E12026 Universal Stern Drive Autopilot Actuator

The Raymarine E12026 Universal Stern Drive actuator is designed to bring flexibility and broad applicability to autopilot installations on boats with stern drives. While the standard sterndrive unit (M81138) targets specific models and years of MerCruiser and Volvo Penta, the universal version (E12026) offers solutions for older or more varied stern drive setups, including those without factory autopilot interfaces. It comes with adapters and a range of universal fittings that allow an installer to connect the drive to the power steering system, whether that means a differently positioned steering cylinder or an alternate style of power assist.

This universal actuator functions in the same way – it meters hydraulic fluid to the steering cylinder, mimicking the actions of the helm. It’s compatible with 12V systems and draws power through the ACU-200. A major benefit is that the Raymarine Universal Stern Drive kit is designed with the installer in mind: the package includes detailed instructions and an assortment of brackets that can be configured as needed. For example, if the steering ram is mounted in an unusual spot or access to it is limited, the kit provides extended hoses, T-fittings for various hose diameters, and brackets that can secure the drive at different angles.

The universality of the E12026 makes it suitable for boats where other drive units would require significant customization. This might include older Volvo Penta models from the 1980s/90s or other brands of sterndrive (OMC, Yamaha I/Os, etc.) for which Raymarine doesn’t offer a dedicated drive. The universal sterndrive bridge fills that gap, allowing even those vessels to be outfitted with a modern autopilot.

In operation, the user experience is the same as with the standard unit – the autopilot holds course confidently, and you can always take over simply by turning the wheel. Thanks to the universal drive’s clutch, you will instantly feel the wheel “come alive” and directly connected to the outdrive as soon as you disengage the autopilot. This ensures steering remains safe and predictable.

The ruggedness of the E12026 is top-notch: it’s intended as a professional-grade piece of equipment. It withstands engine and transom vibrations, as well as extreme temperatures in cramped engine bays. Its components – motor, housing, valves – are the same as or enhanced versions of those in the standard model, meaning you’re getting tried-and-true technology applied in a more adaptable form.

Application example: An owner of a 34-foot boat from 1995 with twin Volvo Penta drives and no factory autopilot option can install the E12026. The installer uses the provided adapters to tie the drive into the boat’s dual steering pump. After installation and calibration, the boat now has autopilot – it can maintain a straight line on long inter-port runs, and when trolling around fishing spots, the captain can rely on the autopilot to keep a steady course while they watch the fishfinder and radar.

In summary, the Raymarine E12026 Universal Sterndrive provides an all-in-one solution for adding autopilot steering to stern drives, especially when standard drives don’t fit perfectly. This device opens up the possibility for many more boats – even those with non-standard or older systems – to enjoy the convenience and safety of autopilot without costly helm system overhauls.
