Review: Hardin Marine’s HMMA2 Series High-Performance Replacement Electric Hatch Ram Actuators

For boat owners looking to upgrade or replace their electric hatch actuator, the HMMA2 Series High-Performance 12v Electric Hatch Ram Actuators by Hardin Marine are a top-tier choice. These actuators deliver the perfect combination of power, durability, and smooth operation, making them a reliable solution for a wide range of marine applications.

Smooth and Reliable Performance
One of the standout features of the HMMA2 actuator is that is available in three different stroke lengths, 10″, 16″ and 22″, which provides ample movement for opening and closing engine hatches, storage compartments, and other marine access points. These actuators are designed to replace older 12″, 18″ and 24″ stroke hatch actuators respectively as closed length on the HMMA2 actuators is very similar to the closed length of other brands such as Thomson, which have become prohibitively expensive in the last year. The HMMA2 actuators operate smoothly and quietly, ensuring reliable function without jarring or abrupt movements. Whether you’re lifting a heavy engine hatch or securing an essential compartment, this actuator performs effortlessly.


Built for Marine Environments
Durability is a key factor when choosing marine hardware, and this actuator doesn’t disappoint. Designed to withstand harsh saltwater conditions, it features corrosion-resistant materials and a rugged construction that ensures long-lasting performance. The heavy-duty build provides excellent resistance to wear and tear, making it a worthwhile investment for any boat owner.
Easy Installation and Compatibility
Another major advantage of this actuator is its straightforward installation. It serves as a direct replacement for many existing hatch actuators despite the shorter stroke length, eliminating the hassle of extensive modifications. The plug-and-play compatibility allows for quick and easy integration, so you can get back on the water without any complicated setup. Two wires are all that are required for up and down movement, but the HMMA2 actuators are equipped with wires for hall sensors if so desired. You can also pair it with a hatch sync controller in order to keep dual ram set ups moving in unison, preventing damage if hatch rams accidentally move at different speeds.


Impressive Lifting Power
With high torque output, the HMMA2 actuators are capable of handling heavier loads than many other models with ease. Whether you have a large offshore powerboat or a high-performance speedboat, this actuator has the power to lift engine hatches effortlessly. The precise and controlled movement ensures safe and reliable operation every time.
Final Thoughts
Overall, the HMMA2 Series High-Performance Replacement Electric Hatch Ram Actuators are a fantastic upgrade for anyone looking for a powerful, durable, and easy-to-install marine actuator. Its high-performance capabilities, rugged construction, and seamless operation make it one of the best choices on the market. They are cost-effective and stronger than most competitors, with the only minor drawback being reduced stroke length. However, proper positioning of the ram will overcome this problem with ease.
If you’re in need of a reliable replacement hatch actuator, these hatch ram actuators are highly recommended option!
