglers and recreational boaters handle shallow water, trim, and motor positioning.

A Legacy of Hydraulic Innovation

CMC has led the way with its patented Power-Lift hydraulic jack plates for more than thirty years, as well as with its aftermarket tilt & trim products for more than two decades. This depth of experience is reflected in every product the brand engineers. CMC's hydraulic system is made of 100% non-ferrous materials, which makes it more impervious to saltwater and freshwater than ball screw, electro-mechanical systems equipped on other brands. The CMC hydraulic system is completely sealed and submersible, and it is constructed of 6061 T6 alloy aluminum extrusions fastened with stainless steel fasteners for maximum strength and durability.

At the heart of the CMC lineup are their renowned Trim and Tilt Units — comprehensive systems that deliver power trim and tilt capability to outboard motors of all sizes. Whether you're navigating skinny water or optimizing your hull angle for speed and fuel efficiency, these units give boaters a meaningful performance edge. Complementing them are CMC's Tilt/Trim Motors, the dedicated drive components that power these systems with the hydraulic force CMC is known for.

Jack Plates and Transom Hardware

CMC's Jack Plates represent perhaps the brand's most celebrated product line. CMC was the originator and pioneer of providing a self-contained hydraulic jack plate, and that legacy of innovation continues today with offerings ranging from manual static plates to high-speed hydraulic Power-Lift models. The jack plate's built-in setback enhances boat stability and puts the prop in cleaner water, giving the prop a better "bite" and eliminating prop slippage.

Rounding out the CMC product range are Outboard Motor Transom Pads and Support Plates, which provide critical structural reinforcement between the motor and transom. These components ensure that the full force of a CMC hydraulic system — or any powerful outboard — is properly distributed, protecting the boat's hull over years of hard use.

Part of the T-H Marine Family

In 2008, CMC proudly became part of the T-H Marine family, one of the largest manufacturers of recreational boating accessories in the world. Together, CMC Marine and T-H Marine are far and away the largest manufacturer of jack plates in the world. All major components of CMC products are engineered and manufactured in-house at the CMC facility, ensuring consistent quality and performance that boaters worldwide have come to rely on.
